Abstract
A counterweight for a monorail hoist. The monorail hoist includes a single support beam and a suspended hoist assembly which is supported for movement along the support beam. The hoist assembly includes a support member which is transverse to the support beam. The counterweight is mounted on the support member. The counterweight is slidable along the support member to optimally balance the overall weight distribution of the hoist assembly. Once the counterweight is properly positioned to balance the hoist assembly, a locking device locks the counterweight to the support member to prevent any further movement of the counterweight along the support member. The locking device is also releasable to allow the counterweight to be moved to or removed from any location along the support member in order to accommodate any changes which may occur to the overall weight distribution of the hoist assembly. Preferably, a plurality of counterweights and cooperating locking devices are provided.
