我厂冶金半成品车间10t 18m 双悬臂龙门起重机是1978年自行设计制作,1979年竣工投产的。该设备是吊运钢锭的主要设备,过载能力强,自重和载重稳定性令人满意。尤其是运行机构选用3000型双列向心球面滚子轴承,至今运转正常,使用寿命和运行性能都大大优于7000型圆锥滚子轴承,很受用户欢迎。1 初选技术特性自制小型龙门起重机技术特性的初选需遵循以下3条原则:(1)根据用户要求,参照标准系列确定
I plant metallurgical semi-finished products workshop 10t 18m double cantilever gantry crane was designed and manufactured in 1978, completed and put into operation in 1979. The equipment is the main equipment lifting ingot, overload capacity, weight and load stability is satisfactory. In particular, the operating mechanism used 3000 double row radial spherical roller bearings, has been operating normally, the service life and operating performance are much better than 7000 tapered roller bearings, very popular with users. 1 primary technical characteristics Homemade small gantry crane technical characteristics of the primaries need to follow the following three principles: (1) According to user requirements, with reference to the standard series to determine
