Tongs for lifting ingots Mechanical or electro-hydraulic drive.
MECHANICAL SYSTEM: operation based on a ever mechanism. Gripping and releasing the of the part is made possible by a rotating mechanical system that allows the tong to open and close. Rotation of the pawl is obtained mechanically every time the tong rests on the component to be lifted
ELECTRO-HYDRAULIC DRIVE: the tong works mechanically but the closing speed of the levers is regulated by a hydraulic unit that drives a cylinder with the task of exerting a force opposing the spontaneous closure of the levers. Correct adjustment of the hydraulic system allows fluid, accurate and above all safe closure movement.
