User Manual for VEVOR 3T*1.5M Lifting Slings Straps

Quick Guide

This document provides essential instructions for the safe operation and maintenance of the VEVOR 3T*1.5M lifting slings. Always inspect the equipment before use, adhere to the rated load limits, and ensure the lifting angle is appropriate for the load.

Safety Instructions

WARNING: Failure to follow these instructions can result in serious injury.

• Read the manual thoroughly before use.
• Do not twist or knot the sling rigging.
• Do not drag the sling when the lifted object is pressing on it.
• Strictly adhere to the rated load to prevent rope breakage and accidents.
• No one is allowed to stand under the heavy object or within the swing area during hoisting.
• Personnel must wear safety helmets and gloves.
• Perform weekly (or every 50 hours of work) inspections for broken or worn suspension belts. Replace if thickness decreases by more than 20%.
• Inspect hooks for deformation, cracks, or looseness. Stop using immediately if abnormalities are found.

Installation and Commissioning

1. Check that lifting straps are undamaged, hooks are not deformed or cracked, and connection parts are secure.
2. Securely attach the lifting rings to the crane or hoist hook.
3. Perform a no-load trial operation: Start the hoisting equipment, operate to open/close and lock/unlock. Ensure operation is smooth and balanced. Stop immediately if there is jamming or abnormal noise.
4. The angle between the sling and the horizontal plane is recommended to be greater than 45°.
5. Simulate the lifting operation with standard weight testing. Raise the object 1-2 meters, hover for 3-5 minutes, and check component condition. Make adjustments if necessary.

Operation

1. Preparation: Clear the site of obstructions and verify that the lifting equipment capacity matches the total weight of the rigging and load.
2. Connection: Connect the split-leg hook to the heavy object lifting point and lock it. Connect the main lifting ring to the lifting equipment and lock the opening.
3. Lifting: Activate the equipment slowly to ascend at a constant speed. Maintain stability and avoid sudden stops or vibrations. When reaching the target area, descend slowly and gently. Once stable, release the hook and retrieve the rigging.
4. Cleaning: Clean the rigging, inspect the condition of slings, hooks, and connection points. Apply anti-rust treatment (e.g., anti-rust oil on hooks) and store properly.

Maintenance

• Do not exceed the Working Load Limit (WLL).
• Store in an environment away from chemical substances.
• Storage temperature range: -40°C to 100°C.
