All about rolling jacks

Model "Bison"

Considering this 3 t rolling jack, its description should begin with design features. The device is made with a wide heel, and therefore is in great demand. If you believe the opinion of buyers, the model is equipped with a solid frame. The length of the beam in this case is equal to 28.5 cm. The direct bearing stop in the presented configuration is used with a rubberized pad. The handle of this jack is of a fixed type.

The holder is installed on the model, and this is an important advantage. Also, this model is in demand due to its low fit. The minimum lift height is 125 mm. The jack protector is installed in the upper part of the housing. The model has two racks in total. The piston system is located at the handle. Tray for storing tools not included in the presented configuration. The frame in this case is U-shaped. Front holders are mounted on brackets as standard. This trolley jack 3 t "Zubr" is worth no more than 3400 rubles.

Powerzone 380044

Excellent high quality mid-range variant tested by drivers. Powerzone is an aluminum construction weighing 27 kg. Jack with a capacity of 3 tons with a lifting range from 100 mm at a minimum height to 480 mm at a maximum height. It has a split handle that allows the user to easily create the levers needed to lift the vehicle. There is a very convenient storage box when not in use.

The front rollers are fixed and bi-directional, while the rear wheels pivot, allowing this jack to move freely. Another nice feature it has is a rubber cushion that protects the car from damage. Compared to the Arcan, the build quality is slightly worse, but it's the best compromise for a budget price in the $ 100 range.

Views

The correct choice of one type or another, as well as a specific model of a lifting device, is sometimes quite difficult to make.

An equally important point is the variety of rolling jacks, which differ from each other in basic operational properties.

By carrying capacity

In this case, we mean the main characteristic of any car jack.

It is important to take into account that the use of the device outside the regulations poses a potential danger to itself, the vehicle, as well as directly to human health and life. When buying a lift, it is highly recommended to calculate potential loads and choose a model with a capacity margin

Taking into account this parameter, the mechanisms currently presented on the market can be divided into the following categories.

Lifts for passenger cars, used most often in garages and having a carrying capacity ranging from 1.5 to 2 tons. Since the mass of such vehicles rarely exceeds 2 tons, purchasing a more powerful jack is unlikely to be advisable.
Professional models for car services, the described indicator of which starts from the mark of 3 tons. This is due to the variety of vehicles served with different weights.
Lifting mechanisms for trucks

In this case, it is important to take into account not only the weight of the car itself, but also its carrying capacity, since it is often necessary to service the same trucks in the equipped form. For example, if the mass of a car is 8 tons, and its maximum carrying capacity is 10 tons, then you need a jack that can withstand 18 tons.

Pick-up height

Another important characteristic of any car lift, which directly determines the possibility and features of using a particular rolling-type model. This refers to the minimum ground clearance at which the jack can be installed.

Based on the foregoing, when buying a rolling device, it is strongly recommended to take into account the pickup height and compare it with the ground clearance of the car itself. As practice shows, in situations with cars with a ground clearance of less than 14 cm, the best option will be precisely the described jacks, the pickup of which is from 7 to 10 cm... Otherwise, the use of a lifting device will become extremely difficult, and in most cases, simply impossible.

By other parameters

In addition to the two listed parameters, the limiting height of the lift plays an important role in the classification. It should provide the ability to carry out certain repairs or maintenance of individual components and assemblies of the machine. As in the situation with the carrying capacity, it is better to have at least a minimum margin, since it is necessary to take into account, for example, the free travel of the suspension.

We can talk, in addition to a banal wheel change, including the repair or maintenance of the steering rack. At the same time, regardless of the performance of rolling structures with a sufficient working height, you should always remember to use reliable supports for belay. By the way, if there is an appropriate supporting surface, such jacks may well be used if the car is stuck off-road.

Another important point is the type of mechanism, which is a key structural component of any jack, including the type described. The overwhelming majority of models available on the modern market are equipped with gear or cardan power units. Also, devices are classified according to their lifting speed. So, some representatives of the model lines of leading manufacturers are equipped with mechanisms that allow increasing the speed at low loads.

Trolley

Lifts are in high demand due to their versatility, ergonomics, and quick lifting. The review contains top models that experts recommend for purchase.

KRAFT KT 820005 (3 t) - German development

Trolley hydraulic jack, designed for vehicles weighing up to 2.5 tons. The model was developed in Germany and manufactured in China, which made it possible to significantly reduce the cost for the end user. Compared to competitors, KRAFT KT 820005 has two important qualities.

