After the occurrence of this kind of problem, electromagnet overhead crane traditional methods is given priority to with machining after repair welding or brush plating to repair, but both have some disadvantages: repair welding high temperature thermal stress can not completely eliminate, prone to bend or break; And brush plating coating thickness restrictions,foundry crane easy to peel, and two methods above are with metal repair of metal

single girder overhead crane

single girder overhead crane Leakage repair protect Bridge crane trolley reducer due to vibration, wear and tear, pressure, temperature and other factors, the joint surface static seal parts often appear leak phenomenon. Traditional treatment method to remove the speed reducer, replacement or daub sealing gasket sealing glue, but time-consuming, la...borious and difficult to ensure the sealing effect, will once again appear leakage in the run. double girder bridge crane The contemporary western countries with high polymer composite material field leakage of governance

single girder bridge cranes

During the late 19th century, steam-driven gradually replaced the hydraulic drive the crane crane. In the 1920 s, single girder bridge cranes due to the electrical industry and the rapid development of internal combustion engine industry, driven by motor or internal combustion engine device basic form of all kinds of crane. crane shipbuilding gantry crane

container gantry crane

portal crane manufacturerChina's ancient irrigation farmland with orange is the prototype of the crane boom type. In the 14th century, Western Europe in the human and animal driven rotating arm type crane. Appeared at the beginning of the 19th century, the bridge crane; Crane important wear parts such as axle, gear and sling started using metal erials, container gantry craneand adopts hydraulic drive

shipbuilding gantry crane

Human power is suitable for some small light lifting equipment, but also used as some auxiliary equipment, spare drive and accidental temporary power (or accident status) electromagnetic overhead crane，driven by motor or internal combustion engine device basic form of all kinds of crane. crane shipbuilding gantry crane

unhindered ground equipment.

Advantages truck crane is good mobility shift rapidly. The disadvantage is that the legs have to work and can not load driving, cranes spare parts not suitable for work on soft or muddy field. Truck crane chassis performance is equivalent to the total weight of the vehicle the same truck, meet the technical requirements of road vehicles, which can be used freely on all types of roads,Bridge crane is Hengjia in workshops, warehouses and empty field for material lifting material lifting equipment.Bridge crane lay on both sides of the bridge along the elevated track longitudinally running, single girder crane you can take full advantage of the space below the bridge lifting materials, unhindered ground equipment.
