Equipping the crane for operation in unprotected environments

Only with overhead travelling cranes

Long-term usage of the crane only in weatherproof areas. Temporary use in unprotected environments (outdoors in rain, snow or cold weather) is permitted.

Should the crane be operated on a long-term or continual basis in environments without protection from the weather (outdoors, in rain, snow or cold), modifications must be made to the crane.

In windy environments, even short-term use is prohibited. If the crane is to be used in windy conditions, modifications must be made to the crane.

For the ambient conditions, see Technical data.

 

 

Rain and snow can penetrate the electrical components of the crane and cause malfunctions (e.g. a short-circuit).

 

Rain hood on the crane travel motor	Rain hood on the panel

   Attach a rain hood over the crane travel motor.

   Attach a rain hood over the entire wire rope hoist.

   Attach rain hoods over all panels.

 

 

Strong wind can cause the crane to move in an uncontrolled manner (even when switched off).

 

Example of a wind anchor at the end of the crane track

─     For cranes which are operated completely outdoors: The crane must be able to be secured in a resting position (at the end of the crane track) when work is completed. A wind anchor is located at this resting position for securing the crane.

─     For cranes which are operated partly outdoors: If the crane can be moved inside the building when work is finished, a wind anchor is not necessary.

 

 

This section only applies to cranes which can only be safely operated up to a defined wind speed.

 

Wind sensor for wind measuring system

The crane must be equipped with a wind measuring system. The wind measuring system warns if a certain wind speed has been exceeded. The crane must then be run to its resting position (at the end of the crane track) within a specified time.

A wind anchor is located at this resting position for securing the crane. Alternatively, the wind anchor can be of a design that secures the crane at any desired position.

The corresponding wind speed up to which the crane can be operated and the time in which the crane must be able to move to its resting position are both specified in the test log book.

Only with crane with radio remote control: In order to run the crane to its resting position within the specified time, the transmitter must be located where it is easily accessible.
