Abstract

The mechanism is particularly for tower cranes, and helps the travel braking system. As the crane travels along the rails, lugs on its chassis come up against stops on the rails, and in so doing haul on ropes reeved over pulleys so as to raise the counterweight on the chassis. The energy involved is thus dissipated in lifting the weight, slowing the travel speed down virtually to nil when the brakes are supplied, and eliminating any shock loads. The weight itself can be that used to stabilise the chassis. The lugs can be in the form of levers pivoting on the crane chassis bogies, acting against stops in the form of bars across the track.
