is supporting member by frictional

contact only. Sling must go through

hole or be safely secured over

welded track tabs when lifting track

or brace. Elevator hoist operator

must stand inside tower while

operating hoist, to avoid being under

members being raised.

loads, always operate controls

momentarily to eliminate all slack in

cable. Otherwise starting can cause

shock load, which can cause damage

to hoist or rigging.
