Schedule 7Requirements for lifting appliances(h) the distance through which a control is required to move for the full rangeof operations of that control must not exceed:(i) for hand levers, 600 mm; and(ii) for foot pedals, 250 mm,the distance being measured at the midpoint of the designed handgrip orfootrest for the control;(i) brake pedals must have a non-slip surface.3.2 Brakes3.2.1 A winch must not be used in loading or unloading unless:(a) a braking system is fitted for arresting the motion of each drum on which arope is wound, capable of exerting a restraining torque of not less than1.5 times the maximum static torque that would be transmitted to the brakeby a suspended load equal to the maximum safe working load of the derrickserved by the winch; and(b) when the winch is under load, all brakes are capable of arresting the motionof the drum that they serve, smoothly and without snatching; and(c) if the winch is driven by an internal combustion engine, the winch is soconstructed that the load cannot fall by its own weight when the engine isdisconnected.3.2.2 A crane must not be used in loading or unloading, unless:(a) it is fitted with a braking or speed-regulating system capable of arrestingeach type of motion of the crane:(i) smoothly and without snatching; and(ii) in the shortest possible time consistent with safe working; and(b) the braking system for arresting the hoisting and luffing motions of thecrane is capable of exerting a restraining torque not less than 1.5 times themaximum static torque transmitted to the braking system by a suspendedload equal to the maximum safe working load of the crane and operatesautomatically when the controls are placed in the stop position; and(c) brake systems are activated automatically on the failure of the power driveor the control system and provision has been made for the lowering of aload in the event of such a failure; and(d) the braking system is such that the controller does not allow any load to fallat a speed in excess of the design speed.3.3 Electrically powered equipmentElectrically powered cranes or winches must not be used in loading or unloadingunless:(a) the operating modes of the controls for the crane or winch are separated bya neutral, stop or off position; and(b) the braking system automatically comes into operation when there is asignificant drop in the supply of electrical power; and(c) there is provided conveniently close to the operator an emergency orisolating switch by means of which the power supply to the winch, or to66 Marine Order 32 (Cargo handling equipment) 2011MO32 modcomp-130604Z.docx
