Note: This eccentric boom crane is designed according to the customer's working environment. Its main parameters depend on the specific situation and can be customized. For details, please consult our sales staff.
Features
Eccentric Boom: The most distinctive feature is the eccentric boom, which can extend the crane's working range. For example, some eccentric grab cranes may have a 10-meter eccentric boom2.
Rotating Mechanism: A rotating mechanism allows the boom to rotate horizontally, increasing the operational flexibility.
Grab Device: This is usually used in conjunction with grabs like clamshell grabs or orange peel grabs. The grab is an automatic material handling device, and the crane operator controls its opening and closing actions.
Our FEM Analysis of the Eccentric Boom Crane
Working principle
The cargo crane controls the pitching motion of the lattice-type jib through wire ropes, pulley blocks, and the drive system to lift and lower the goods. It also controls the horizontal movement of the goods through the slewing mechanism to realize the goods' turning.
