Z4-2型装载机,是成都铁路局白家装卸机械厂在1976年设计制造的,是一种单斗、前卸、液压操纵、轮式装卸机械。适用于筑路、城市建设、中小型的土木和水利工程,以及料场、港口、车站、电站等企业,用以装卸或转运枕木、砂石、卵石、煤炭、炉渣等松散物料。其特点为: 1.液力传动在发动机与变速箱之间装有液力变矩器,能使发动机的功率得到最大利用,可以增大发动机的输出扭矩,在一定范围内能适应外界阻力的变化,自行调节所需要的扭矩;在外界阻力突然增大时,可使发动机不致熄火,其他机件不致损坏,还可以进行无级变
Z4-2 loader, designed and manufactured by Baiji Loading and unloading Machinery Factory of Chengdu Railway Bureau in 1976, is a kind of single bucket, front unloading, hydraulic control and wheeled loading and unloading machine. Suitable for roads, urban construction, small and medium sized civil engineering and water conservancy projects, as well as yard, port, station, power station and other enterprises, for loading and unloading or transporting sleepers, gravel, pebbles, coal, slag and other loose materials. Its features are: 1. Hydraulic transmission equipped with a torque converter between the engine and transmission can make maximum use of engine power, can increase the engine output torque, within a certain range to adapt to external resistance Change, adjust the required torque; in the external resistance suddenly increased, the engine will not stall, other parts will not be damaged, but also can be carried out without change
