the maximum static torque that would be transmitted to the brake by a suspended load of the maximum safe working load of the derrick served by the winch.
      (2) When the winch is under load, each brake must be able to arrest the motion of the drum that it serves, smoothly and without snatching.
      (3) A winch that is driven by an internal combustion engine must be constructed so that the load cannot fall by its own weight when the engine is disconnected.
      (4) A crane used in loading or unloading must have a braking or speed‑regulating system that:
(a) can arrest each type of motion of the crane:
 (i) smoothly and without snatching; and
 (ii) in the shortest possible time consistent with safe working; and
(b) for arresting the hoisting and luffing motions of the crane — can exert a restraining torque of at least 1.5 times the maximum static torque transmitted to the braking system by a suspended load of the maximum safe working load of the crane and operate automatically when the controls are in the stop position; and
(c) is activated automatically if the power drive or the control system fails, and allows for the load to be lowered during the failure; and
(d) does not allow a load to fall at a speed more than the design speed.

3 Electrically powered equipment
       For an electrically powered crane or winch used in loading or unloading:
(a) the operating modes of the controls must be separated by a neutral, stop or off position; and
(b) the braking system must come into operation automatically when there is a significant drop in the supply of electrical power; and
(c) there must be an emergency or isolating switch that:
 (i)  is conveniently close to the operator; and
 (ii) shuts down the power supply to the winch, or to hoisting, luffing, slewing, travelling or traversing motors; and
 (iii) does not affect lighting, indicators, electromagnetic lifting devices, cargo hook or twistlock controls, or other circuits not controlling the motion of the load or the crane.

4 Gear transmission
       A winch that has more than 1 transmission ratio must have a positive means of locking each gear shifting device.

5 Information on defined limits
       A crane used in loading or unloading must have, in a position conveniently visible to the driver:
(a) for a jib crane:
 (i) operating instructions, in English, for the range of outreach over which the luffing motion may be used and the safe working load for outreach distance within the range; and
 (ii) if the safe working load varies within the range of the crane — a device or instrument that continuously indicates the outreach; and
(b) for a
