Control box that houses the electromagnetic switch, control board, and
clinometer (For details, refer to 7.2 Hoist control box.)
(2) Rocker switches
Power supply ON/OFF switch of the hoisting system with a built-in circuit
protector (10A) (For details, refer to 7.2 Hoist control box.)
(3) Cable gland
With this, by holding the cables of (8) transducer at the outlet of the hoisting
pipe, the cables can be fixed and packed.
(4) Gear box
This houses the drive gears. When the top cover is opened, hoisting operation
is stopped.
(5) Cable fixing brackets
For fixing the cables from the transducer
(6) Limit switch
Switch for stopping the hoisting operation when the switch is turned ON,
restricting the hoisting operation at the upper and lower limits
(7) Guide ring
Through this, the loads from driving resistance and vibration when the (8)
transducer is projected to the hoisting pipe are reduced.
(8) Transducer
The transducer has a built-in ultrasonic oscillator. The “FWD” mark of the
transducer needs to be aligned with the “FWD” mark of the clinometer when
