EnKon Systems, Herkules Equipment Corporation's brand name of lift systems solved a tractor manufacturer's ergonomic lifting problem by designing two heavy duty pneumatic scissor lifts that maintain a surface flatness of +/- ½" with minimal deflection, and providing a closed lift height of 8.5" enabling the tractor to be pushed onto the lift from an 8.5" height platform. EnKon's custom-made lifts utilized two sets of scissor arms. Each heavy duty lift was designed to support 6000 lbs. which would accommodate any future heavier tractor model additions. And the low-profile characteristics of the EnKon lift design enable the customer to accommodate the 8.5" high platform.
The customer was impressed with how stable the tractor-loaded lift was when in the raised position and appreciated the fact that the use of the air bearing system would turn a back-breaking burden into an easily accomplished task. The original lifting problem began when
the manufacturer introduced a new model whose weight exceeded the capacity of the lifts being used. The new tractor weighed 3000 lbs., and since the existing lifts were designed to accommodate only 2000 lbs. they began to tip under the excessive weight.
