砼搅拌输送车从搅拌站接料后送往施工现场的过程中，在正常情况下车辆将重复实施接料→运送→卸料→接料流程。当输送车接料后万一发动机发生故障，致使分动箱输出轴无法驱动拌筒运转，俗称“死车”。若在砼初凝时段内无法恢复拌筒运转则拌简内的砼将会凝固，这样不仅损失6m3砼 After the mixing truck is sent from the mixing station to the construction site, the vehicle will repeat the process of picking, conveying, discharging, and picking. If the engine fails after the conveyer picks up the material, the output shaft of the transfer case cannot drive the mixer to run, commonly known as the “dead car.” If the operation of the mixing bowl cannot be resumed during the initial freezing period, the enthalpy in the mixture will solidify, which not only results in a loss of 6m3.
