Note
If the chain fall is double or ever number, it is forbidden to hang the lower
hook in the reverse direction to avoid dangers(Fig. 4.4).

(e) Chain lubrication
The degree of chain lubrication plays an important
role on chain's service life .It needs to apply machine
oil or gear oil regularly to prolong the chain's service life.
The process of lubrication:
1. Keep chain vertically without load .
2. Erase dust and water stains on chain .
3. Lubricate each link of chain connection and load pulley.
After the lubrication,lift the chain up and down without
load in order to daub lubrication equably. (Fig.4.5)

4.4 Installation of electric chain hoist with electric trolley (See Fig. 4.6)
(a) Installation of trolley
(1) Insert the suspension shaft into the side plate G, and fix with them together with bolt
and nut.
(2) Input the suspension shaft with inner adjusting spacer inside, after putting the spacers,
the total width should be about half of the width of traversing beam.
(3) As the Fig. 4.6 shown, do installation step by step. Firstly, install suspender Tinto hoist
body, and insert the shaft into suspender T.
(4) Secondly, install the adjusting spacers on it. Put side plate S between trolley wheel and
electric case. And fix with adjusting spacer.
(5) The last step: using dowel pin and split pin to fix.

(b) Adjust trolley width (Fig. 4.7)
(1) A refers to the measure value when two side plates stretch outwards totally.
(2) B refers to the measure value when two side plates clamp inwards totally.
(3) To adjust the number of thickness of inner spacers, makes B equal to the size when
wheels on the two side plates close to beam.
( 4) To adjust the number and thickness of outer spacers, make A-:£;_ B
+
4mm.
(5) The disassembling procedures refers to trolley installation, and fixed with dowel pin.
