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 LPC-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 lifter, 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 (A or B). 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 the bale mechanisms. Check the bale loop and bale pin for cracks, elongation, warps, and
other forms of damage. Confirm that the bale mechanism is securely pinned in place. Remove
debris from the clamp surfaces. Check the gripper teeth. Teeth must be sharp, clean, & dry.
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 & apply touchup paint.
If rust, 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 mechanisms, 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
pressed away from the pad. Lock and unlock the clamp. Confirm that the lock engages and
disengages satisfactorily.
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. Bale assembly: Measure the length and width of the bale opening and connecting 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.
7. Labels: Check all labels. Labels are shown in the LABELING DIAGRAM (below). Replace labels
that are missing, damaged, or not easily readable.
