electric hoist manufacturers

over head cranes known as balancing crane, it is the use of four-bar linkage principle to make the load and the counterweight constitute a balanced system, you can use a variety of spreader flexible and easily lifting loads in three-dimensional space. Balanced crane lightweight and flexible, is an ideal lifting small items of lifting equipment, it has been widely used in factory floor machine loading and unloading, inter-process, automatic line, production line of the workpiece, lifting sand box, parts assembly, electric hoist manufacturers and railway stations, docks, warehouses and other occasions

double girder overhead travelling crane

double girder overhead travelling crane  use the occasion to span a larger building height larger workshop or warehouse, approached the wall near the lifting operations more frequently best. Multi-wall line and the top of the crane girder bridge crane or with the use of the service at close to the wall in a rectangular space, is responsible for lifting small light objects, metallurgical electric hoist large borne by the beam or bridge crane.

single girder bridge cranes

overhead cranes is widely used in indoor and outdoor warehouses, factories, docks and outdoor storage yard and other places. Bridge crane bridge crane can be divided into ordinary, simple girder bridge crane and metallurgical dedicated bridge crane three.General overhead cranes generally consists of lifting trolley, bridge run institutions, single girder bridge cranes bridge metal structures. Lifting trolley and consists of hoisting mechanism, trolley traveling mechanism and a small frame three parts.

electric wire rope hoist manufacturers

electric hoist manufacturers is a bridge crane runs on an elevated track, also known as the crane. Overhead crane lay on both sides of the bridge along the elevated track longitudinal run, lifting the car along the track laid on the bridge sideways, forming a rectangle the scope of work, you can take full advantage of the space below the lifting bridge materials, electric wire rope hoist manufacturers not hampered by ground equipment.

light duty electric winches

gantry crane manufacturer October 2011, China's construction machinery industry downturn in overall sales trends do not change. Among them, the excavator sales fell 29.92%; bulldozer sales fell 21.34%.
In 2011, influenced by the national macro-control, leading to some credit tightening in slowing the progress of construction projects, some of the projects planned to start the delayed start; at the same time consumers affected by the tightening of credit, purchase costs due to reduced demand for construction machinery reduced. Despite the current construction machinery market is facing serious challenges, but China's economic growth momentum is still strong in the coming period of China's construction machinery industry is still in rapid development, light duty electric winches especially crawler crane industry prospects.

metallurgical hoist crane

1, when the first class lifting weights (or the maximum load weight) should be suspended 0.5 m height from the ground after the weight is lowered again,
metallurgical hoist cranezcheck brake performance,wall traveling cranes reliable after confirmation, then normal operation.
2, strict implementation of Ten is not hanging system.
3, abnormal, immediately shut off the power, check the cause and immediately removed.
After work,
1, the hook is raised to a certain height, carts parked in the designated position, the control lever in the zero position, pull down the knife, eot crane cut off the power.
2, routine maintenance.
3, do shift work.

single girder overhead cranes

Lifting height refers to the top surface of the grab cranes orbit (or floor) to the vertical single girder overhead cranes distance between the extreme positions extract device, The magnitude of the rotational arm erecting crane means horizontal rotation centerline and extract means the distance between the vertical line, in units of the Working speed is the crane working body at rated load and stable operation speed.From the weight refers to lifting heavy objects mass,electric winches Can be divided into nominal weight, maximum weight, the total starting weight, effective from the weight and so on.

electric wire rope hoist manufacturer

First, electric wire rope hoist manufacturer if the line hanging problems, must after a power outage and power switches wears a sign the job before inspection or repair work to do. It also should be noted that the hook is in the lower limit position, roll on must retain more turns of safety ropes to do the above work, but we should also pay attention to: lifting heavy objects, when the liquid metal, explosive and dangerous goods must be slowly lifted from the ground , bridge crane the brake test reliability.

The crane driver device

electric magnetic overhead craneThe drive device is used to drive working organs of power equipment. Common drive electric drive, internal combustion engine drive and human power, etc. Electrical energy is clean and economic energy, electricity is the main drive of the modern crane type, almost all of the running over a limited range of rail crane,... elevator, the elevator is driven by electricity. For the flow of mobile crane at a distance (e.g., truck crane, cranes and crawler crane) more driven by internal combustion engine. 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

The prototype of the 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 mat...erials, and adopts hydraulic drive. During the late 19th century, steam-driven gradually replaced the hydraulic drive the crane crane. In the 1920 s, 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

wall traveling cranes

Polymer materials may prevent disassembly, repair and materials have excellent adhesion, oil resistance, wall traveling cranes and 350% of the tensile strength, good to overcome the impact of vibration reducer, repair effect is more effective than the traditional methods. Wear governance Bridge crane wheel and the cart speed reducer is running is frequent, multiple reversal stop and parking will cause the reducer shaft torque, vibration, overhead bridge craneseasy to cause leakage. After the occurrence of this kind of problem, 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;
