Thanks to the design features, two-frame bridge cranes have the mass of advantages. So, use of two beams instead of one, considerably increases rigidity of a design, allows to work at the same time at once with several lifting mechanisms working both separately, and together. Sale of two-frame bridge cranes is carried out by our company for the most reasonable prices.
Bridge two-frame cranes differ in a favorable side in existence of a box-shaped design and optimum calculated geometry of the screen allowing to receive exclusively high road performance and minimizing wear of a design during operation. Control of the two-frame bridge crane can be exercised as by means of portable or remote, including radio-controlled, the control panel, and directly from the operator's cabin. Undoubted advantage of this type of a design is the possibility of the highest raising of a hook as the last moves between crane beams. Thus, two-frame suspended cranes are deprived of shortcomings of one-frame cranes of similar type.
Two-frame bridge cranes of general purpose are the most widespread. And, both basic, and suspended bridge cranes enter this category. As a rule, they are equipped with the load gripping mechanisms having one more rare two hooks which if necessary can be transformed to magnetic capture. During the work with bulks, instead of hook capture the clamshell, allowing to provide wide range of transshipment works is established.
When working, various lengthy freights connected with transportation, special two-frame electric bridge cranes usually are used. Structurally, their difference from the ordinary two-frame crane consists available lengthy traverses, having two or more hooks allowing to distribute more evenly loading due to distribution of the last on all plane of the transported freight.
When working in the rooms having high degrees of danger, bridge two-frame cranes are equipped with three-stage system of the isolation allowing to exclude short circuit in power part of the crane. In addition, for safety increase, the two-frame cranes mounted on dangerous production, are equipped with the systems executed in fireproof and explosion-proof execution.
It should be noted undoubted pluses of two-frame bridge cranes:
- the increased design durability;
- smooth start-up and braking allow to move freights practically without rocking;
- insignificant increase in lump due to application of an additional beam allows to install two-frame bridge cranes on the designs having restrictions on tension;
- the available systems of protection against collision allow to operate several cranes on one subcrane way.
