20 ton gantry cranes for sale Philippines 

Double girder gantry crane is specially designed for heavy cover lifting and machinery maintenance, and other loads handling.

Basic parameters of 20 ton double beam gantry crane:

• Capacity: 20 Ton
• Lifting Height: 3 M
• Span: 11 M
• Lifting Speed: 3.6 M/Min
• Crane Travelling Speed: 20 M/Min
• Control Method: Pendent Control

Features of 20 ton gantry crane for Philippines

The double beam gantry cranes are equipped with double trolleys. Each trolley is equipped with 2 hooks, and all together 4 hooks, which can be operated at the same time. This gantry crane hook has the function of synchronized lifting and lowering to meet the stable lifting and landing of the long loads and heavy objects.

Types of Gantry cranes for sale Philippines

According to different standards, gantry cranes can be grouped in to different types. Generally the types of gantry cranes are as following:

• Full-gantry cranes: The gantry cranes have two supporting legs that running on the gantry rails, embeded on the ground.
• Semi-gantry cranes: The gantry cranes has one single leg running on the ground beam and the other end is mounted and Travelling along the rail supported on the structure or facilities.
• Cantilever gantry cranes: The cantilever refers to the outreach of the gantry crane span, which enables the hoist trolley moves beyond the gantry legs and enlarges the covering area of the gantry crane. Double cantilever gantry crane are the most common form of structure, its structural force and the effective use of the site area are reasonable.Single cantilever gantry cranes is often chosen by site constraints.
• Single girder / double girder gantry crane :The single girder / double girder gantry cranes refers to  the number of the crane girders, which is largely determined by the load capacity. For lighter loads, the single girder gantry is used and otherwise, the double girder gantry is better.
• Box girder gantry crane: Usually refers to the structure of gantry crane, which is made of steel plates , constructed into box shaped structure to provide high strength for large loads handling. It is widely used compared with truss girder types.
• Truss girder gantry crane: It refers to the gantry girder is made of steel bars, which are welded together to provided high wind resistance, usually used for outdoor application.

 

Truss crane v.s. Box girder

• Truss gantry crane -The structural form welded by angle steel or I-beam has the advantages of low cost, light weight, and good wind resistance. However, because of the large number of welding points and the defects of the trusses themselves, the truss beams also have the drawbacks of large deflection, low rigidity, relatively low reliability, and frequent detection of welding spots. Suitable for sites with low safety requirements and low lifting weight.
• Box girder gantry - The use of steel plates welded into a box structure, with high safety, stiffness and other characteristics. It is generally used for gantry cranes with large tonnage and oversized tonnage. As shown in the right figure, MGhz1200 has a lifting capacity of 1,200 tons and is the largest gantry crane in China. The main beam adopts a box girder structure. The box girder also has the disadvantages of high cost, heavy self, and poor wind resistance.

Rail mounted gantries vs. Rubber tyred gantry cranes

• Rail mounted gantry crane is used for transferring heavy loads, manually or motorized, over a fixed route.
• Rubber tyred gantry cranes is widely used for outdoor application with high flexibility. The rmg gantry cranes can be moved from one working site to another very easy.

Fixed height vs. Adjustable height

• Fixed height portable gantry crane is flexible, which can be replaced and relocated, which is featured as fast, easy movement to and from a work site.
• Adjustable gantry crane is designed with telescopic height, which can be used to meet various lifting requirement and application conditions.

Steel gantry vs. Aluminum gantry

• The steel gantry crane can be used for heavier loads handling  with capacity up to 10 tons. With customized design, the steel gantry cranes can be used for loads handling with capacity up to 20 tons.
• Aluminum gantry cranes is for light loads handing with capacity up to 2 ton and 3 ton. For being light weighted, the aluminum gantry cranes are very handy to use.

Gantry cranes are widely used  in large docks, ports, shipyards, and other places. According to their structural characteristics, gantry cranes are divided into many types, and each type of gantry crane has its unique characteristics. features and suitable applications. No matter which industrial sectors or applications of loads handling, Yuantai Cranes is able to provide the customized gantry crane for your application.
