Fail-to-safe: The Benefits of the Basics.

When designing a piece of equipment safety is the single most important factor. Today it is easy to get lost in all the excitement of cutting-edge technology. We can often forget the comfort of the known.

The purpose of the SLT220 is to perform a dual point lift and secure the entire front or rear axle of a 400 ton haul truck in less than 3 minutes. The operator’s safety is increased by operating the SLT220 away from the truck’s shadow with a remote control.


We have successfully designed this heavy-duty piece of equipment with a secondary mechanical locking system. These locks use the concepts of simple mechanics and guarantee that the lifted truck will not collapse when engaged.
