lx type bridge crane

Lx type bridge crane"s power supply of this crane adopts AC 380V 50Hz, and the large car is powered by the safe sliding contact line; the electric hoist is used.

Cable power supply. The crane also has safety protection devices such as overloading protection and the limit of various mechanisms.

2. The main metal structure

The metal structure consists of a single main beam, a beam and other components.

Two point one

The U shape steel I-beam girder and welding box girder steel rolling forming the solid abdomen, abdominal beam is made of channel group, single main beam with the hinge, allowing a small swing angle (PIN) is connected to the wheel crane can better contact with the track, not vacant, because this detachable connection, convenient transportation.

The 2.2 beam is mainly welded by the welding of the type steel.

The vertical deflection of the wheel, the horizontal skew and the installation of the running mechanism of the big car are all ensured by the manufacture and welding of the beam. The main beam and beam are generally required to be installed and marked in the manufacturing plant to facilitate the smooth assembly of the site and to ensure the correctness and integrity of the metal structure assembly.

2.3 the panel and diaphragm material of the main beam and beam are Q235B, and the internal steel stiffener is Q235A, and the welding rod is used.

E4303 (GB5117), automatic welding wire using E501T-1.

Two point four

The metal structure of a crane has sufficient stiffness and strength, and its full load static deflection is not more than 1/700S.

3. Main institutions and facilities

Three point one

The hoisting mechanism of hoist type LX hoist lifting mechanism consists of conical rotor motor, reducer, reel device, coupling, guide rope, hook device, electric car, driving device and electrical appliances.

The components in the structure can be relatively independent, and the maintenance and adjustment is convenient.