The jack is capable of lifting a car to a height of 385 mm with a pickup at the level of 135 mm. It can be used to change a wheel on an SUV. The assembly is carried out at a level, which affects the reliability of the lift, the term of use.

Advantages:

  • hardy;
  • build quality.

Disadvantages:

low lifting height.

The main aspects or how to choose a quality trolley jack for a car

  • Maximum lifting height - before choosing a jack for a car, you should know how high it is able to lift the car. If the lifting height is not enough, then the performance of some operations will be complicated.This parameter is especially relevant for owners of crossovers and SUVs, because such cars have not only a larger wheel diameter, but also the suspension travel is increased.
  • Minimum lift height - the number indicates the minimum height of the device in the folded position. This indicates which vehicle the tool can be installed under. Usually manufacturers make devices with a minimum height of about 140 mm, which is quite enough for working with a passenger car. For sports models, movements with a minimum height of 75 mm are produced. In any case, when choosing, you need to build on the size of the clearance of your car.
  • Carrying capacity is an important factor that must be greater than the weight of the vehicle itself. Therefore, before choosing a rolling jack, find out the weight of your vehicle. Most of the devices have a carrying capacity of 2-3 tons, which is quite enough for a standard passenger car. Owners of SUVs or minibuses should look for a more powerful mechanism.
  • Mechanism type - the unit is responsible for the transfer of force from the handle to the valves. There are two types of mechanisms: cardan and gear. Most reviews mark the gimbal design as the most reliable and easy to repair.
  • Lifting speed - this parameter is important for those who have a car with high ground clearance in their garage. Some device models have a special knob or pedal that allows you to force the process.

The listed parameters are basic, it is on them that the comfort of operation and trouble-free operation of the device depend. But it doesn't hurt to take into account a number of additional factors.

Additional accents

A steel tool will last a long time, moreover, it is more reliable. Many will be surprised, but some specimens are made of aluminum alloys. The length of the drive handle plays an important role; for the operation of lifts with a lifting capacity of more than two tons, long handles are more suitable

It does not hurt to pay attention to the presence of the following details:

  • Position lock - ensures the safety of the work being carried out.
  • Rubber stops - allow you not to think about the pencil for removing scratches and preserve the paintwork of the car.
  • Protective caps on the plungers - prevent moisture and dirt from entering the system, thereby eliminating the formation of corrosion.
  • Ergonomic handle - contributes to comfortable work with the tool.

Anyone who is interested in how to choose the right hydraulic rolling jack should pay attention to the material of the oil seals. Usually they are made of rubber, but this is far from the best option.

The best operational results are demonstrated by polyurethane seals.

Another nuance is the coating of the stock. Chrome plated models are virtually corrosion resistant. The reliability of the structure depends on the quality of welding. The seams should be smooth, without any flaws.

Features of the operation of the rolling jack

Having decided on which rolling jack is needed, it is worth considering the peculiarities of its operation. A feature of operation is the need for periodic pumping of the entire hydraulic system. This will help avoid or reduce the risk of the jack spontaneously folding under the load. Typically, the instructions for use clearly describe the sequence of steps to be taken on how to pump the hydraulic jack.

In addition to the possibility of leaks in winter, the working fluid can simply freeze, which must be taken into account among all factors. Well, it is also worth recalling that next to the jack in the trunk there should be a simple support tripod - your guarantee of the safety of repairs.
Since rolling jacks have steel wheels, it is possible to move the jack in some positions and on slides, especially when it is loaded.Therefore, you should take measures to help eliminate this danger: stops, backing stoppers, etc.

Lifting mechanism service life

After analyzing customer reviews, you can see that many are worried about the same question about how to extend the life of their purchased forklift. And this is understandable, because despite the observance of all safety rules, the stroke of the stock over time becomes not as smooth as it was at first, and now you can see that the machine does not rise smoothly, but as if with some incomprehensible jerks.

But the longer the hoisting device serves you, the more problems arise over time. So, for example, the lifting speed becomes much slower, therefore more effort is required for lifting. And therefore, you should not delay the repair of your equipment for a long time, and having seen only the first signs of such work, it is worth starting to maintain and control it.

Maintenance of the lifting mechanism does not require particularly great effort and time-consuming. First of all, do not forget to add oil. It is known that during operation it can flow out of the oil seals, and it can just get dirty.

From time to time it is worth checking the presence of excess air bubbles in the hydraulic cylinder. It is necessary to pump it without lifting the load so that excess air leaves the device.

Pay attention to the details that rub. For their normal operation, special care is required, which consists in lubrication.

