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.
