Specification :

1. Instructions for lifting: (1) Aim the pin of lifting device at the ear of the steel structure. (2) Insert the pin into the hole of the bottom. When " click " sound is heard, it means the protection device is closed. (3) Pull the wire of the pin again to assure the protection device is secured. (4) Start lifting after completing the procedure above. 2.

(4) Repeat the same procedures above on the next job. 3. Features of safety lifting devices: (1) The imported alloy material is made of hot forging. The anti-strength is five times stronger more than rated load. (2) Loading pin and lifting bolts are both made of imported specialized alloy. The anti-shear is five times more than rated load. (3) The 5 T lifting device and guide-way are made by hot forging, compact size, light-weighted and convenient to operate. (4) Attached with special auxiliary ring ears on lifting bolts, greatly prolong serving life and increase anti-shear.
