①: Relay box
②: Manual handle
Precautions
●
The brake inside the motor locks the device when the hoisting motor is stopped.
If you do not release the brake according to the instructions on the precautions plate on the
③ hoisting motor, the manual handle does not rotate.
③: Hoisting motor
④: Hoisting pipe
⑤: Gland clamp
⑥: Brake knob
Procedure for Manual Hoisting
1. For your safety, do this procedure after cutting the power to the hoisting motor.
2. To release the brake, tighten the two bolts on ⑥ . Then, after releasing the brake, begin hoisting.
3. After use, completely cover the slot using the insertion cap for the manual hole. Then turn
on the power.
4. After using the manual handle, place it in the manual handle bag and keep it in a safe place.
• Stores electrical parts and the control board
• Use only when doing hoisting operations without the power to the
hoisting device turned on.
To use, open the insertion cap for the manual handle.
• Uses a 100 W, 24 VDC brake with a gear motor. The optimal
adjusting current value of the thermal relay for the motor is
approximately 6.6 A. Be aware that the thermal relay does not
operate as a breaker when the current is unstable.
Additionally, the thermal relay is set to automatic recovery.
• This is the central pipe for the hoisting part. The cable for the
transducer is stored inside.
• V packing for waterproofing from the seawater is inserted under
this gland. Water leaks can occur due to friction, etc., if you use it
for long periods of time. If this happens, temporarily loosen the
hex socket head cap bolt. Adjust the tightened height by removing
spacers for adjusting the height, and then tighten the gland
tightening bolt. Be aware that overtightening causes hoisting
operations to drag. Remove the same number and type of spacers
so that the height stays even.
• This is the screw for mechanically releasing the brake without
energizing the hoisting motor. You must be sure to release the
brake part if you are using the manual handle.
