Compared with the general QD type double-girder bridge crane, LH type crane has the advantages that the self-weight is reduced by about 15-30%, and the wheel pressure is reduced by about 10-35%, which can reduce the crane's requirements for the plant structure and save plant manufacturing costs in the early stage of construction.
(1)The main beam adopts the off-track box structure, and the end beam is connected with high-strength bolts, which is convenient for transportation. Specialized processing equipment ensures the connection accuracy of the main and end beams and makes the crane runs smoothly.
(2)The hoisting trolley is an open and compact hoisting structure, and European-style hoist trolleys can also be used for medium tonnage according to customers' requirements.
(3)The running mechanisms of the trolley and crane adopt the European technology three-in-one drive form, and the hardened surface reducer has a compact structure with low noise, no oil leakage and long service life.
(4)Due to the use of European-style compact trolley and high-strength materials, the overall crane is small in size and light in weight. Compared with QD type traditional crane, the height of the plant can be reduced under the same lifting height, which effectively reduces the cost of the plant.
(5)Modular design, short design cycle, high degree of generalization, and improve the utilization rate of parts.
(6)Compact structure, low headroom, small size, large working range, effectively improve production efficiency.
(7)Full frequency conversion control, stable operation, no impact, slow speed for heavy load, fast speed for light load, energy saving and consumption reduction.
1). Reasonable structure,easy installation and maintenance;
2). Lightweight design,strong bearing capacity ;
3). Soft starting and stopping,Low noise;
4). Low control voltage, Safe and reliable operation ;
5). Low cost maintenance, longer service life;
6). Strong box type,made by one time forming machine.
