Car ​Hoist Safety Features

There’s no one way to make a car ​hoist or truck ​hoist 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 hoist 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 hoist 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 hoist. Two-post car hoists 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 hoists will feature this safety critical element; typically a gear mechanism that automatically secures the arms into place whenever the hoist begins to rise. The automatic gear arm restraints will only disengage again when the lift is in a safe, lowered state. Because this process is automatic, the operator does not need to worry about forgetting to secure the arms.

Four-post hoist anti-sway blocks

Four-post car hoists are principally suspension hoists 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 hoist is not a rigid structure, it was once common for hoists 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 hoist runway ramps and chocks

Be sure your auto hoist 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 hoist 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. When exploring lifting solutions, always make sure the car hoist design features these crucial components for consistently smooth operation and no surprises.

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 hoist.

Automatic safety locks

These powerful load-holding devices automatically engage and lock the hoist structure as the car hoist raises, preventing sudden free fall in the unlikely event of a suspension component failure. Typically, after the hoist is raised to the required working height, operators are instructed to lower the hoist until it is resting safely on the locks to minimize wear on suspension components. Once the locks are engaged, the car hoist has to be raised slightly in order to release the safety locks. The better car hoists on the market often have locks spaced no more than five inches apart to better protect operators or bystanders. Load-holding devices should always require an independent and positive action for release, and they should always engage and reset automatically each time the hoist is raised.

Slack cable or slack chain device safety device

As a redundant safety precaution, all professional-grade car hoists that employ either cable or chain suspension methods should incorporate a slack cable or chain device. These slack cables act as an automatic brake for the supported structure if a suspension component breaks or slackens.

Safe systems and procedures

When searching for a car hoist, always ensure the manufacturer has a written quality assurance system of policies and procedures that are implemented and managed by quality control personnel. Safety policies and procedures should embrace safety specific subjects like organization, functions, duties and authority; policy and procedure publication, change control and record keeping; engineering drawing and specification publication, change control and record keeping; manufacturing process conformance determination, change control and record keeping; raw material and purchased part conformance determination and record keeping; component and end item conformance testing and record keeping; calibration and record keeping and traceability to the National Institute of Standards and Technology (NIST), or other national standards, for all gauges, measuring devices, tools and instruments that affect the quality of the final product; and, control and disposition of nonconforming material.

Specialized lifting pads for different types of vehicles

Make sure you always have the right tool for every lifting job. Vans and trucks require different adapters than cars and motorcycles. The dealer or manufacturer should have a variety of options and accessories to help customize your automotive hoist to fit your specific auto lifting needs. If they don’t, take it as a sign that their car lifting products might lack the proper support.

Proper use and safety instructions

Always be sure that your car hoist is supplied with operation, inspection, service and maintenance instructions that include specifications of the lift, lift rated load capacity, significant hoist and bay dimensions, power requirements (compressed air and/or electrical), foundation and floor structural requirements. Car hoist installation instructions should be clear with graphics illustrating full step-by-step assembly, exploded drawings with part numbers and descriptions, component packing list, site requirements, mounting and anchoring instructions, recommended clearance around and above hoist, plan and elevation details of auto hoist layout, final pre-check procedure for assembled hoist, operational test & inspection and maintenance instructions.

Labeling

To raise safety awareness for all operators and bystanders, auto hoists should always include pertinent warning labels, as well as raising and lowering instructions. These labels shall be located at the point of hazard so that they will be plainly visible by the operator when he or she is in position to raise or lower the car hoist’s load.
