Wheelift Systems’ self-propelled trailers (SPT) come in capacities to 100 tons and are ideal for in-plant operations with congested, confined areas and narrow intersecting aisles. The trailers feature computerized independent steering, on-center rotating front axles, remote control operation, low-profile design and on-board power generation. Typical applications include moving very large and awkward assemblies through manufacturing and assembly processes.
Each self-propelled trailer has two on-center rotation, electronically steered and driven independent axle assemblies on the front end. At the rear are two fixed direction rocker beam mounted axle assemblies, each with lateral articulation capability to assure fully equalized load sharing. This configuration allows for new levels of maneuverability.
