Harrington Hoists and Cranes UBC-Universal Beam Clamp - Manual (Page 5)

5.5 Periodic Inspection
5.5.1 Inspections should be made on a PERIODIC basis in accordance with Table 5-5, “Periodic Inspection.” Evaluation and resolution of
the results of PERIODIC Inspections shall be made by a designated person such that the clamp is maintained in safe working
condition.
5.5.2 For inspections where load suspension parts of the clamp are disassembled, a load test per ANSI/ASME B30.20 must be performed
on the clamp after it is re-assembled and prior to its return to service.
Table 5-5 Periodic Inspection
Requirements of frequent inspection.
Evidence of loose bolts, nuts, or rivets.
Evidence of worn, corroded, cracked, or distorted parts such as clamp handles, screws, pins, bushings, snap or spiral
retaining rings, spacers, nuts, and suspenders.
Evidence of damage to supporting structure.
Function label on clamp for legibility.
Warning label properly attached to the clamp and legible.
5.6 Inspection Methods and Criteria
5.6.1 This section covers the inspection of specific items. The list of items in this section is based on those listed in ANSI/ASME B30.20
and ANSI/ASME B30.16 for the Every Lift, Frequent and Periodic Inspection.
5.6.2 Every Lift Inspection – Performed by the operator before and/or during every lift. Not intended to involve disassembly of the clamp.
Disassembly for further inspection would be required only if every lift inspection results so indicate. Disassembly and further
inspection should only be performed by a qualified person trained in the disassembly and re-assembly of the clamp.
5.6.3 Frequent Inspection - Not intended to involve disassembly of the clamp. Disassembly for further inspection would be required only
if frequent inspection results so indicate. Disassembly and further inspection should only be performed by a qualified person trained
in the disassembly and re-assembly of the clamp.
5.6.4 Periodic Inspection - Disassembly of the clamp is required. Disassembly should only be performed by a qualified person trained in
the disassembly and re-assembly of the clamp.
Table 5-6 Clamp Inspection Methods and Criteria
Item Method Criteria Action
Functional
operating
mechanisms. Visual Mechanisms should function properly. Components should not be deformed,
scarred or show significant wear. Clamp screw threads should be free from
significant wear. Repair or replace
as required.
Mechanical and
Lifting System –
Components Visual, Function Clamp components including clamp handles, suspenders, spacers, bushings,
snap or spiral retaining rings, and pins should be free of cracks, distortion,
significant wear and corrosion. Evidence of same can be detected visually. Replace.
Bolts, Nuts and
Rivets Visual, Check
with Proper Tool Bolts, nuts and rivets should not be loose, deformed or corroded. Tighten or
replace as
required.
Warning Labels Visual Warning Labels should be affixed to the clamp and be legible. Replace.
Clamp Capacity
Label Visual The label that indicates the capacity of the clamp should be legible and securely
attached to the clamp. Replace.
6.0 Maintenance
6.1 For clamp maintenance or storage, comply with the following points.
6.1.1 CAUTION
 Possibility of corrosion on components of the clamp
increases for installations where salt air and high
humidity are present. Make frequent and regular
inspections of the clamp’s condition and operation.
 Do not store the clamp while supporting a load.
 Remove any dirt or water on the clamp.
 Store the clamp in a dry and clean area.
 Perform all inspections given in “5.0 Inspection” if
irregularity of the clamp is found after operation.
6.2 Disassembly/Assembly
6.2.1 When re-assembling the clamp, refer to parts list figure in Section 8.0 for the proper component placement and orientation.
