SPEED ADJUSTMENT
7.1 SPEED ADJUSTMENT
Every TCS hoist is checked at the factory to ensure the maximum hoisting speed is in accordance with the specification.
CORD CONTROL HOIST
The speed of the hoist is proportional to the amount of downward movement in the control cord, which via the cord lever controls the amount by
which the valve is opened.
For the pendant control, adjust the speed by varying the amount the lever is depressed. By depressing the lever slightly, you will be able to control
the hoists motions slowly with more precision. By depressing the lever further, the speed of the hoist will be increased until the lever is fully
depressed.
The TCS series is equipped with a speed adjustment mechanism. If you feel the lifting or lowering speed is too fast, the speed can be adjusted
slower as needed variably. Also please note that the speed can be adjusted separately for lifting and lowering.
HOW TO ADJUST THE SPEED
Referring to the diagram below, looking at the hoist from the valve side, the speed adjustment screw for lifting is on the RIGHT, and the lowering
adjustment screw is on the LEFT. Both adjustment screw are covered with a red plastic cover and can be removed using a pair of pliers. Behind
the plastic cover is a 'minus' groove and can be adjusted using a standard flat screw driver. In relation to the air hoist, as shown in the drawing
below, the vertical direction means the highest speed, and the horizontal position means the lowest speed. (Note: the hoist will stop if the speed is
adjusted too low) The adjustment can be made between these positions.
Adjust the speed only when the hoist is in stop mode. If the adjustment is made when the hoist is moving, it will be difficult to rotate the screw
since the air pressure increase the friction on the o-ring.
NOTE: When adjusting the speed adjustment screw, the o-ring friction may make the rotation of the screw difficult, but this is not abnormal.
NOTE: The speed adjustment mechanism is set at the highest speed when shipped from the factory.
