Traveling motion of the Trolley (common for motorized/manual trolley)
Symptom Cause Remedy Main factor Countermeasure
Unable to travel due to
slipping of wheel
Inclination of Travel Rail Make sure that rail
gradient is within 1
degree.
Improper installation of
Travel Rail
Install the Travel Rail
correctly.
Unable to travel due
to slipping of wheel,
or unable to travel in
uniform motion
Oil attachment on
running surface of the rail
Wipe off the attached
foreign matter.
Use under the
environment likely to
attach foreign matter
Clean the Travel Rail
regularly.
Sounds abrasion sound
when running on a
curved rail
Friction resistance
between wheel and rail
Apply small amount of
grease on the rail surface
where noise generates.
Unable to travel on the
curved rail
Interference of the trolley
and the curved rail
Make sure that the rail
curvature is larger than
the minimum turning
radius. (See P43, 48)
Use of the curved rail
of curvature less than
minimum turning radius
Do not use the curved
rail of curvature less than
minimum turning radius
Unable to travel due to
wheel floating
Pulling a load in an
inclined direction (floating
wheel)
—
Operating method Use the electric chain
hoist correctly.
Wheel unable to rotate Defective gear
engagement
Remove the stain and
foreign matter on the
wheel and the gear.
Ambient conditions,
environment
Check regularly.
Meandering
Strange noise
Wrong adjustment of
collar
Check the number
of collars and their
assembled positions
Incomplete checking Assemble correctly.
Uneven abrasion of the
wheel
Check the abrasion of the
wheel
Traveling on curved rail
or unevenness of running
surface
Check regularly.
Deformation of wheel Check the distortion of
wheel and damage of
running surface
Excessively frequent
collision with stopper or
unevenness of running
surface
Replace the wheel
Use the electric chain
hoist correctly.
Deterioration of wheel
bearing
Check if rolling noise
sounds when the wheel
is rotating.
Expiry of service life Replace the wheel
bearing.
Deformation and
abrasion of the rail
Check the abrasion and
deformation of the rail.
Over load or expiry of
service life
Replace the rail.
Use the electric chain
hoist correctly.
