The push travel beam trolley is a type of beam attachment which enables you to not only attach a load to a beam but also to traverse it along its length. The beam may be part of the building structure but most commonly an RSJ beam trolley is used on the beams of a gantry crane system or Jib crane. Typically when a hoisting device is fitted to these trolleys, their chain and load hook or attached load are used to push and pull the trolley over the beam so a certain amount of physical effort is needed. A geared trolley is much easier to move and more widely used.
The majority of these push travel trolleys use a central screw rod which pulls together two side plates that incorporate the wheels around the flange of the beam. Within this screw rod, there is an eye which is used for the attachment of your hoisting equipment. This central screw pin should be checked on a regular basis to ensure it remains tightly fitted to the beam.
