There’s no one way to make a car lift or truck lift safer for the operator. Manufacturers of high-quality automotive lifting products are always looking for better, more secure lifting methods. As a result, many excellent automotive lift safety features are now offered to the consumer. Here are just a few examples of the great technological strides that reputable ALI / ETL certification partners have developed to keep you and your employees safe. Two-post Car Lift Automatic Arm Restraints
Because the various car lifting solution designs can be extremely different from each other, it makes sense that some safety features are specific to only one kind of car lift. Two-post car lifts employ swing arm assemblies that allow the operator to change the arm configuration to suit a wide range of vehicles. It is important that swing arm lifts employ restraint devices to prevent arms from shifting or dislodging after a car or truck is already mounted and raised. Higher-quality two-post car lifts will feature this safety critical element; typically a gear mechanism that automatically secures the arms into place whenever the lift begins to rise. The automatic gear arm restraints will only disengage again when the lift is in a safe, lowered state.

Four-Post Car Lift Anti-Sway Blocks
Four-post car lifts are principally suspension lifts that rely on their columns to contain the lifting structure via cables or chains, while simultaneously bearing the load equally between them. Since the four-post car lift is not a rigid structure, it was once common for lifts to sway slightly during raising or lowering operations. Anti-sway blocks are one method of minimizing sway and maintaining proper spacing. This is especially important to ensure that safety locks are always engaged and that each post or column is holding 1/4th of the overall weight.

Four-Post Car Lift Runway Ramps and Chocks
Be sure your auto lift is equipped with manual wheel chocks as the primary means to restrain vehicles from inadvertently rolling off either end of the runways. Automatic stops on the approach end and fixed stops up front should be provided on runway lifts as a secondary means to restraint.

Hydraulic Flow Restrictor
Hydraulic car lifts that are designed with safety in mind use specialized hydraulic flow restrictors or velocity fuses integrated into the hydraulic cylinders or hydraulic circuit to control sudden, rapid decent in the event of a hydraulic component failure. These essential safety devices can dramatically reduce or stop downward travel in a free-fall situation due to a hydraulic system failure other than the cylinders themselves.

Design That Address and Eliminates Pinch Points
Pinch points are not just mere annoyances like the name might suggest. Without supervision and careful operation, pinch points can result in damaged property and injury. Reputable manufacturers employ engineers to help identify potential pinch points for hoses and limbs, and then they remove them from the design of an auto lift.
