5 Ton - 550 Ton Box Type Double Girder Goliath Crane

Box girder design of goliath crane is mainly made of steel plate welded into box structure, which has the advantages of high safety and reliability, stiffness and other advantages, but the box girder structure of the gantry crane has the features of high cost, heavy dead weight, and relatively poor wind resistance.

Goliath cranes are also known as Portal crane or goliath cranes, which can be classified into single girder goliath crane, double girder goliath crane, engineer goliath crane, semi goliath crane, and operate on floor mounted rails.

Types of double girder goliath crane solutions are provided with capacity from 1 Ton SWL up to 800 Ton SWL (we also manufacture goliath crane designed according to client special requirement). Box type double girder goliath crane have more heavy capacity and higher work duty than single girder goliath crane.

Double girder goliath crane custom-engineered lifting solutions can be designed with two side cantilever, one side cantilever or no cantilever.

The control method could be pendent control, remote control, cabin control or both, we also can equipped adjustable seat, toughened glass for the window, fire extinguisher, air condition, acoustic alarm and interphone in the cabin.

Crane structure of box type double girder goliath crane

A Type dobule beam box girder goliath crane is mainly composed of a main beam, connecting beam, legs, ground beam, lifting trolley, cabin, and electrical control system.

Double beam box girder goliath cranes have the characteristics of high site utilization, large operating range, wide adaptability and strong versatility, and are widely used in port freight yards.

The crane designed this time is also called box girder goliath crane because the outrigger shape is similar to the letter A. The device is mainly composed of double main beams, two rigid outriggers, two flexible outriggers, saddles, upper and lower beams and other structures. The double-beam box girder goliath crane is generally made into a box structure and is often made into a double cantilever bridge. It has a closed driver's cab with adjustable seats, insulating matting on the bottom plate, and tempered glass for window glass, and it may be equipped with heating and cooling air conditioners, buzzers, walkie-talkies, and other items as needed. Cable reel and high-altitude sliding line are the two types of power supply.

Main crane parts & components of box type double girder goliath crane

• Trolley operating mechanism -It is mainly composed of a lower beam and a trolley. The trolley is composed of a driving wheel group and a driven wheel group. The running mechanism includes components such as a motor, a reducer, a gear, and a wheel group.
• Outrigger-The section steel is used as the material, and then welded into a cage structure, the lower end is connected with the lower crossbeam, and the upper end is connected with the main beam bolts through a flange.
• Driver's cab-The frame is made of section steel, and the outer shell is welded on the frame with thin steel plates. The cab is closed with a broken line. The electrical appliances, power distribution cabinets and lines of the operating mechanism are generally located in the cab.
• Main beam-Shaped steel and steel plates are welded together, usually welded into a triangle shape, and on the main beam, there are also trolley running rails.
• Trolley operating mechanism-The main components are similar to the running mechanism of the trolley. The electric motor is driven by the reducer, and the small gear on the reducer is transmitted to the large gear so that the trolley can travel back and forth.
• Lifting mechanism-It is installed on the trolley frame and realizes the lifting movement through the hoist and the matching fixed pulley, movable pulley or hook.

Features of box type of double girder goliath crane

• The double main beam goliath crane has a strong carrying capacity, large span, and good overall stability
• The use of steel plates welded into a box structure has the characteristics of high safety and high rigidity.
• Standardization, serialization, and generalization of parts and components.
• The box-shaped double beam welding structure is adopted to increase the working space and facilitate transportation, installation, and maintenance.
• The driver's cab has a wide field of vision, with a linkage console inside, which is flexible, stable and comfortable to operate. Fans, heaters, air coolers, air conditioners, walkie-talkies, etc. can also be added according to user requirements.

Application of box type double girder goliath crane

Box type double girder goliath cranes are suitable for loading and unloading in open-air warehouses, stockyards, railway freight stations, ports and wharves. It can also be equipped with a variety of special hooks for a variety of special operations.

The normal operating environment of this system crane should be within the range of -25℃～+40℃, and the average temperature within 24 hours should not exceed ten 35℃. The altitude of other installation and use locations should not exceed 2000 meters, and the motor capacity should be checked if it exceeds 1000 meters.
