Hoist Service

• Normal Service—yearly
• Severe Service—monthly to quarterly
• Special Service—as recommended by a qualified person
•  
• Intervals between inspection should never exceed one year. Written records are not required for frequent inspections, however written records should be kept. The WSTDA, RS-1 and ASME B30.9 require written record of the latest inspection.

• All inspections shall be performed by a designated person per the manufacturer’s recommendations and with the requirements of ASME B30.21. Any deficiencies identified shall be examined and a determination made by a qualified person as to whether they constitute hazards and whether a more detailed inspection or disassembly is required.

• Excessive component wear, cracks, distortion, warping, or other internal damage — or any other part that displays indications of potential failure — will be noted by the inspector. Based on that assessment, the hoist may be deemed beyond reasonable repair, and replacement is recommended.

• Customers can come to one of our shops across the country or we can come to you with our Mobile Testing Unit. Technicians at Hercules SLR are trained and certified with LEEA accreditation. All inspections are completed within ASME standards.
