When the two limbs rigging link vertical lifting clamp with a steel plate with universal style rings angle less than 60 degrees, no universal style rings angle less than 30 degrees, and two hanging clamp the maximum lifting load shall not exceed 1.5 times alone. Vertical hanging clamp plates only for vertical lifting, prohibited the use of the horizontal lifting steel plate. After lifting the plate if serious tilt, you should re-install vertical clamp. Lifting process, steel is prohibited by the collision and impact, lifting process should try to maintain a balance, double beam grab crane the following non-stop people or goods passed over the surface of the steel plate was hanging site does not allow oil.
