Limiting devices
2 Limiting devices
A crane used in loading or unloading must have a motion-limiting device that:
prevents movement of the crane, and any load being handled, beyond the designed range of operations of the crane; and
operates automatically; and
for a crane other than a derrick crane - takes effect by interrupting the operating power so that the crane and its load are held stationary.
However:
a derrick crane that does not comply with paragraph (1)(c) must be fitted with a visual or audible alarm to warn the operator when the load is approaching the limit of the crane's range; and
for a crane installed before 17 November 1986 in which compliance for its traversing, travelling or slewing motions would be unreasonable or impracticable - it must not be operated beyond its safe limits.
