car lifting tools

Description of hydraulic jacks in the bodywork workshop:

Hydraulic jacks are essential tools in a car body shop. They are used to lift vehicles to facilitate access to certain parts, whether for repairs, inspections or maintenance operations. Here are some important technical features of hydraulic jacks used in an auto body shop:

Lifting capacity :

The lifting capacity is the amount of weight the jack can support. It is generally expressed in tonnes. It is essential to choose a jack with sufficient lifting capacity to support the weight of the vehicle you wish to lift.

Lifting range :

The lifting range is the maximum distance the jack can lift the vehicle. Make sure that the lifting range of the jack is adapted to your specific needs, taking into account the height of the vehicle and the space available in the workshop.

Minimum height :

The minimum height of the jack is the distance between the base of the jack and the top of the jack head, when the jack is fully lowered. This measurement is crucial in determining whether the jack can be inserted under the low vehicle.

Maximum height :

The maximum height represents the maximum distance the jack can reach when fully raised. It is important to ensure that the vehicle can be lifted to the desired height.

Construction and materials:

Hydraulic jacks are generally made from heavy-duty steel to ensure durability and strength. The quality of the construction and materials influences the robustness of the jack and its ability to safely support heavy loads.

Hydraulic system :

Hydraulic jacks operate using a hydraulic system. Make sure this system is well designed, with durable components and tight seals to prevent oil leaks.

Hydraulic pump:

The hydraulic pump is responsible for raising and lowering the jack. Opt for a jack with an efficient pump that allows for quick and effortless lifting.

Safety valve:

A safety valve is an important feature to prevent accidental overloads. It prevents the jack from lifting more than its rated capacity.

Manoeuvrability:

Some jacks are equipped with castors or handles to make them easier to move around the workshop. Manoeuvrability is particularly important if you plan to move the jack frequently.

Conformity certifications:

Check whether the hydraulic jack has been certified to comply with safety and quality standards. Compliance certifications ensure that the jack meets the standards set by regulatory bodies.

Stability and wide base:

A wide, stable base contributes to the safety of the jack by preventing it from tipping or overturning during use.

By carefully choosing a hydraulic jack on the basis of these technical characteristics, car bodywork professionals can be sure of having equipment that is reliable, safe and adapted to their specific needs.

Steps for using hydraulic jacks for car repairs :

Using a hydraulic jack in a body shop is a relatively straightforward operation, but it does require special attention to ensure safety and efficiency. Here's a step-by-step guide on how to use a hydraulic jack in a body shop:

Step 1: Choosing the right jack

Lifting capacity:

Select a hydraulic jack with the right lifting capacity for the weight of the vehicle you want to lift. The jack's lifting capacity must be greater than the weight of the side of the vehicle you are lifting.

Minimum and maximum height :

Make sure that the minimum height of the jack allows you to slide easily under the vehicle, and that the maximum height is sufficient to reach the area you want to work on.

Step 2: Preparing the vehicle

Parking on a flat surface:

Place the vehicle on a flat, stable surface. Make sure the handbrake is on and the vehicle is in park position.

Wearing protective equipment:

Before you start, wear the appropriate protective equipment, including safety gloves and goggles.

Step 3: Positioning the jack

Identifying lifting points:

Locate the lifting points recommended by the vehicle manufacturer. These points are generally located on the vehicle chassis and are designed to support the weight of the vehicle safely.

Positioning the jack:

Place the hydraulic jack next to the vehicle and align it with the chosen lifting point. Make sure the jack is correctly positioned and centred under the vehicle.

Step 4: Lifting the vehicle

Adjusting the height :

Before you start lifting, make sure the release valve is closed. Pump the jack handle to increase the height until the jack is in contact with the lifting point.

Progressive lifting:

Use the pump handle to raise the vehicle gradually. Monitor the process carefully and ensure that the vehicle lifts in a stable and balanced manner.

Stability check:

Once the vehicle is up, check stability by shaking the vehicle slightly. If the vehicle appears unstable, lower it immediately and reposition the jack.

Step 5: Working under the vehicle

Use of safety jacks :

Once the vehicle has been raised to the desired height, place safety stanchions under the chassis at appropriate points to provide additional support. This adds a layer of safety should the jack fail.

Planned work:

Carry out the necessary work under the vehicle, taking care to comply with safety instructions and not to exceed the recommended lifting capacity of the jack.

Step 6: Lowering the vehicle

Removing the jack stands :

Before lowering the vehicle, remove the safety stanchions.

Reducing the height of the jack :

Open the jack release valve and use the handle to gradually lower the vehicle. Lower the vehicle until it rests on the ground again.

Removing the jack :

Once the vehicle has been lowered, remove the jack from underneath the vehicle.

By carefully following these steps and observing the safety instructions, the use of a hydraulic jack in a body shop can be carried out safely and efficiently. It is crucial to always consult the recommendations of the jack and vehicle manufacturer to ensure safe operation.
