Design differences: hyd car lifts vs hyd lift tables

Design differences: hyd car lifts vs hyd lift tables

Design differences: hyd car lifts vs hyd lift tables

(OP)
A typical auto lift has a ratcheting stop to bear the weight of a vehicle while it's being worked on.  A hydraulic lift table with the same capacity will have things like OSHA electric toe guards to automatically stop lowering and a brass velocity fuse to maintain pressure in case of a failure.  But no physical stop.  Is this simply because the user will spend less time underneath the load of a lift table than they would under a vehicle lift?

I'm a non-engineer who is curious about the design differences between these two tools.  I'm considering using a lift table for ATV maintenance, but don't know if I need to add a stop mechanism.

RE: Design differences: hyd car lifts vs hyd lift tables

I would still want a manual pin or something to protect toes and feet.
If you have not yet purchased, check out the Handy Mfg air lift table. built rugged as a tank, and has the mechanical ratchet on the lift position.

I have used two of them. good prices for the build quality, very stable, and made in USA.

RE: Design differences: hyd car lifts vs hyd lift tables

for some reason I can't edit my above post.
Forgot to add: I bought the little trolley to move it around, works great. Also bought the front wheel vise, which I have mounted on another motorcycle lift right now, but it works awesome.   Side extensions I made from planks. The purchased metal ones would be better for ATV because the surface of the planks is up above the main table surface. I very rarely use the planks because for motorcycle narrower is better.

Thanks.  I'm still puzzled as to why a 5K lift table doesn't have any kind of stop, outside of the one for maintenance.  It could be that there are some fundamental design differences.  It could be that people rarely get underneath lift tables.

I wonder if it's harder on the table's hydraulic systems to carry loads for long stretches.  Even with the weight of the table top, I'm sure many tables are not parked in the full-down position.

Is the one in your picture really a hydraulic lift? It may be an electric screw actuator, and designed for self locking when not energized.

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
White Paper - The Other Side of Design for Assembly
Assembly level constraints need to be satisfied before the design can move downstream. This white paper will go through the various assembly level issues, which need to be tackled by various organizations on a regular basis. Know more about DFMPro, a design for assembly software. Download Now
