GBM：THE LIFTING TROLLEY OF CRANE WITHOUT GEARBOX

GBM gearless lifting trolley is assembled by the GBM gearless driving unit independently developed by Jiangxi Gongbu Machinery Company and the world's original, combined with its light weight, low height, simple installation and other characteristics of the trolley frame design. Can be widely used in machinery manufacturing, logistics handling, ports, ships, papermaking, mining, nuclear power, construction, wind power, offshore heavy industry and other industries of lifting machinery equipment.</P><P> Compared with the traditional car and European car, GBM gearless lifting car has achieved six breakthroughs:</P><P> 1. The trolley frame structure has achieved a breakthrough: the three-beam custom structure is adopted, which is simple and light, and the wheel pressure distribution is even.</P><P> 2. The transmission mode has achieved a breakthrough. It abandons the traditional "motor + coupling - reducer + reel and other four-link transmission mode, and realizes the direct transmission, which is a subversive revolution in the development of crane industry technology</P><P> </P><P> 3, motor design technology achieved a breakthrough. By adopting various methods, such as optimizing magnetic circuit design and adopting new materials, it is the first in the world to overcome the problem of motor heating and realize ultra-low speed and large torque work.</P><P> 4. Brake safety protection has achieved a breakthrough. Standard disc type safety brake achieves zero speed braking and greatly prolongs brake life. It is equipped with special electromagnetic safety protection device. Even if the safety brake fails, it can protect the load from stalling slide.</P><P> 5. Achieved a breakthrough in the development of electronic control function. The key control technology of direct drive crane without reducer has been broken through, and a series of crane control functions with world leading level have been developed, such as fast light load, low speed operation, fixed distance point motion reservation function upgrade interface, etc</P><P> 6, clean and environmental protection to achieve a breakthrough: ultra-quiet, work noise less than 55 decibels; Clean environmental protection, can do any part of the oil, not oil leakage, ending the crane noise high, oil pollution history.
