Installation Instructions
Installation of Hoist and Stoppers
Consult your dealer or the our company about the
rail and hoist installation. Be sure to have a
specialist firm carry out the installation.
(For installation of a 3t or heavier machine, it is
necessary to acquire permission for production.)
If traversing distance is too long, and connection of
another Box-rail is needed, carefully weld the two
Box-rail so that they are properly aligned with each
other. After welding, smoothly finish the welded
joint section, and the wheel and guide roller running
section. If joint plates are needed, attach them to
both the upper and lower surfaces of the Box-rail joint
section. Install a stopper on both ends of I-beam to
prevent overrun of wheels. Do not frequently
contact the hoist to the stoppers to stop the hoist. Be
sure to attach cushioning material, such as rubber to
each stopper.
Be sure to use stoppers larger than half of the diameter
of the wheels. Use identical size stoppers to the
double-rail type also.
Danger
●
Make absolutely sure that only a specialized subcontractor or persons with the expert knowledge is allowed to install
the crane.
⋅
Or else, electric shock, falling hook block and other accident may occur, causing an injury.
●
Install the crane only in an environment of the specified conditions. Avoid rain or water that the crane is not
designed for.
Warning
!
●
Be sure to provide both ends of the rails of the cross and longitudinal travel tracks with stoppers.
⋅
Or else, an accident such as the hoist falling off may occur, causing an injury.
●
Check that the structure where the crane is installed has the required strength.
⋅
Or else, an accident such as the hoist falling off may occur, causing an injury.
Ground Wiring and Installing Earth Leakage Circuit Breaker
To avoid electrical shock due to fault current, be sure to install a ground wiring and install
an earth leakage circuit breaker in the electrical line.
Install class C or Class D electrical grounding according to Electrical Equipment Technical
Standard and Internal Wiring Standard.
(For a Class 400 V power line, use Class C electrical grounding and grounding resistance of 10
Ω
or less.)
○
For motored traversing hoists
Ground the I-beam or rail as shown above. Do not coat the wheel running surfaces.
