Page 3 brand lifting clamps are energy-saving lifting equipment which have been developed for the purpose of transporting steel materials. Proper use Operate lifting clamps after carefully reading and understanding this instruction manual for enhancing efficiency and safety of operation. Prime efficiency and economy Advanced functions, reasonableness and versatile applications of finely and carefully designed lifting clamps ensure...
Page 4 Precautions for safety operation (Pages 1〜10 are comon to all lifting clamp models) Be sure to read this instruction manual carefully before use. Mistaken use of lifting clamp may cause a danger such as dropping of load. Education of “crane safety regulations,” “operation manual for lifting clamp,”...
Page 5: Check Before Operation
1. Handling in general WARNING ● Do not operate until the contents of the operation manual, and caution tag/plate are thoroughly read and understood. ● Do not operate without a legal qualification. ● Be sure to clear of the area of the operation for lifting or turning a load against possible drop off or fall over.
Page 6: Lifting Operation
3. Lifting operation WARNING ● Do not use clamp, lifting at one point. (excluding special or custom ordered products) ● Do not use the clamp in the following ways of lifting: lifting of two or more individual objects at one time. (overlapped loads, padded load etc.
Page 7 ● Stop the lifting operation by crane for a moment when the load is applied to the lifting ring for safety checking. (depth of the load into the clamp opening; status of locking). ● Stop the operation of the crane just before the load reaches the ground, and check the following matters: (Inclination or Instructed falling over of the load and security around the landing area...
Page 8 ■ General warning for use (comon to all lifting clamp models) Be sure to select proper model clamps for use. Pay special attentions to keep the lifting direction (rope angle). Confirm the weight of the load. Do not exceed maximum capacity (designated ton) on clamps.
Page 9 Never lift two or more steel plates or steel members at a time. The load may move to an unexpected direction when lifted off the ground and as such confirm the center of gravity and the clamping posi- tion for safety when raising. Sufficient caution should be taken until the clamp with the load becomes completely balanced.

■ Maintenance and Inspection 1. Maintenance Daily maintenance is important for efficient and safe operation even under the severe use condition and for such purposes, please comply with the followings. (1) Designate the use standards and control. (2) Keep clamps indoor and do not leave them outdoor. (3) Check the followings to maintain in a good condition.

■ How to use 1.OPERATION METHOD Screw tightens when turned clockwise, and loosens when turned counterclockwise (Right screw). When installing clamps, insert a lifting load completely until it comes in contract with the deepest of the jaw opening of Body and set in a manner that the entire circumferential teeth of inner portion of concen- tric rings touch the surface of the load.
Page 18 2. OPERATION PATTERNS ① When lifting at 2 points, keep the lifting angle within 60°. Within 60° Within 60° Keep the lifting angle within 60°between ropes. ② Always lift at 3 or more points with complicated shaped objects. (For horizontal lift, always lift at 4 points when lifting a steel plate positioned horizontally to a floor level) Within 60°...
