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.

Crane inspection items

electromagnetic overhead craneOverhead crane safety inspection in order to ensure safe operation of the overhead crane, crane operation required during some routine security check on the project and highlights are as follows:
(1) lifting height limiter, travel limit switch and all the positive properties of interlocking institutions
(2) comply with the safety requirements of the major components: the opening is increased less than 15% of the original size, the torsional deformation of less than 10%; hook bushing wear plate is less than 50% of the original size, the mandrel plate hook wear less than 5%, no peeling burr, welding. Hanger hook and pulley no obvious defects. The surface of the wire rope wear, corrosion is less than 40% of the diameter of the wire, broken wires in one lay length within less than 10% of the total number of wires, no breaks, no thinning, no core prolapse, dead twisting, compressional deformation annealing, burning phenomenon.electric hoist manufacturers

End connections and fixed rope clips, clips, wedge block connection intact, no loose plate at least two, the number of no less than three catches. Roll no cracks, connections, fixed no loose; cylinder wall wear less than 20% of the original wall thickness; secure volume of not less than two laps, reel and rope diameter ratio of compliance. Balance wheel fixed intact, shall comply with the requirements of the rope. Brakes no cracks, no loose, no serious wear, brake clearance on both sides equal right size, there is sufficient braking force, brake wear with less than 50% of the original thickness.
By conventional overhead crane safety inspection, to prevent accidents, reduce equipment accidents, improve equipment operation rate and reduce maintenance costs etc play a significant role.

Crane origin

explosion proof electric hoist Cranes are commonly known as crane, crane (Crane) is a kind of lifting machinery, is a for loop, intermittent motion machine. A work cycle comprising: extract means to extract from the articles lifted, and then moved horizontally to the appointed place down the article, followed by reverse movement, so that the extract means to return the home position for the next cycle. Such as fixed-slewing cranes, tower cranes, truck cranes, tires, crawler cranes.
Within a certain range of vertical lifting and carrying heavy loads of multi-level action lifting machinery. Also known as the crane. Are material handling machinery. Crane's work is characterized by intermittent exercise to do that in a work cycle reclaimer, transport, unloading and other movements of the appropriate agency is working alternately. Crane

The 14th century, Western Europe and the emergence of the human animal driven rotating jib cranes.

The early 19th century, there has been a bridge crane; Crane important wear parts such as shafts, gears and spreader began to use metal materials, and began to use hydraulic drives.
Late 19th century, steam-driven crane gradually replaced the water-driven crane.
Beginning in the 1920s, due to the rapid development of the electrical industry and internal combustion industry to motor or internal combustion engine for a variety of crane power plant is basically formed. Crane
