Double girder gantry crane carrying capacity, span, good overall stability, variety, but the quality of their starting weight compared with the same single-girder gantry crane to be bigger, the cost is higher.electromagnet overhead crane Depending on the main beam structure, it can be divided into box beams and trusses in two forms. More commonly used box structure.
1, hook single girder gantry crane project is mainly applied to roads, bridges, power plants, factories and other construction, general handling and lifting handling operations.
2, the whole truss structure, light weight, wheel pressure is small, reliable performance.
3, the machine uses a single main beam, main beam on both sides of the car under the rope, lifting the shape of larger items.

Bridge crane

Bridge crane is Hengjia in workshops, warehouses and material lifting field empty for material lifting equipment. Because it is located on both ends of the tall concrete pillars or metal stents, shaped like a bridge.bridge gantry crane Overhead crane lay on both sides of the bridge along the elevated track longitudinal running, you can take full advantage of the space below the lifting bridge materials, unhindered ground equipment. It is the most widely used, the largest number of a crane.
Bridge crane is a new generation has the following advantages lifting equipment:
1, light weight, wheel pressure is small, small gauge size, reliable performance, easy to operate lifting equipment, a variety of material handling places preferred models.
2, the wheel pressure is small, bound small size, it can reduce pre-engineering investment in plant, etc., while lighting, heating and other facilities but also save some costs.
3, product performance and reliable, durable, the additional cost of products in the late stage of the process required to minimize: on the one hand due to the use of high-quality, high-performance parts makes maintenance and repair workload reduced; on the other hand the total installed capacity power (energy) decreased, but also to make use of cost savings.

double girder gantry Crane Category

Crane means within a certain range vertical lifting and carrying heavy loads of horizontal multi-action lifting machinery. Also known as cable car. At present, the major heavy lifting equipment Ltd. Guangdong Shun launch has gradually canceled hoist with function. The main features of terrains are: its driving cab and crane cab combined, is evolved by the crawler crane (crawler), will track and walking part of the running gear bracket into the chassis has a tire to overcome disadvantage of ship gantry crane crawler crane (crawler crane) track shoes on pavement damage, belonging to material handling machinery. Lifting equipment to do some work is characterized by intermittent exercise, namely a working cycle Reclaimer, transport, unloading and other movements of the respective agencies are working alternately, development and use of cranes on the market more widely. Because they are not leg slings and hoists with often some accident, driving speeds are more cranes (crawler) fast; job stability, lifting capacity, can hoist walking within a specific range, but must ensure that road smooth solid tire pressure to meet the requirements, hanging above the ground shall not exceed 50CM; ban with a load of walking long distances. To ensure the safety of operations, the current domestic basically prohibit the outriggers are not hoisting operations.

Bridge crane Overview

bridge gantry crane is Hengjia in workshops, warehouses and feed field empty for material lifting lifting equipment. Because of its ends situated on tall concrete pillars or metal stents, shaped like a bridge. overhead gantry cranes lay on both sides of the bridge along the elevated track longitudinal running, you can take full advantage of the space below the lifting bridge materials, unimpeded ground equipment. It is the most widely used, the largest number of a lifting machinery. 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, not hampered by ground equipment. This crane is widely used in indoor and outdoor warehouses, factories, docks and outdoor storage yard and other places.

Crane Maintenance

With the rapid development of China's urbanization, the crane with its strong scalability, large capacity characteristics, in terms of construction, cargo handling and other playing an increasingly large role. However, due to the risks involved in the field of mechanical and electrical construction cranes and aerial work operation, etc., it also became a construction safety Each crane driver must pay attention to the matter.
1. Do not pay attention to maintenance from the weight of limiter does not regulate the limiter from the weight on the use of, or even deliberately do not, or increase the limit value, so that from the weight of limiter should not restrict the protective effect.
2. The lifting mechanism brake not adjusted too loose. When overweight high speed decentralization, due to the inertia of the system could not produce coasting fall.
3. Wrap rate mechanism, when the 2-for-4 magnification switching magnification is not in place, did not pay attention to check, or no increase insurance sales, in lifting the pulley activity will suddenly drop, causing a major accident.
The twisted rope play rope serious disorder, not immediately removed, forced to use.

Jib crane classification

Jib crane series can be divided into:

1,slewing jib crane

2, JKBK slewing jib crane

3, mobile jib crane

4, wall mount jib crane

5, wall jib crane line

6, light gantry jib crane

7, crank jib crane

8, arms jib crane
