Use Lifting Equipment Safely
!
WARNING
• Always use a lifting device with a lifting capacity
greater than the weight of the item being lifted.
• Secure the load to the lifting device using cables,
chains, or slings rated to handle the load being lifted.
Fasteners being used to connect lifting devices must
be strong enough to handle the load. Also be sure
the mounting point of load is strong enough to handle
the load.
• When using a lifting device, always connect the load
so it is balanced.
• Always use a lifting device on a hard, level surface.
• Lower the lifting device to the lowest point before
moving. Move the load slowly.
• Always support the load as soon as possible; never
leave a load suspended in mid-air.
