Harrington hand push trolleys are moved along a rail or beam by the operator pulling on the hoist load chain or strain relief cable. They are a practical solution to moving loads where the number of cycles is infrequent, and the trolley mounting height is 15’ or less. Generally speaking, the horizontal force required to move a load is ¾% to 1-1/2 % of the lifted load. Harrington hand push trolleys are not limited to supporting hoists. They can be used to support fixtures having a need to move along a rail, special doors such as is found in airplane hangers or other items requiring overhead movement.
Outstanding features of the these push trolleys include:
Sure trolley tracking with specially designed contoured wheels that fit both tapered (S) beams and flat-flange (W) beams.
Maintenance-free, sealed precision ball bearings are lubed-for-life and offer smooth movement, with low friction and long life.
Strong engineered design offers compact design and light weight.
Trolleys are adjustable to fit a wire variety of beam flange widths.
Load equalizing suspension distributes the load to all wheels equally, preventing wheel overload conditions.
Hand push trolley is ideal for longer traversing distances.
Hand geared trolley is ideal for shorter traversing distances and precise load control.
