Operating Instructions
Changsha Jieding Lifting Machinery Co., Ltd. provides a practical inspection checklist for lifting clamps and rigging covering pre-use, during-operation and post-use checks — including appearance, connection points, locking mechanisms, load status, working range and abnormality handling — to help distributors, project owners and end users standardize safe operation in line with model-specific instructions and site safety rules.
Pre-Use and On‑Site Inspection Checklist for Lifting Clamps and Rigging
This practical checklist from Changsha Jieding Lifting Machinery Co., Ltd. is designed to help distributors, project owners and end users standardize pre‑use, during‑operation and post‑use inspections of lifting clamps and associated rigging. Use this as a quick reference alongside each product’s model‑specific manual and your site safety procedures.
Scope & Applicability
Applies to manual and mechanical lifting clamps, plus basic rigging components used in lifting operations (hooks, shackles, slings, spreader beams). Not a substitute for equipment-specific inspections, statutory inspections or manufacturer maintenance schedules.
How to use this checklist
- Perform pre‑use checks before every lift or start of shift.
- Monitor critical items during operation and stop if unsafe conditions appear.
- Record findings and follow abnormality handling procedures immediately.
Pre‑Use Inspection (Before each lift)
- Appearance: Check clamp body, jaws and load paths for cracks, deformation, excessive wear, corrosion or missing parts.
- Markings: Verify rated capacity, serial/model number and CE/other applicable markings are present and legible.
- Connection points: Inspect swivel joints, pins, bolts, shackles and hooks for proper fit, free rotation where designed, and absence of elongation or damage.
- Locking & release mechanisms: Confirm locking latches, safety catches and release controls operate smoothly and fully engage.
- Jaws/gripping surfaces: Ensure contact surfaces are clean, undamaged and appropriate for the load material (no oil/contaminants that reduce grip).
- Compatibility & rigging layout: Verify the clamp type and rated capacity match the planned lift, and rigging geometry keeps load within the clamp working range.

During Operation — On‑Lift Monitoring
- Attachment integrity: Observe for slippage, shifting or unexpected rotation of the clamp on the load.
- Load behaviour: Watch for abnormal deformation, unexpected movement or changes in center of gravity while lifting.
- Audible and visual cues: Stop if unusual noises (creaks, bangs) or visible defects appear.
- Working range: Ensure lifting stays within the clamp’s rated working range and avoid side pulls unless permitted by design documentation.
- Environmental hazards: Monitor for temperature extremes, corrosive atmospheres or other site conditions that may affect clamp performance.
Post‑Use Inspection & Handling
- Visual check: After use, re‑inspect for new damage, wear, bending or contamination.
- Clean & protect: Remove debris, lubricate moving parts if specified and store in a dry, designated location.
- Tagging: Mark clamps that require maintenance or have been withdrawn; keep them segregated from serviceable stock.
- Record keeping: Log daily findings, any load incidents and maintenance actions for traceability and compliance.
Abnormality Handling — Immediate Steps
- Stop the lift and secure the load in a safe position.
- Isolate and tag the affected clamp or rigging component.
- Report details (time, operator, load, symptom) to site safety officer and equipment owner.
- Do not attempt field repairs beyond simple isolation — arrange inspection by qualified maintenance personnel or manufacturer representative.
Always follow the product‑specific manual and site lifting plan. If in doubt about suitability or condition, do not proceed with the lift.
Selection & Verification Tips for Distributors and Project Owners
- Match clamp type to load geometry: Plate clamps, lifting hooks or beam clamps differ in grip method and permitted orientations—select per manufacturer guidance.
- Confirm rated capacity and safety factors: Ensure rated capacity covers the load and any rigging inefficiencies; verify markings and documentation at receipt.
- Request manufacturer traceability: Keep model, serial and test/certification records accessible for each unit in service.
Documentation & Records
Maintain simple logs per unit that include:
- Pre‑use inspection date/time and inspector initials
- Any issues found and corrective actions taken
- Dates of formal inspections, load tests and repairs
Tip: Combine daily pre‑use checks into a simple checklist sheet or mobile form to ensure consistency and ease of audit.
