RECOMMENDED MINIMUM SAFETY DISTANCES TO BE OBSERVED DURING THE

ADJUSTMENT OF THE HOIST-LOWER LIMIT SWITCHES

FOR EMERGENCY HOISTING

All limit switch setting operations and re-setting safety-gaps must be carried out by specialised electricians

authorised by respective section heads.

PLEASE NOTE

When the emergency limit switch is open, it is no longer possible

to operate the crane using the normal controls.

Therefore it is necessary to continue in one of two ways:

· act on the line contactor manually and at the same time

lower the hook a few centimetres;

· by-pass the emergency limit switch contacts temporally and

lower the hook.

· find out why the "hoisting" contact did not work, repair the

fault and re

set the limit switch.
