hitachi — Precautions for Disassembling and Assembling

GENERAL / Precautions for Disassembling and Assembling Precautions for Using Nylon Sling 1. Follow the precautions below to use nylon slings safely. Attach protectors (soft material) on the corners of the load so that the nylon sling does not directly contact the corners. This will prevent the nylon sling from being damaged and the lifted load from slipping. Lower the temperature of the lifted load to lower than 100 ° C (212 ° F). If unavoidably lifting a load with a temperature of 100 ° C (212 ° F) or more, reduce the load weight. Do not lift acid or alkali chemicals. Take care not to allow the sling to become wet. The load may slip.

When required to use more than one sling, use slings with the same width and length to keep the lifted load balanced. When lifting a load using an eyehole, be sure to eliminate any gaps between the sling and load. (Refer to the right illustration.) Reduce the load weight so that it is less than 80 % of the sling breaking force. Avoid using twisted, bound, connected, or hitched slings. Do not place any object on twisted or bent slings. (Refer to the right illustration.) When removing the slings from under the load, take care not to damage the nylon slings. Avoid contact with protrusions. Avoid dragging slings on the ground, throwing slings or pushing slings with a metal object.

When using with other types of slings (wire rope) or accessories (shackle), protect the joint so that the nylon sling is not damaged. Store the nylon slings indoors so they won’t dete- riorate with heat, sun light, or chemicals.