But make sure there are no oil leaks. Inspect and fasteners so that later you do not have any trouble with them. Remember to store the lifting mechanism in a dry place. If you follow all these rules, then the operating life of your lifting device will be long.

Features of the design of the rolling jack

The rolling jack is not designed to lift a load to a great height, but it can easily withstand up to two and three tons, depending on the model. The model range is very diverse, you can find options in which the principle of operation is based on pneumatics, and there are also spring ones. In a special place there are automobile rolling jacks, which require hydraulic or pneumatic force.

What one of the rolling jacks looks like

The trolley jack design has several main parts:

  • Housing (aluminum or steel).
  • The main cylinder of the hydraulic system.
  • A hydraulic cylinder rod that controls the lifting platform using a system of power levers and reciprocating movements.
  • Swivel lifting platform.
  • Plunger.
  • Handles and levers.
  • Drain valve control screw (required to relieve pressure and lower the machine).
  • Spring (needed so that the jack piston takes its original position when the pressure decreases in the system).
  • Transport handle (not available on all models).
  • Metal wheels.
  • Cover to prevent dust and dirt from getting into the safety rod.
  • Hydraulic repair kit.

An important aspect when choosing a mechanism is its functional side. Since the components may differ from model to model, it is necessary to focus on how the device is planned to be used.

In this regard, it should be understood what characteristics a rolling jack has:

  • Carrying capacity. There are rolling jacks for both 20 tons and 2 tons, 3 tons, 5 tons, etc. A jack for two tons is perfect for owners of cars, and owners of heavier equipment will have to choose a device designed for 3 tons, for example, this may concern avid "Jeepers". The main thing for this characteristic is that the weight of the machines does not exceed the limit value of the jack.
  • Gear or cardan mechanism for transmitting force from the handle to the shut-off valve.Most experts recommend choosing a cardan transmission, noting its reliability and durability. In addition, if a breakdown occurs, then its repair will be easier and cheaper.
  • Ascent speed. It may differ from model to model. For example, the presence of an additional pedal already implies a higher speed.
  • Lifting height. Owners of crossovers or SUVs need to choose a rolling jack that can lift a car to a height of 45 cm, otherwise the wheel cannot be removed. The usual range of a rolling jack is from 12.5 cm to 14 cm, but there are also low-profile mechanisms designed for a height of 7.5-9 cm.
  • Convenience and comfort in use. They are equally important in the operation of the device. The presence of a rubber support for a rolling jack on the lifting platform will significantly increase this characteristic.

Installation of other types of jacks

Any others types of mechanical and hydraulic jacks are placed under the ledge, at the junction of the threshold with the bottom, where there is a special rib for this. With a pneumatic jack, due to the large area of ​​the upper and lower sides of the pillow, there will be no problems. When using, first of all, standard Duster jacks, hydraulic, rack and pinion and any inflatable jacks, after lifting the car, it is immediately necessary to substitute a gantry support - a stand, and only then start work.

The rolling jack on Renault Duster is installed in the same way, it should only be taken into account that it needs a large support area, but on the ground, because of this and the presence of rolling rollers, it will be difficult to use it. It is also necessary to remember that the bottle lift (depending on the model), due to the high pickup, may not fit under the car's jack platform, with the wheel completely flat.

Which company is better to give preference

Automotive tools

Jacks are in great demand among car owners, therefore, a large selection of products of both Russian and foreign production is presented on the market. The rating by manufacturing firms was selected taking into account the presence of an extensive network of sales points.

The rating of car jacks consists of the following companies:

  • Zubr OVK is a Russian company that manufactures sophisticated technical equipment. Jacks from this manufacturer are easy to use but reliable. Because of this, they are very popular with drivers.
  • Another popular Russian manufacturer is Sorokin. The only drawback is the high cost of the tools. Most often they are used by large service stations. In addition, rare electro-hydraulic models can be found in their assortment.
  • More than 50 modifications of jacks can be offered by the Russian company Airline. The main difference from other manufacturers is the availability of our own development for the manufacture of bottle hydraulic jacks up to 50 tons.
  • Matrix is ​​a company that offers a large selection of rack, roll and bottle models. Here both large service stations and motorists will find the necessary tool for themselves.
  • Autoprofi is a Russian company that sells automotive chemicals, car tools. The manufacturer's advantage lies in its reasonable prices.

Choosing which jack is better for a crossover or a jeep, you can focus on the rating of these companies that have proven themselves in the market for high quality tools.
