WARNING
•
Personnel hearing can be permanently damaged if exposed to constant high noise
levels of 85 dB or greater. Wear approved hearing protection devices when
working in high noise level areas. Personnel exposed to high noise levels shall
participate in a hearing conservation program in accordance with DA PAM 40-501
(WP 0131). Hearing loss occurs gradually but becomes permanent over time.
•
Never use hoist winch with less than five wraps on the drum. Failure to comply
may result in hoist winch cable coming loose from drum.
•
All personnel will stay clear (at least double the length of cable used) during the
wire rope testing. Cable could snap resulting in personnel death or injury.
Personnel inside vehicle must operate winch with hatches closed.
•
Ensure all safety pins and bolts are in place and secure prior to lifting.
•
Never grasp cable close to stationary objects. Sudden movement of cable could
injure hands. During lifting operations, ensure lifting vehicle's transmission is in
Park (P) and brakes applied to prevent possible injury to personnel.
•
If track under #6 roadwheels loses ground contact with a load of an excess of
vehicle's capacity lower load immediately. Failure of the hoist winch may occur,
causing it to free fall.
•
Wire ropes can become entangled, frayed, or contain broken wires. Wear heavy
leather-palmed gloves when handling wire rope. Do not allow moving wire rope to
slide through hands, even when wearing gloves. Failure to comply may result in
personnel injury.
•
Do not lift loads at an angle of more than 3 degrees from center.
•
Failure to comply may result in personnel death, injury, and/or damage to
