D-type single-girder overhead crane 5 t single-girder bridge crane features: 5 t single-girder bridge crane is generally equipped with a traveling mechanism by a bridge, and containing from electric hoist, electrical equipment, cab lifting mechanism, etc. Several major components. 5 t single-girder overhead crane looks like two ends supported on two parallel translation overhead track running flat single span bridge. 5 t single-girder bridge crane hoisting mechanism for vertically items, hoist trolley is used with a load lateral movement; bridge and traveling mechanism used to lift cars and articles for longitudinal movement, in order to achieve within the span and composition within the specified height three-dimensional space with moving and handling objects. 5 t single-girder bridge crane Product description: 5 t single-girder bridge crane with a reasonable structure, machine rigidity characteristics. 5 t single-girder overhead crane with single-speed electric hoist CD1, MD1 model electric hoist supporting the use of two-speed, single-girder bridge crane 5 tons is a small light lifting machinery. 5 t single-beam bridge crane are intermediate work system, which from the weight of 1t-20t. Span 7.5-31.5m. Work levels for A3-A4, the working environment temperature -25 ℃ ~ 40 ℃. Single girder crane lifting goods are widely used in various occasions workshops, factories, warehouses, material, etc., is prohibited in flammable, explosive, corrosive the use of the media environment. 5 t single-girder bridge crane cab has two operating surface and forms to meet customer needs in the case of a variety to choose. 5 tons of single girder overhead structure: 5 tons single girder overhead bridge crane is generally run by the agency, electric hoist, bridge metal structures and electrical components. As five tons electric hoist single girder overhead crane hoisting mechanism, and run along the main beam. 5 tons of metal structures single-girder overhead traveling crane from the main beam and side beams composed of five tons of single girder overhead crane main girder bridge by a single span girders and located on either side of the end beam composition, the main beam and side beams rigidly connected, both ends of the end of the beam is equipped with wheels for supporting the run on an elevated bridge. 5 t single-girder bridge crane main beam welded beam for hoist operation. The main beam of the bridge structure type more typical box-shaped structure, four truss structure and fasting truss structure. L single-girder gantry crane works: L-type single-beam gantry crane by driving means, work organization, extract device, operation control system and metal structure. By manipulating the control system, L-type single-beam gantry crane drive unit will power energy input into mechanical energy (ie appropriate force or velocity), before being passed to extract devices. L single-girder gantry crane extract device will be the movement of materials in touch with the crane up, through the work of bodies alone or in combination movement, complete material handling tasks. Movable metal structure will connect the components into a whole, and carrying the weight of heavy cranes and hoists. L single-girder gantry crane Product Description: L-type single-beam gantry crane is suitable for open-air yard, warehouses or railway for general handling and lifting handling operations. L single-girder gantry crane from the bridge, traveling mechanism, trolley, electric equipment and other components. Bridge with box-type single-beam welded structure, traveling mechanism adopted separately driven. All agencies are in the control room or remote control operation. Crane conductive form two types of cables and trolley line, choose one when ordering. L single-girder gantry crane features: Shed L single-girder gantry cranes are mainly used for outdoor, yard goods, bulk cargo loading and unloading operations. Its metal structure shaped like a door frame, carrying the main beam install two feet down, you can walk directly to the track on the ground, both ends of the main beam may have overhanging cantilever. L single-girder gantry crane with a space utilization, large operating range, wide adaptation, versatility, etc., are widely used in the yard. L single-girder gantry crane drive with triple system, electric speed control using non-contact module, and can be achieved with very little speed and two-speed close to the inverter, the operation is lifting electric realizable particularly smooth, with overload alarm, hanging crooked oblique pull, anti-hook hoisting secondary protection, missing items overcurrent protection, stage (handle) using 36V safe voltage in order to achieve a multi-functional protection. Main voltage 380V + from 5 to 10% when long-term use of electronically controlled "2 million" times. L single-girder gantry crane process: First, the crane 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. Second, the car is working trolley crane lifting mechanism goods, mainly by small frame, run institutions and winches composed enough. Small frame processing is the key to the car production, its quality directly affects car performance and hoist installation precision enough, which my company car end of the beam and the main beam connecting surface milling machine using a combination of car horn bearing housing adjustment board planing adjustments, each bearing surface with milling, car team, welded to the platform, the use of fixture, to ensure geometry, to control welding distortion. Third, processing traveling mechanism machining traveling mechanism, the key parts of this section is to gear coupling, gear coupling process we use within Y3150E, Y3180H and Y54L Precision hobbing and slotting precision machining, outer teeth, tooth surface with induction hardened, check the use of 3101,3603 comprehensive testing gear measuring instrument, precision can reach more than six. Alloy sports wheels are 50SiMn, we take a special heat treatment equipment, effectively ensure the wheel tread depth requirements for hardness and hardened layer ground
