1. General
There are two types of inspection: the frequent inspection performed by the operator and periodic inspections performed by
personnel trained in inspection and maintenance of the trolley. Careful inspection on a regular basis will reveal potentially
dangerous conditions while still in the early stages, allowing corrective action to be taken before the condition becomes
dangerous. Any deficiency revealed through inspection must be reported to an appointed person. A determination must be made
as to whether a deficiency constitutes a safety hazard before resuming operation of the trolley or hoist.
•Normal Service - that distributed service which involves operation with randomly distributed loads within the rated load
limit, or uniform loads less than 65% of rated load for not more than 25% of the time.
•Heavy Service - that service which involves operation within the rated load limit which exceeds normal service.
•Severe Service - that service which involves normal or heavy service with abnormal operating conditions.
WARNING
New and reinstalled trolley/lifter shall be inspected by a designated person prior to initial use to verify ASME B30. 17 compliance.
Inspection procedures are divided into three categories based upon intervals of inspection.
Every lift/move:Visual inspection by the operator before and during use. No written record necessary.
Visual inspection shall include:
1. Surface of the load or trolley parts for scale, grease, oil, paint, water, ice, moisture, dirt and/or coatings
2. Condition and operation of moving/functional parts
Frequent Inspection: Visual inspection by operator or designated person depending on use. Records not required.
• Inspection frequency based on use:
a) Normal service - Monthly
b) Heavy service - Weekly to monthly
c) Severe service - Daily to weekly
• Frequent Inspection shall include visual inspection of:
a) Inspect in accordance with Every Lift/move guidelines
b) Structural members for deformation, cracks or excessive wear on any part of the beam trolley
c) Loose or missing guards, fasteners, covers, stops or nameplates
d) All functional operating mechanisms for anything interfering with normal operation
e) Connection points between trolley and hoist and/or support structure in accordance with ANSI/ASME B30.17
f) As a minimum, a monthly inspection of the suspension plate, track wheels and suspension parts nuts should be
carried out
Periodic Inspection: Visual inspection by a qualified person making dated records or apparent external conditions to provide
the basis for a continuing evaluation.
• Inspection frequency based on use:
a) Normal service - Yearly
b) Heavy service - Semi-annually
c) Severe service - Quarterly
• Periodic inspection shall include visual inspection of:
a) Inspect in accordance with Every Lift and Frequent Inspection guideline
b) Loose bolts or fasteners
c) Cracked, worn or corroded parts such as trolley wheels, load shafts, or load shackles
d) Evidence of damage to body
e) Applicable labels and markings for legibility
• Equipment not in use for more than 1 month must be inspected in accordance with Frequent Inspection criteria.
• Equipment not in use for more than 1 year must be inspected in accordance with Periodic Inspection criteria.
