摘要： An arrangement of pressurized air hoses and method for supplying pressurized air to pneumatically separated equipment such as hoists as the hoist is moved along a support rail. A series of pairs of lengths of air hoses are connected together at either end which are initially vertically oriented and packed together. As the hoist is manually moved along it causes the upper ends of the lengths to be swung apart from each other eventually becoming substantially horizontal. This movement causes the overall length of the series to be substantially lengthened allowing the hoist movement to occur while its need for pressurized air being maintained all along its range of movement.

摘要： A balancer hoist has an electric servomotor driving irreversible gearing in turn driving a hoist chain drive. A float mode and a manual mode are provided using two independent load sensors for sensing the load weight and force applied to a control grip. A traversing control is produced by a tractor carriage rolling on an overhead rail connected to a trolley also traveling on the rail and supported on upper hoist assembly. A load sensor interconnects the tractor carriage and upon hoist assembly to sense forces created by an operator pulling on the chain, which are used to control an electric motor on the tractor carriage driving a pinion gear engaged with a gear rack on the overhead rail to positively drive the carriage, trolley and upper hoist assembly along the rail. A stationary dual hoist system is also described in which two hoist assemblies are interconnected by a chain and sprockets to provide synchronized operation.

摘要： A plate assembly for mounting an electrical enclosure in a position vertically aligned atop an overhead rail used to support a traveling hoist which traverses back and forth along the rails on a trolley. The plate assembly includes a plate which is shaped like an inverted U by a central opening extending up from the bottom with mounting portions projecting normal to the plate which are configured to be attached to the enclosure when installed in the opening at the top and to respective rail pieces clamped against respective sides of the opening.
