450T Lifting Beam Double Girder Gantry Crane 380V For Bridge Construction

Product description

450T Lifting Beam Gantry Crane provided by Henan Mine Crane for bridge construction

Lifting beam gantry cranes can be used to lift two-piece prefabricated beams at the same time, and a single gantry crane equipped with double hoisting equipment to lift prefabricated beams separately. The lifting capacity of two lifting machines at the same time is generally 450 tons, and the lifting capacity of a single lifting machine. The weight is usually up to 900 tons.

Lifting equipment, which can achieve all-round mechanized action. It is mainly used to lift the prefabricated beam from the beam-making platform to the beam storage platform.

After the prefabricated beam is completed, it is lifted from the beam-holding platform to the beam-carrying vehicle. As a lifting device, complete the assembly and disassembly of the bridge machine. It is also used to erect bridges with low.

The arm is the main load bearing beam of the bridge frame and is a double box girder structure. According to the force conditions of the arm and finite element analysis, each box girder is designed as a box-shaped variable section.

Classification:

A bridge erector is very different from a crane in the normal sense of the word. Its requirements are demanding and there are girders walking on pieces, or called longitudinal movement. The bridge erector is divided into

1. highway bridge erector,

2. railway bridge erector,

3. public-railway bridge erector,

4. high-speed railway bridge erector,

5. section assembly bridge erector,

6. mobile moulding bridge erector.

The road and railway bridge erectors are generally single girder structures; the bridge builders are different from the bridge erectors in that the erectors are prefabricated girders placed on the piers, while the bridge builders have mould that can be poured directly on site.

Features:

As with other cranes used in general industrial buildings, there is adequate safety equipment, such as

1. Quality problems of products sold by our company will be solved as per the “three guarantees” system of our company by the “three guarantees” service team;

2. Related personnel will be sent to the site immediately after receiving quality complaints (by call, letter or oral notice) from clients;

3. Personnel involved in after-sales service shall be serious and considerate in handling the problem to make clients care-free;

4. In addition to solve quality problems, personnel involved in after-sales service shall train clients, answer their technical inquiries and related questions free of charge;

5. Related cost for products with quality problem will be shouldered by our company. Our company charges for quality problems caused by clients (or problems after the warranty term), but the charge will not be higher than the expense (or cost).

However, as the bridge erector is a large-scale special equipment for bridge installation, the safety factor at the construction site is required to be high. In addition to having professional personnel on site to direct the bridge erector, the speed requirement of the bridge erector is generally low and runs relatively slowly, which also ensures safety.
