Trolleys are available with a choice of hand push or gear operation. A hand pushed trolley is usually moved by pushing the suspended load. It is however possible to move the trolley by means of a winch or other pulling machine. A geared trolley is provided with geared driving wheels, which are rotated by pulling downwards on a hand chain driving an intermediate gear.
Push travel trolley is designed to suspend and transport a load along a beam by the use of the bottom flange and a set of rollers (or wheels) which enable horizontal traverse when pushed or pulled manually.
A simple fitting to an "I" beam makes push trolleys a favorite method of suspension and travel for many, the following easy steps are the basics of how a push trolley works:
Screw, clamp or bolt (depending on the type of trolley) the two side plates on to the bottom beam flange so that the wheels sit and roll along that flange. Clip your hoisting equipment in to place by fitting the hoist's top hook through the eye of the beam trolley bar.
Geared travel trolley makes light work of suspending a load with horizontal travel along an "I" beam, similar to the push trolley the geared version allows a hand chain to be pulled much like on a chain block, when the hand chain is pulled this rotates gears which rotate the wheels of the trolley to enable smooth and controlled traverse of the beam while a load is suspended.
Geared trolleys simply fit to an "I" beam just like the manual version, by bolting, screwing and tightening the wheels on to the bottom flange of the beam and fitting the hoist or lifting equipment to the trolley by hooking it through the designated eye. Available with custom hand chain lengths to suit your drop height, perfect for heavier loads that are hard to push.
