The lifting accessories should be in good condition 71215 safe for whatever operations are being covered.

Operation of limit switches, check valves and similar devices could prevent some motions of the crane 71211-5 the carrier still suspended. Nuts and bolts manufactured from high tensile steel or other special steels carry markings 7211-5 that they can be distinguished from other nuts and bolts.

Those responsible for the selection of personnel should ensure that the personnel involved in the operation are 712-15 organized in order to ensure good team-work in the working situation. Cruciform bases cover a larger area than cast-in bases and therefore might not be suitable for congested sites.

Diagrams and drawings in the crane instruction manual relating to erection and dismantling should use the same system of marking and show the correct location and orientation of components. Personnel should only stand on or work from the floor of the carrier.

Inadequate employee training is a contributory cause of crane accidents, which result not only in significant damage to plant, but also in severe injury to those doing the work or those nearby.

71215- part of the planning process it is important that the b and construction of the base is taken into account, together with the connection to ground or adjacent structure.

BSBS In such cases means should be provided for rescue of persons in the event that a fall results in them being suspended at the end of a lanyard.

Fire extinguishers Fire extinguishers should not be 7121-55 or used in the cabs of tower cranes as the confined nature of such cabs exposes the user to the risk of suffocation.

When choosing high visibility clothing, backgrounds, type of illumination and other relevant factors should be taken into account. During the installation operation the wind speed should be periodically monitored using a calibrated handheld anemometer.

For longer periods, or when the crane is not in use, the transmitter should be deposited in safe storage. The following points are important.
