Wheelift’s Uniloadtm axle assemblies are designed to provide uniform loading across every tire, regardless of how many axles are involved or how badly the floor surfaces are. The “wheel modules” typically are furnished with 6” inches of vertical stroke, to provide sufficient compliance to undulating floors and for negotiating ramps when driving in and out of buildings. The unique part of the Wheelift technology, is the assurance that the transporter(s) are equaling sharing load across every floor contact point, regardless of surface irregularities.
Wheel modules typically share load by having their fluid lines being interconnect into three lift zones, to emulate the three-point suspension norm. In larger, more complex systems, or where multiple transporters are operating together, or where severe off-center loading can occur, every center column cylinder will have a pressure transducer being monitored by the SynchroSteer computer. Any change in floor elevation is immediately detected and electronically adjusted to maintain near exact floor pressure at that point(s).
Wheelift transporters are specifically designed for self-loading. As transporters drive into position under stand supported loads, when the operator selects lift, the transporters will lift to gain a solid “touch” with the underside of the load to be carried. Each cylinder will stroke until is sees a predetermined pressure that verifies solid contact between the base of the load and the floor. At that point SynchroSteer will note the stroke height of each cylinder and will compute the average. As the operator selects the “lift for travel” mode, the tranporter(s) will raise the load a few inches above the floor. In-part, by measuring the actual lift height across all cylinders in the system.
The operator or AGV navigation system has full control of that lift in event the transporter is negotiating the crown or valley of a ramp or other severe elevation change on all or just part of the wheel modules.
