Section III. TECHNICAL PRINCIPLES OF OPERATION

TM 55-1730-223-13

1-8. TONGUE.

The tongue steers the front wheels and allows the

operator to move the platform into position more easily. The tongue

can be removed when the platform is in position.

1-9. WHEELS. The wheels swivel or can be locked to roll in one

direction.

This allows the operator to move the platform sideways to

get it close to the work. Movement of the platform can be stopped by

hand operated brakes on the front wheels. The platform can be

immobilized by jacking the wheels off the ground, using the

immobilizing jack handles located at each corner of the frame.

1-10. JACKSCREWS. The jackscrews are positioned by means of a

handwheel and support the load of the platform. No additional locking

is required.

1-11. STATIC DISCHARGE REEL. After the platform is positioned and

immobilized, the static wire is pulled from the reel and attached to an

earth ground by means of alligator clips. After use, the static wire

is returned to the reel.
