Appointed Person

The role of the appointed person, as defined by BS7121 part 1, is to provide a safe system of work for all lifting operations which are properly planned and adequately supervised. This includes the preparation of a comprehensive risk assessment and an adequate method statement. As well as selecting the correct crane for the lift the Appointed Person must also select the appropriate load handling accessories ( chains, slings, webs ect), the method of attaching the load to the crane ( the slinging technique ) and calculate the down rating of the accessories where necessary to ensure a safe operation.

Crane Supervisor

The crane supervisor should direct and supervise the lifting operation, ensuring that these are carried out in accordance with the method statement. The crane supervisor should be competent and suitably trained and should have sufficient authority to stop the lifting operation if the supervisor considers it dangerous to proceed.

Crane Operator

The crane operator should be responsible for correct operation of the crane in accordance with the manufacturer’s instructions and within the safe system of work. The crane driver should only respond to a signal from the slinger to carry out initial lifting of the load, and then only to signals from one slinger/signaller, who should be easily identified, during the remainder of the lifting operation

The crane operator should be:

a) trained on the specific model of crane used:
b) Able to assimilate and apply information contained in reports and duty charts relating to the range of duties and safe use of the crane:
c) Familiar with the manufacturer’s instructions for the rigging operation and for maintenance of the crane:
d) Aware that the crane should be used on level ground or else set level on outriggers before any load is applied:
e) Fully conversant with the correct use of outriggers and were outriggers should be fitted, and aware of how to properly support the outrigger feet (this requires regular monitoring to ensure that no movement occurs throughout the operation):
f) Able to set and check the functioning of the rated capacity limiter and rated capacity indicator:
g) Aware of the effects of the wind other climatic effects on the crane load:
h) Able to resist pressures from other persons to carry out unsafe operations:
i) Able to take the action to avoid dangerous situations, including stopping operations:
j) Able to operate fire suppressant equipment, if fitted.


The signaller should be responsible for relaying the signal from the slinger to the crane driver. The signaller may be responsible for directing movement of the crane and load instead of the slinger, provided that only one person is responsible at any time.

During the lifting operation, hand signals and voice instructions to the crane driver should be given by only one person at a time. If, during the lifting operation, responsibility for directing the crane and load is transferred and to whom. The first signaller should clearly indicate to the second signaller that the transfer is taking place. The crane driver and second signaller should clearly indicate that they accept the transfer.

Note: it is common practice to train personnel to enable them to carry out duties of both slinger and signaller.


The slinger should be responsible for attaching and detaching the load to and from the crane load lifting attachment, and for using the correct lifting accessories and equipment in accordance with the operation plan.

The slinger should direct initial movement of the crane. If there is more than one slinger, only one slinger should direct initial movement.

If continuous signalling is required and the slinger is not visible to the crane driver, another slinger or signaller should relay the signals to the crane driver.

NOTE: Alternatively, other audio or visual methods may be used. If other audio or visual methods are used, the equipment or means of equipment use should be so that the crane driver can become immediately aware if the equipment fails, so that movement of the crane can be stopped.

The following indications of equipment failure should cause the crane driver to immediately stop movements of the crane:

a) Blank screen on television monitor:
b) Cessation of continuous instructions from signaller using radio, to e.g. “lower…lower…lower” etc:

NOTE: If radio is used as a means of signalling, the selected personnel involved should be kept clear of other communications. All personnel involved in signalling should be given a clear and unique call sign and all communications should be preceded by the call sign. The crane driver should not respond to the signals not preceded by the call sign.
