Electric Powered Vacuum Lifter Inspection Report
This procedure serves as a guide for evaluating the condition and safety of the lifter. It addresses common issues and includes specific checks for cleanliness, filter condition, label legibility, electrical components, vacuum pump performance, and structural integrity.
This inspection report is intended solely as an aid to remind inspectors of the most frequently occurring lifter problems. It does not cover every problem that can occur. The inspector must be alert for any other conditions that could affect safe use of the equipment. For safety requirements, including the user's responsibilities for testing, inspecting, and maintaining the lifter, please refer to the American National Standard Institute (ASME) B30.20 Safety Standards, Chapter 20-2: Vacuum Lifting Devices.
General
Cleanliness- Lifter must be clean enough to observe condition and read gauges. Lifter should be free of dirt or debris, which could affect safe operation.
Filter- Inspect clean or replace filter.
Labels- All Labels must be legible. Load capacity: Entire lifter, each crossarm each pad. Operating instructions, Safety Rules, Warnings, Tighten Slides warnings.
Electrical Generators
Power Cord & Plug- Check for loose wires or damaged insulation.
Lifter Remote- Check to make sure labels are legible, Check for loose wires or damaged insulation.
Vacuum Pump- Observe condition, running noise, -Check pump-down time, max. vacuum level, Frequent cycling with ball valves closed.
Vacuum Loss Sensor (VLS)- Operate test switch for light and horn. General condition of display clarity.
Reservoir- With power off hold and clean, smooth non-porous load for: 10 min. with max 1.0 in. hg vacuum drop. Per ASME Safety Standards.
Structural
Welding- Check for cracks, corrosion, deformation fatigue. Check welds and adjacent metal for signs of cracked or spalled paint indicating "working" of the metal.
Frame- Check the items below for damage: bent, broken or missing parts; adjustability or distortion.
Main Beam
***Important*** Cleanliness and condition of Rubber Cups and Pads
Cups/Pads- Check for cuts, tears, wear, aging (cracks, crazing or hardening of the rubber), embedded dirt or chips, and inner seal condition.
Crossarms
Lifter Operation Lift Test - Lift a clean, dry, smooth, non-porous load, preferably weighing the maximum rated lift capacity. Operation should result in a clean, smooth lift. All gauges and indicators should be visible to the operator and work normally. Watch and listen for: - Drop in vacuum level - Vacuum leaks - “Sticky gauge” or failure to return to zero - Unequal pad loading/unequal spring compression
Attach Time: in seconds
Release Time: in sec.
Slides
Pad Suspension
Brackets, Attachments
Parking Stands Handles
Fasteners- Check condition and tightness of all fasteners, hand knobs and wing nuts. Cleanliness and condition of rubber.
Hoses and Connections- Check for cracks, wear or abrasion especially near connection, and cracked or damaged fittings.- Check tightness of all hose clamps - Check for collapsed or kinked vacuum lines
Ball Valves- Check operation, condition, broken or missing handles, labels
Filter Housing- - General condition, breaks or dents, and cover condition of all seals.
