The operating instructions shall describe the type of the hoist with clear reference to the present hoist.
The use for which the hoist mechanism is intended shall be clearly described. This shall also contain design limitations, e.g. the theoretical duration of service. The measures to be taken when the hoist mechanism has reached the end of its theoretical duration of service shall be described in accordance with ISO 12482-1.
Information regarding the utilisation of the hoisting and lowering limiter during normal operation and periodical inspection shall be given.
Optional features of the hoist, e.g. devices for lowering the load in the event of a power failure, shall be described. If a second limiter is required referring to 5.2.4.2 and this limiter is a friction torque limiter, the inspection of the function of the first limiter shall be described in the handbook.
The operating instructions shall always include the following instructions: 1) the necessary training for the operating personnel shall be described;
2) the user shall ensure that the operating personnel are given the necessary training; 3) the operator shall always work in compliance with the operating instructions;
4) the user shall lift the load from the ground with the minimum speed available at the hoist. The rope (chain, belt) shall be tightened and shall not be in the slack-condition when the load is being lifted from the ground;
5) it is forbidden to lift loads above the rated capacity of the hoist; 6) do not try to lift fixed or obstructed loads;
7) do not side-pull loads;
8) excessive inching (e.g. giving short pulses to the motor) shall be avoided; 9) ban on transporting persons.
All maintenance and repair work required to ensure the safe functioning of the hoist mechanism shall be described, e.g.:
i) lubrication of ropes, chains, gearboxes, bearings, hooks etc.;
ii) inspection of wearing parts such as ropes, chains, hooks, belts and brake linings. Specification of test and inspection intervals and discard criteria;
iii) operating principle of safety devices and requirements in the event that these devices are triggered, e.g. resetting the emergency stop device;
iv) in order to prevent hazards with heavy trolleys when changing wheels or guide rollers, the correct use of jacking or slinging points;
v) information shall be given how to verify the proper function of the limiters;
vi) measures to avoid possible damage of the hoist in case of incorrect phase sequence. The following information shall be provided, if necessary:
� limitations for operation, e.g. setting down the load when in the vicinity of the upper hook position.
For pneumatic and hydraulic hoists the following data shall be provided in the user information regarding the supply of pressurized fluid:
� pressure; � flow; � quality.
Regarding noise the following information a) to f) shall be given:
a) if the value of the A-weighted emission sound pressure level at the operator's position is lower than 70 dB, this fact shall be indicated;
b) if the value of the A-weighted emission sound pressure level at the operator's position exceeds 70 dB, this value shall be stated;
c) if the value of the A-weighted emission sound pressure level at the operator's position exceeds 85 dB, the A-weighted sound power level shall be stated;
d) for NGL building hoists the A-weighted sound power level shall always be stated;
e) the measurement procedure and detailed operating conditions during noise emission measurements shall be stated;
f) a recommendation for operators and servicemen to wear hearing protection when the hoist is used in a noisy environment or the A-weighted emission sound pressure level due to the hoist is high at the operator position. The manufacturer shall provide information on how to check and to set the rated capacity limiter. Setting and checking of the rated capacity limiter shall be done according to the instructions of the manufacturer by competent persons only. He shall request from these competent persons to document the test result in the logbook.
When the hoist is not fitted with a rated capacity indicator the manufacturer shall inform that this hoist shall be used only in those applications, for which the rated capacity of the hoist does not vary with the position of the load. For the installation and use of the hoist in supporting structures the manufacturer shall provide those information which enables the designer of the supporting structure to take into account the static and dynamic forces which may occur during operation of the rated capacity limiter of the hoist. Information to be provided (see 5.2.2).
