1-next link of the mast；
2-the middle link of the mast；
3-the transmission chain;
4-adjusting bolt；
5-adjusting lock nut；
6-chainwheel；
7-chainwheel shaft；
8-the last link of the mast
3 When regulating the length of the chain,
please select the mast that needs
increasing its height. As shown in the
sketch, regulating the nut 5 tightly makes
the last link of the mast 8 move upwards.
The dual nuts 5 should be connected with
each other tightly after regulating the
length of the chain.
4 The same link of the mast is pulled by two
chains and endures the raised weight
loads at the same time. If one of the chains
loses efficacy, the other will play an
important safety role; therefore, try to
make both chains as loose or tight as
consistent each other when regulating the
length of the chain. The methods of judge
at site are as follows: Press the two chains
by hands to compare their tautness under
lifting status.
Make sure the chock is in
place during maintenance
When the work platform of a
AMWP needs to be raised for routine servicing
purposes, a captive chock shall be used to
enable the extending structure to be held in
the required position to prevent work platform.
