Installing and setting up the boom crane slip ring slip ring should Hold the electrical slip ring, mounted on the spindle cantilever beam crane main beam of the upper part of the column through a side door aperture. There slip ring bore a keyway, using electrical slip ring keyway aligned to key pin rectangular beam on the spindle keyway installation, and then install the insulating gaskets and tighten the locking cap over the line. Finally, adjust the position of the brush holder, you know the appropriate date. Jib cranes Cranes for light intensity, cranes lifting equipment from the stem nine Shaanxi, swing arm and hoist rotary drive unit consisting of nine Shaanxi lifting equipment, the lower end of the column anchor bolts through the concrete foundation, the cycloid wheel deceleration devices to drive the boom swing, boom hoist on beam for about a straight line running and lifting heavy objects. Crane jib hollow steel structure, light weight, span, lifting capacity, economical and durable. Shaanxi nine built-in running gear lifting equipment, special engineering plastics go round with rolling bearings, friction is small, brisk walking; small structure size, especially help to improve the hook travel. When 0.5t-2t crane jib crane beam installation 0.5t-2t jib crane beam installation, rotary spindle aligning bearing hole at the top of the column; roller against the upright circular orbit slow down. Force through a side door pillar holes retaining washer and a round nut. Installation slip ring contacts mounting method has been talked about the last article, I am not doing explained. A crane boom crane observe the performance superiority of Chinese Academy of Sciences, issued today, China is one of the world's most intense natural resource waste country, ranked 56 in 60 countries inheritance observed. The internal combustion engine as dull dull engineering industry products in addition to the automotive industry the second largest use of industry because of its large emission intensity, emission targets and inferior to the car, so the pollution of the environment and more tense. Taizhou _ generous heavy lifting equipment (Online) _ nine lifting equipment provided by the generosity of heavy machinery in Henan Province. Heavy Machinery Co., Ltd., Henan Province, generous (www.hnqizhongshebei.com) (www.hnqizhongshebei.com) is Zhengzhou, engineering, construction cranes leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs. In heavy generous leadership with the staff warmly welcome all inquiries negotiations to create a better future for heavy generous.
