All lifting devices, from a simple lever to a powerful crane, can make a significant contribution to handling heavy objects and loads. A lift designed for handling vehicles in a service workshop is no exception.
Successful auto repair shop owners know that without this equipment, it's impossible to quickly and efficiently diagnose or repair vehicles, so they invest in lifting equipment.
Design features and their functional elements
Due to the specific nature of tire fitting and other repair work, technicians must access the vehicle's underbody, where the vast majority of serviceable components are located. This explains the lift's design, which clearly distinguishes itself from similar equipment—it features two identical posts. Additionally, the device is equipped with:
- hydraulic or mechanical drive;
- electric motor;
- synchronizing cable;
- special grips with a softened rubber surface.
This simple and highly functional unit is controlled by a remote control. A two-post lift allows the auto repair shop to handle a wide range of tasks, thereby expanding its service offering.
Parameters of two-post structures as the main selection criterion
The main criterion for every towing device is its load capacity. Double-post designs, made of extra-strong stainless steel, have a load capacity of up to 5 tons, making them suitable for handling not only standard passenger cars but also heavy SUVs and even some minibuses. Further parameters are monitored in the following areas:
- dimensional characteristics (distance between racks and lifting height);
- speed of the lowering procedure and opposite actions;
- smooth running and noise accompaniment;
- operational safety and ease of use.
The manufacturer's warranty period is also important; for lifts it is at least 10 years.
When evaluating the components responsible for performing the primary functions, the hydraulic drive (in one or both struts) is unrivaled. It significantly outperforms its mechanical counterpart, which requires muscular effort to activate.
