3 Information signage content
3.1 Manufacturer information
About the tower crane manufacturer information should be in accordance with GB/T 23725.1-2009 2.1 instructions.
3.2 nominal weight information
Each tower shall be equipped with clearly marked with text and graphics permanent nominal weight chart, and is fixed to the tower crane driver can speak
As seen at the location and time of the remote station. The contents of the chart should include, but are not limited to.
a) In determining the working radius, boom length, lifting rope under magnification and, if necessary, should also be considered from each available speed range of the hoisting ropes
Cranes and recommended counterweight configuration under full rated load;
b) preventive measures and procedures limiter device related or warning;
c) maximum allowable working wind speed;
d) recommended that the spreader device and its subsidiaries as part of the load. If the next portion of the load sheave block is considered, you should
Rated weight chart instructions.
Additionally, it should make the tower crane driver from the operating position is easy to nominal weight and the corresponding magnitude of identification being displayed. If the arm at work
Length and angle of the frame is changed, it should also display angle.
If signs showing nominal weight or metal sign mounted on the boom, they shall be so arranged tower crane driver and clearly legible
see. Due to work on a variety of configurations for a tower crane, the data and the display should be consistent with the actual configuration.
4 tower crane driver information operations
4.1 Control and indicator
All controls shall be marked with the text or graphic symbols to indicate their function and, if necessary, should indicate the direction of action. This information should be easy to identify
