LOAD TESTS
After creating a RECORD OF SATISFACTORY CONDITION and before using the lifter for the first time, a
qualified person should conduct a load test. The test load should be 125% of the capacity of your clamp. For
example, the test load for an CPC-20 clamp is 2,000 x 1.25 = 2,500lb. (1136.4kg). Elevate the test load a few
inches above the ground for approximately 1 minute. Ground the load and disconnect it from the plate clamp.
Perform a
Monthly Inspection as described in INSPECTIONS AND MAINTENANCE (below). The (qualified)
person performing the test must compose a written report confirming the load rating of the clamp. The load rating
(capacity) should not be more than 80% of the test load. The clamp must undergo load testing whenever it is
repaired. Never modify the clamp.
INSPECTIONS AND MAINTENANCE
Regular inspections and maintenance are essential. Always inspect and maintain this product
in accordance with the instructions in this manual.
Apply all relevant inspection instructions in your copy of ASME B30.20 as well as the following instructions.
Inspections and maintenance should only be performed by qualified persons. Compare the results of each
inspection to the RECORD OF SATISFACTORY CONDITION
. Do not use the clamp unless all parts are in
satisfactory condition. Replace parts that are not in satisfactory condition before returning the clamp to service.
Only use manufacturer-approved replacement parts to restore the unit to satisfactory condition. DON’T GUESS! If
you have any questions about the condition of your clamp, contact the
TECHNICAL SERVICE department.
The phone number is provided on the cover page of this manual. Never make temporary repairs of damaged or
missing parts.
I. Disconnect the clamp from the hoist hook and tag it “Out of service”.
II. Perform the appropriate inspection. If a component is not in satisfactory condition, repair it or replace it as
necessary to restore the unit to satisfactory condition. DO NOT modify the clamp.
A. Inspection before each use – The operator must inspect the clamp before every lift. Closely inspect all
parts of the chain, pear link, shackle link, and link arms for cracks, elongation, warps, and other forms of
damage. Remove debris, grease, oil, etc. from the clamp surfaces. Check the gripper teeth. Teeth must be
sharp and free of foreign material.
-OR-
B. Monthly inspections – At least once per month a qualified person must perform the following inspections
and maintenance. Written reports should be prepared for every monthly inspection including inspections
following
LOAD TESTS.
1. Surfaces: Look for forging fractures, weld fractures, significant wear, and deformations/distortions,
corrosion/rusting, and metal fatigue. If rusting is purely superficial, remove it with a steel bristle brush or
steel wool. Clean the affected area and apply touchup paint. If rusting, rot, or thinning has weakened the
material, permanently remove the clamp from service.
2. Throat opening: Measure the width of the throat opening in the 3 places that were measured to
generate the RECORD
. Enlargement of the opening indicates that the clamp has been overloaded. The
clamp must be permanently removed from service.
3. Gripper/cam, gripper teeth, and pad: Examine the gripper teeth. If teeth are flattened by 50% or more,
replace both the gripper and the pad. If the plate clamp is used to only move sheets of a particular
thickness, the gripper surface will wear in only 1 area and will have to be replaced more frequently.
4. Spring, lock, and pad: The spring should hold the gripper/cam against the pad when the clamp is
unloaded. The locking spring should provide little initial pressure (of the gripper) without material in the
clamp. Counter-pressure should increase as the gripper is pushed away from the pad. The lock lever
should rotate freely.
5. Pins and pinholes, and other fasteners: Examine all pins and pinholes. Pins should be straight.
Pinholes should be round, not ovoid. Evaluate the degree of wear of all pins and pinholes. Examine pin
retaining clips and spring pins (used to secure pins in place).
6. Chain assembly: Measure the length and width of each chain link, the pear link, and shackle link. Make
sure the measurements match the measurements in the RECORD
. If any cracks, distortions, elongation,
or severe wear is found, permanently remove the clamp from service. Examine the intermediate link arm
and link arm for distortion, cracks, and severe wear.
7. Labels: Check all labels. Labels are shown in the LABELING DIAGRAM (below). Replace labels that
are missing, damaged, or not easily readable.
