Brakes that are fitted to hoists must apply their full braking action immediately on actuation.
The hoisting devices are usually powered electrically, hydraulically or pneumatically.
A crane trolley with hoist usually moves along the bridge girder, unless the gantry crane features a rail-mounted slewing crane.
The crane load hangs from a suspension element - using either lifting tackle or special load-handling attachments.
