When slack chain or broken chain, please stop using the MEWP and
contact MEC immediately
Every link of the transmission chain is associated with three links of the
masts�����
Cover
Nut
ART_5958A
When regulating the length of the chain, please raise the platform to completely reveal the
window, and then remove the transparent cover. Regulating the nut tightly makes the last link
of the mast move upwards. The dual nuts should be connected with each other tightly after
regulating the length of the chain.
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
For routine servicing purposes, a captive chock shall be used to enable
the extending structure to be held in the required position to prevent
