1. The steel coil spreader is mainly composed of lifting concrete and counterweight iron.
(1) Lifting specific: the main part of the steel coil spreader is made of steel plates (high-quality low-alloy steel) and steel pipes. The cross-section is a box structure, which has good bending and torsion resistance. The spreader is lightweight and easy to use. long life.
(2) Counterweight iron: It plays the role of adjusting the balance of the spreader, so that the center of gravity of the spreader and the suspended object are in a line.
2. Daily maintenance and maintenance of steel coil spreader
(1) The used steel coil spreader must be placed on a special shelf, stored in a ventilated, dry and clean workshop, and kept by a special person.
(2) The surface of the steel coil spreader should be protected against rust frequently, and it is not allowed to be stored in acid, alkali, salt, chemical gas and humid environment.
(3) Steel coil spreaders are prohibited to be stored in high temperature areas.
(4) Clean the rotating parts regularly and apply lubricating oil regularly to prevent dry friction and jamming.
