Level Luffing Crane

Level luffing crane is a commonly used portal crane. It is widely used in ports, shipside, stations and storage yards, providing extremely high material handling efficiency. Nowdays, it has been an indispensable port crane or shipyard crane, characterized by compact structure, high efficiency, great stability, comfortable operation, safety and reliability, easy maintenance and striking appearance.

The level luffing crane is especially suitable for use in general purpose ports where it serves as highly popular container handling crane, ensuring low cost of investment but amazing efficiency in handling containers, sundries and bulk materials.

Zhonggong offers 5 types of level luffing cranes which come with hooks and grab buckets. They offer various lifting capacities according to the operation demands.
