What are the advantages of a single beam crane?

Answer:

2) the car run the organization The operating mechanism of single beam crane electric hoist is electric car type. Reduction gear of 40 cr forging, and the conditioning treatment, installed in a closed reduction box, all adopt the rolling bearing, wall plate made of steel plate, guarantees flexible operation, easy to use, long service life. The car is equipped with inverter, the speed adjustment, smooth operation, accurate positioning and comfortable operation. 3) the big car run the organization The main engine of single beam crane is made of motor, reducer and wheel, and the wheel is 45 # forgings, and the hardness of heat treatment is greater than that of the tread HB, which is greater than 330%-390, and the depth of 20mm is greater than 260. The material of the shaft and gear is 45 or 40Cr. Cart driver for new type LDA drive device, the device has simple structure, small volume, large starting torque, but frequent starting, speed smooth, low noise, safe and reliable to use, easy installation and maintenance, beautiful and easy, etc. The big car of the single-beam crane is equipped with a frequency converter, no speed regulation, smooth operation, accurate positioning and comfortable operation.

All the plates are automatically made by nc cutting machine, and the preset beam arch is used to avoid the problem of the bending of the main beam. 5) steel shot blasting treatment, the surface roughness to GB8923 "steel surface treatment before painting registers and descaling grade of Sa2.5 level, improve paint adhesion, not to take off the lacquer, ensure single-girder crane machine long and beautiful The main girder girder seam welding with the advanced automatic plane in the country, the shape is beautiful, the welding quality is ensured. 7) large car beams are made of rectangular tubes, not spliced, welded, beautiful and durable. The wheel installation adopts the boring type installation, avoid the wheel tread not in the same horizontal plane, improve the operation precision of the wheel.

Characteristics of steel structure 1) the material of main steel structure (main beam and end girder) is adopted q235-b, and the materials used are materials report and corresponding certificate of qualification. The manufacturing, welding and testing of steel structures shall be carried out by national standards. The welding technology of double-sided groove welding is adopted in the welding seam of the main force, and the inspection and non-destructive inspection are carried out in accordance with the regulations, and all welders hold the corresponding certificate of grade. The main beam of crane adopts the whole slab without docking process, and the welding seam of the steel plate is cancelled, and the potential of the welding system is eliminated. (steel plate butt welding is the most important welding, which is the most dangerous area)

The composition of single beam crane The electric single-beam crane mainly consists of three main operating institutions: the lifting operation, the big car running body, the car running body. The main components of the hoist are electric gourds, wire ropes, pulleys, hooks or suspenders. Electric single-beam bridge crane metal structure is mainly composed of two parts of the main girder and end beam, its main girder structure for beams and steel plate combination section, made up of cover plate, web and flange beam, the casing and vertical and horizontal length of reinforced plate. Its safety and reliability directly affect the operation quality and working ability of crane
