Clean room crane configuration and technical specifications A, crane parts 1, the lifting mechanism Adopt chain hoist, hoist chain is not easy to damage, and friction produced less dust. 1) lifting chain: using Japan imported FEC80 super heat treated alloy steel chain, wear small, high service life and surface mounted to the chain, to prevent the chain and gourd on sundry fall; (2) chain bag: adopt stainless steel chain bag, wear small, without peeling paint and surface; (3) hoisting double speed, using slow when need accurate positioning, using fast when loading and unloading, effectively improve the use efficiency, (4) hook is made of stainless steel hook, reduces unnecessary wear and tear. 2, Drive institutions (1) the wheel adopts nylon wheel, effectively reduce the dust caused by the friction; (2) drive motor adopt the world's best the SEW motor, low noise, high efficiency; (3) drive adopts frequency conversion control, start braking stability, energy saving effect is obvious, and save the energy consumption of the expensive department. The second part, the structure of the crane With double beam type, the car was walking beam at the top, because of the friction generated clutter and workshop dust debris accumulation in the upper portion of the beam, easy to clean. (1) main girder material 304 stainless steel material, high strength, and the entire stainless steel plate production, the middle without welding seam; (2) main girder surface polishing by professional processing, the overall effect is bright and clean, and there is no paint falls off, and so on and so forth; (3) the car track stainless steel rail, reduce wear small wheels; (4) girder top mounted conductive groove of the lacquer that bake, prevent sundry, regular cleaning. Three, crane electrical parts (1) the hoist distribution using industrial chain system, wear small, easy to use, easy to maintenance; (2) the crane distribution using safety electric rail dust pan, electric rail without seam, to prevent falling debris, regular cleaning; (3) crane electrical schneider products in Germany, safe and reliable, low failure rate; (4) crane has overload protection, loss of pressure protection and direction limit protection.
