first slowly. Then, pull the load chain to loaded side slowly. Free spooling will
be available automatically.
● Notice on adjusting
the load chain length:
a) Free spooling manipulation will be impossible when the unit is used in such
a manner as the load chain is given impact.
b) Free spooling manipulation will be also impossible when the brake is
actuated.
c) When the unit is in such states as above paras.a) and b), set the selector
lever to the “DOWN” position and manipulate the operation handle and the
free spooling after the brake is released.
2. Making use of the feed handle
To tighten the load chain which is a little loose, set the selector lever to the
“UP” position to turn the feed handle clockwise. By this manipulation, the load
chain will be quickly tensed.
CAUTION ON CO-HOISTING BY MORE THAN
2 SETS OF CHAIN LEVER HOISTS
● Co-hoisting by more than 2 sets of chain lever hoists may be very risky
depending on installing and using them.
※
Pay attention to balancing of a load as stated below;
● When a combination of 2 lever hoists with different capacities is used, make
sure that the hoist with a smaller capacity is not severely loaded.
● When a load is lifted parallel by a number of chain lever hoists, make
sure that the load is not unevenly carried by them.
● When a number of chain lever hoists are used in a lengthwise row, select
hoists with an equal rated load.
※
A combination of hoists with different capacities will be very risky when a hoist
with bigger capacity is operated.
● Use wire ropes, clips, shackles, fitting pieces etc. which are sufficiently strong
for slinging the top and bottom hooks of the chain lever hoist.
● When it is used as an additional hoist for a big crane, select a chain lever hoist
with a bigger capacity than the actual load. Furthermore, do not operate the
crane in a manner of so-called earth-lifting. Otherwise, the chain lever hoist
will be damaged.
● When a number of chain lever hoists are used or one is used in combination
with other machines, do not overload the chain lever hoist. Use the chain lever
hoist in a well balanced condition, making sure the safety.
