LX single-girder overhead crane hoisted single beam bridge crane works: single girder overhead crane hoisting mechanism comprises a brake motor, reducer, drum and pulley. Motor through reducer, drive drum rotation, so the rope around the drum or the roll down, to lift weights, small holder and mounting frame is lifting mechanism and trolley traveling agencies and other parts of the frame, usually welded structure. Single girder suspension crane operation mechanism driving mode is divided into two categories: one for the central drive, which uses an electric motor to drive the long drive shaft on both sides of Active Wheel; the other for each drive that active on both sides of each wheel with a motor drive, the more frequent use of a combination of a small bridge crane brakes, gearbox and electric motor as one of the "triple play" drive mode, from the weight of too general a large overhead crane for ease of installation and adjustment, often drives using universal coupling. Products crane hoisted single beam single-beam suspension crane installation crane is hanging on either side of a fixed beam above, so named suspension cranes. Crane hoisted single beam column because no other infrastructure, so there is a lot of space utilization allows for space above the narrow fixed plant. Single-girder overhead traveling crane with single-speed electric hoist CD1, MD1 model electric hoist supporting the use of two-speed, into a light rail running small crane. Suspension cranes used in factories, warehouses building of rail to the roof truss bottom chord height ≤500mm place. Single girder suspension crane to ground operations. Operating ambient temperature 25 ℃ ~ 40 ℃, prohibited in flammable, explosive and corrosive media environments. Starting weight: 1 ~ 10t; span: 3.5 ~ 22.5m; lifting height: 3 ~ 30m single-girder overhead crane to crane general purpose, used for low-rise buildings and warehouses, are the last two decades domestic single girder suspension crane leading products. Single girder suspension crane working environment temperature -25 ℃ ~ 40 ℃, relative humidity less than 85%, flammable, explosive and corrosive gases filled work environment does not apply. Single girder suspension crane drawings: parameters as follows: S-- span a total length of main beam I-- L-- cantilever L1-- left limit right limit h-- L2-- tread to hook the heart from the crane hoisted single beam structural features : single girder suspension crane bridge from the main beam, side beams and run bodies, single girder suspension crane girders directly using beam; beam + channel combination shelf; beam + plate-shaped grooves pressed into ∩ steel welded into a box-beam three forms. End of the beam by the channel, with the simple structure, easy manufacturing, end beam and the main beam using pin coupling (small tonnage, small span) or stationary welding (large tonnage, large-span) as a whole, as a load-bearing body. Single girder suspension crane operating agencies active wheels and passive wheels ran round the wall and composed by the double-headed screw placed on the end of the beam, hanging on the lower flange steel beams from the motor by deceleration mechanism is rotated, so as to achieve the purpose of running back and forth. Single girder suspension crane supporting CD1-type electric hoist is our own design, MD1 type electric hoist, electric hoist is a compact, heavy lifting to complete the lift can be run back and forth along the longitudinal beam lifting machinery . Single girder suspension crane electrical control mainly through DK2 type cabinet complete, easy to operate, single girder overhead crane also features ceiling-bit devices and carts from the end of travel limit switches protection, single-girder overhead crane carts conductive line current use DHG Safety trolley line to ensure safe and reliable operation of the crane. Single girder suspension crane structure: single-girder overhead crane consists of main beam, side beam, electric hoist and electric control of four parts. Single girder suspension crane main beam (bridge) two forms, small tonnage, small span of the beam (beam + channel), with and without the use of a structure in the form of beams; large tonnage, large span of products, the use Tire pressure plate forming a U-shaped channel and beam welded into a box set solid web beams, channel beams is composed of a main crane hoisted single beam, beam with a small angle to allow swinging single hinge (pin axis) connected to each of the wheels to make the crane better contact with the track, without floating. Also connected to removable, easy to transport. Single girder suspension crane girder metal structure (bridge processing) 1, first plate surface rust treatment by shot blasting machine, an increase adhesion of paint. 2, web and camber on the cover welding, according to crane span conditions first with the corresponding conic curve and two four four superimposed curves calculated by the computer to select point arch high production model, to stake out the web cutting. 3, the main beam welding are welding tooling and reasonable welding, soldering symmetry by two or four people, rational use of the current size and welding speed, welding deformation reducing crane 4, the main beam, side beam webs and upper and lower cover of butt welds, longitudinal welds in all submerged arc welding, all 100% inspection after welding. 5, the docking bridge docking and door beams, side beams take lofting platform, positioning, lifting flip, to ensure that the geometry, to control welding distortion.
