foundry crane

,Electric double girder gantry ‪‎crane‬ gantry #crane is known or double girder gantry #crane. Mainly used for outdoor yard, 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,foundry cranein the swivel hoist circumstances, should pay close attention to whether there are obstacles around, if it should try to avoid or remove obstructions.

portal crane

Single girder gantry ‪crane‬ doors leg has L and C forms. L type of manufacture and installation convenience, the force was better, the smaller their own quality, but, lifting goods through space at the relatively small number of legs,Double girder gantry portal crane carrying capacity, span, the 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. Depending on the main beam structure, it can be divided into box beams and trusses in two forms

bridge cranes

Electrical‬ ‪ ‎hoists‬ By the motor, transmission and rolls or sprockets, divided into wire rope electric hoist and electric chain hoist two，Belong to special lifting equipment, has a compact, light weight, small size, parts versatility, easy operation，Motors generally used are conical motor stops automatically locked after brake，bridge cranes can be installed separately on the beam, it can also be installed using an electric or manual single-beam, dual-beam, cantilever, gantry cranes

Crane

grab crane is in a certain range of vertical lifting and carrying heavy loads of multi-level action lifting machinery. Also known as crane. At present, the major heavy lifting Equipment Co., Ltd. Guangdong Shun launch has gradually canceled hoist with function. The main features of the tire cranes are: its driving cab and crane cab combined, is evolved by the crawler crane (crawler) will be tracked and walking stents have become part of the running gear tire chassis, overcome the disadvantage of crawler crane (crawler crane) track shoes on pavement damage, belonging to material handling machinery. Lifting equipment to do some work is characterized by intermittent movement, that in a work cycle Reclaimer, transport, unloading and other movements of the respective agencies are working alternately,foundry crane development and use of more and more widespread in the market

girder gantry crane

1. The single girder
Single girder gantry crane structure is simple, easy to manufacture and installation, small own mass, main beam mostly Partial rail box-shaped frame structure. Compared with double girder gantry crane,electric magnetic overhead crane the overall stiffness weaker. Thus, when the starting weight Q≤50t, time span S≤35m, can this form. Single girder gantry crane gate leg has L and C forms. L type of manufacture and installation convenience, the force was better, the smaller their own quality, but, lifting goods through space at the relatively small number of legs. C-shaped leg made inclined or curved shape, aimed at a greater horizontal space to make the goods pass foot.
2. The double main beam
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. Depending on the main beam structure, it can be divided into box beams and trusses in two forms. More commonly used box structure. [1]
Crane, mainly by the bridge, traveling mechanism, trolley, electrical equipment and other components. Depending on the frequency of use, it is divided into A5, A6 two operating levels.
main feature:
(1) bridge with box girder, automatic submerged arc welding.
(2) the use of the trolley beam track conductive cable conducting new device, safe and reliable.
(3) The lifting mechanism may also be provided in accordance with the requirements of the second set of security devices. Increase reliability.
(4) parts standardization, serialization, universal.
(5) control room unobscured, all institutions are in the control room to manipulate, manipulate flexible working comfort.

Crane deeds

Since there is a truncated cone-liter overhead-column, after forward or backward truncated cone column, Renzi Jia style and bracing frame. Those who are required to set up the rotary tower crane counterweight, its function is to support the counterweight to constitute a role opposite direction and lifting torque design balance required torque. In addition to the counterweight, but also often installed in its tail lifting mechanism. The reason why lifting mechanism with a counterweight mounted trailing arms together in the balance, you can assign a weight to play the role of the Ministry and, secondly, increasing the distance between the rope reel and the spire of the guide wheel between rows to facilitate rope around and avoid arbitrary justice phenomenon. Counterweight inversely related to the amount and length of the balance arm, and then there is a certain proportion between the balance arm length and boom length.

Improve portal crane

Therefore, only to completely change the way the former governor to solve the problem of high failure rate overhead crane fundamentally. With the fast development of electronic technology, inverter performance and reliability have been greatly improved, for applications in bridge portal crane suppliers crane drive system provides favorable conditions. We first take on the important work of assembling diesel locomotive repair library shelf 32 t overhead crane hook size vehicle drive system and improve the system frequency transformation, to improve its operating performance and reduce the failure rate.
