Model 230B Lifting Frame
92-1052 : Orig. 021204
OPERATION
A two-speed, reversible, hand-held drill motor is used power the lifting device. At-
tached to the drill motor is a 3’ extension with a 1/2" deep-socket. This assembly is
held by the operator, who uses the on/off trigger switch, forward/reverse switch, and
low/high-speed switch to control the motion of the lifting device. A hand crank is
attached to the rotator mechanism to enable changing the orientation of the 230B. A
swing-energized locking pin holds the hand crank in position. The pin must be
manually pulled out to disengage the lock, allowing the hand crank to be turned.
CAUTION: The locking pin must be engaged whenever the hand crank is not in use
to prevent uncontrolled rotation of the 230B.
To perform a lifting or lowering operation, the operator sets the drill motor to the
desired speed and direction and engages the 1/2" socket over the 1/2" hex protrud-
ing from the bottom of the center pulley assembly. The drill motor is then energized,
causing the pulleys and timing belts to rotate the two acme screws, resulting in lifting
carriage motion. CAUTION: The lifting carriage should not be allowed to run to its
hard-stops at either end of its travel. Carriage motion should be stopped once it
reaches the area marked with caution tape.
