5 tons of traffic, span 18 meters of housing, the need for large I-beam to do the bottom of the load beam?
The I-beam type is required to be 32-45C.The bearing beam is a traction machine, and it is a main component of the elevator, and the bearing beam of the tractor is an important component to support the main component. Because of the structural features of the elevator, the load bearing beam not only supports the tractor, but also the whole elevator. Including the car, load, weight, cable, wire rope, and so on, through the tractor and hanging on the load beam, it can be described as "one thousand Jun in a beam."".
Driving is a common installation of indoor and outdoor cranes. The traffic driving mode there are two basic types: one is concentrated drive which is a motor driving long drive shaft to drive the active wheel on both sides; the drive, which is active on both sides of the wheels driven by a motor. Medium and small bridge crane is increasinglyused brakes, reducer and motor are combined into one of the "three in one" drive, big weight of ordinary bridge crane for ease of installation and adjustment, adopt universal shaft driving device.
When the top of a building is not too high and there is enough room height, to avoid other equipment and room bearing beam in conflict with each other in the installation layout, the room construction load-bearing beam constructed two high concrete floor Taiwan 600mm, then the bearing beam in concrete platform, using this method, the general the bearing beam welding on the plate and the guide wheel drill hole, the guide wheel is fixed on the bearing beam.
The bearing beam is subjected to the elevator car, the weight bearing steel and other equipment, it took the full lift of the static load and dynamic load, fixed in the elevator shaft at the top of the room construction bearing beam, the materials used are steel or steel. The bearing on the elevator configuration mode of transmission beam is arranged in the room. The traction machine gearbox, adopts three bearing steel beam support, because the position of different steel structures are also different. When the building top floor with enough space height, according to the installation plan will be placed in the floor below the bearing beam, and the floor together. When the top of a building is not too high, according to the plan of the elevator bearing beam placed above and bearing room construction, floor spacing is greater than or equal to 50mm and the installation hole is reserved in the installation of the guide wheel place to leave the cross.
