Wire Rope Replacement
pg.9
GRADE
• The hoist is fitted with 7 x19 G190 IWRC wire rope.
When replacing rope ensure 7 x19 is used with a
minimum of grade 1900. If G190 IWRC is not available
it is quite acceptable to replace with a greater grade
such as G1960 IWRC or G2070 IWRC.
SWIVEL HOOK
• Put a new wire rope through the hole of the round
plate of the swivel hook
• Insert a sleeve pin through the thimble of the wire
rope
• Insert a pin through the sleeve pin and bend it with
pliers
DRUM
• Insert a new wire rope w/clamp through the limit
switch lever and insert
it into the hole of the drum
• Put a P.T. screw into the hole of the drum and tighten
it by a hexagon key
• Uneven winding of the rope may cause the load to
swing thus damaging the rope and reducing its life
span
OIL LUBRICATION
• The Hoists are prefabricated at the factory and do
not require initial lubrication.
• Re-lubrication interval depends upon service.
CARBON BRUSH REPLACEMENT
• It is essential to check the carbon brushes
periodically. If the length is less than .29”, it is
necessary to replace the carbon brushes immediately.
Two spare brushes are provided with each hoist at
time of purchase.
• When replacing, smoothly insert carbon brushes into
carbon holders, then put brush caps into the holes.
• Before tightening the carbon brush holders, make
sure they are positioned correctly.
• A set of carbon brushes consists of 2 pieces. Always
replace 2 pieces on opposite sides of the hoist body at
the same time.
