High Performance 5-20T Industrial Rail Mounted Gantry Crane

Nybon Machinery is a leader in providing overhead crane/bridge crane,gantry crane,jib cranes,ship cranes,electric winches,hydraulic winches,diesel winches,electric hoist and relative components for shipyard,automotive,material handling, specialty machinery, and workshop solutions. Our diverse portfolio also includes a wide range of lifting products for industrial, commercial and specialty applications.

The rubber-Tired gantry crane is a kind of special crane equipment, mainly used for lifting, transferring and loading the prefabricated concrete box girder in the concrete prefabricated beam field. It can also be used for the hoisting and moving of the box girder reinforcement skeleton and the inner mold of the prefabricated plant. The rubber-Tired crane can realize a variety of modes such as straight travel, diagonal travel, horizontal travel, in-situ rotation, Ackerman steering, etc.

It has mobility, flexibility, adaptability, high work efficiency, small size occupation area and do not need to lay the rail which are particularly suitable for beam factories with horizontal layout. The rubber Tired gantry crane can work independently or collaborative work by two units.

The crane mainly consists of main beam, support leg, hoisting mechanism, tire walking and braking system, steering mechanism, power system, electrical system, hydraulic system, hydraulic transmission system, cab, control system, safety device, etc.

Brief introduction of Rubber Tyred Gantry Crane?

Rubber-wheeled cranes are boom rotating cranes that use a tire-type chassis to travel. The tire-mounted crane is a kind of full-slewing crane that installs the lifting mechanism on a special chassis composed of heavy tires and axles. On the flat ground, it is possible to carry out small lifting and low-speed driving without outriggers. It consists of two parts: getting on and getting off. The boarding part is the lifting operation part, which is equipped with a boom, a hoisting mechanism, a luffing mechanism, a counterweight and a turntable, etc.; the boarding part is the supporting and walking part. The slewing bearing is used to connect the upper and lower vehicles. When hoisting, it is generally necessary to lower the outriggers, increase the bearing surface, and level the fuselage to ensure the stability of the crane.

Working level

Gantry crane is also the working level of gantry crane: it reflects the working characteristics of the crane in terms of load status and utilization.

The division of the working class is determined by the utilization class U and the load state Q of the crane. They are divided into eight levels from A1 to A8. Crane working level,

That is, the working level of the metal structure is determined according to the hoisting mechanism and is divided into A1-A8 levels.

Roughly equivalent to: A1-A4-light; A5-A6-medium; A7-heavy, A8-extremely heavy.

How to choose the right gantry crane?

Under normal circumstances, the lifting capacity is less than 50t, the span is less than 35m, and there are no special requirements for use, the single main beam type should be selected. If the width of the gantry legs is required to be large, the working speed is high, or the heavy and long pieces are often lifted, the double-girder gantry crane should be selected.
