We are able to offer you full lifting teams on site and can provide:
- Crawler crane operators.
- Mobile crane operators.
- Appointed persons (lifting operations).
- Crane supervisors (lifting operations).
Suitably trained personnel that are competent to carry out their duties are essential to the completion of safe lifting operations.
- Appointed Person (as described in BS7121 pt1 General) –The person responsible for the safe planning, control and execution of the lifting operation and producing the safe system of work (Method Statement)
- When planning lifting operations the following points should be considered, the list is not exhaustive. If you have any doubts when planning lifting operation then you will need a fully controlled and contracted lift to ensure the safety of your lifting operation.
- The load itself, its characteristics, lifting points etc.
- Load Stability whilst being lifted and maneuvered.
- Load route & motion speeds.
- Correct selection of crane e.g. dimensions, reach, lift height.
- Correct selection of lifting accessories and ancillaries.
- Crane position. Load position throughout the lift.
- Lifting area, to include proximity hazards, ground conditions, environmental factors, oversailing zones.
- Spacing for crane rigging and dismantling
- Choosing and identifying lifting personnel
- Environmental factors that will affect the crane and load.
- Lift / Crane Supervisor –The person responsible for supervising the lifting operation and safely operating the safe system of work (Method Statement) The supervisor will take on the duties of the Appointed Person in their absence. All operations should be supervised by a suitably trained and qualified supervisor.
- Slinger Signaller –The person responsible for attaching / detaching the load to and from the crane and directing crane movements during the lifting operation. The Slinger Signaller will;
- Inspect lifting accessories pre and post lift
- Use the correct accessories specified in the method statement
- Be able to communicate and direct the crane using audible and visual methods
- Crane Operator – Is responsible for operating the crane in accordance with training and manufacturers instructions. The crane operator should act on the instructions from one slinger signaller who must be clearly identified and working as instructed by the method statement. THE ONLY SIGNAL THEY CAN TAKE FROM ANYONE ELSE IS THE EMERGENCY STOP
- Crane Coordinator – When more than one crane operating on site, the crane coordinator will plan and work with the lifting personnel to direct crane movements to prevent collisions with other cranes and loads. The crane coordinator should be employed when other items of plant such as concrete pumps, mobile working platforms telehandlers and piling rigs are being used. This role is usually performed by an experienced Appointed Person

Operating In High Winds
All cranes have a maximum design wind speed for safe operation. When the wind speed exceeds this limit the crane must be taken out of service. Different types of crane, different models of the same type of crane and different configurations of the same model may operate with different maximum wind speeds. The operating wind speed for the crane will allow for
the load having a certain wind area; if this is exceeded then the working wind speed will need to be reduced (see the manufacturer’s manual for information on this).
Typical maximum operating wind speeds are:
Mobile Cranes 9.8 m/s (22 m.p.h.) Beaufort Scale 5
Proximity To Hazards
Hazards best avoided, where possible, include:
- Overhead electric lines
- Nearby structures
- Other cranes
- Public access areas
Where any part of the crane or its load cannot be kept clear of these hazards, the appropriate authority, e.g. a local electricity supplier or Railtrack, must be consulted.
Danger from vaults or underground services must not be overlooked, and suitable precautions must be taken where they cannot be avoided.
Where the crane or its load passes closer than 600mm to an obstacle, effective precautions must be taken to avoid crushing, by preventing personnel accessing the area.
Where a crane is to be used within 15 metres plus the length of its jib, from overhead power lines on steel towers, (or 9 metres plus the length of the jib, from overhead lines on wood, concrete or steel poles) the guidance given in HSE Guidance Note GS6 must be followed.
Where a crane will work close to railway property (i.e. if it fell over and any part of it, or any load being lifted by it, could fall on railway property), consult the railway property owner and CPES.
If the crane is within 6 km of an airfield, and its height exceeds 10 m or that of the surrounding structures or trees, then the Appointed Person should seek the permission of the airfield manager before starting operations.
Cranes have very high axel weights, and need good solid ground the same as a lorry would need. You will also need to make sure there are no sharp objects in the path of the crane when gaining access to the site.
