3. SEQUENCE OF OPERATIONS FOR DYNAMIC HOIST LOAD TESTER
IMPROPER test stand use could result in death or serious in
jury.
To avoid these hazards:
NEVER overload unit.
ALWAYS operate, inspect and maintain this test stand with
operator safety as a goal.
ALWAYS read owner's manual and safety instructions prior to
use.
3.1 The following is a suggested procedure for load testing an electric operated
hoist.
Step 1: If the hoist tester is mounted on casters,
insure that the caster pivot and rolling locks
are engaged.
Step 2: Always use the winch to lift heavy units into place.
Step 3: Using the hoist tester winch and hoist tester step, suspend a 1/4 to 5 ton hoist
from front top link (yellow, size 1) or 6 to 10 ton hoist from the rear top link
(orange, size 1 1/4).
Step 4: If the hoist is a Harrington ES series hoist, select the cord assembly with 5P
plugs on both ends. Next plug the one 5P plug into receptacle on the electri-
cal enclosure on the hoist test stand and the other 5P plug into the area
where the pendant plug is normally inserted at the lower portion of the electri-
cal enclosure of the hoist.
