The tenth section Electrical systemsElectrical systems including batteries, DC motor, three-phase AC generator, lighting and electrical instruments, monitoring and control instruments, safety components, sound and light alarminstallations. Electrical components adopt imported famous international brands. System voltage is24V, negative ground, lines introduce a single system. Instruments, instrument panels, lamps, andother configuration achieves the domestic advanced level.The eleventh section Festival safety protectionYZ12-vibration road roller has a comprehensive safety device z equipped with roll protectiondevice (ROPS).articulated fixed security bar: roller unloading ship or when long time reset fixed articulatedframe.tart locking device when long time reset fixed articulated frame. tart locking device: when the rollerof the joystick is in stall or high and low frequency select switch is not in the 0 position could notstart the engine.s equipped with emergency braking device.cover pieces opened automatically protection device: Dang cover pieces in manually hydraulic pumprole Xia up opened Shi, security protection device can prevent cover pieces accident whereabouts,dang maintenance end to lowered cover pieces Qian, will manually hydraulic pump above of softaxis manipulation device pull, cover pieces can in pump role Xia by oil cylinder will of pull Xia,cover pieces closed Hou will soft axis manipulation device promoting to. (Note: lowered panels mustbe pulling the flexible Manipulator. )The twelfthth section Transport and handling safety requirementsSafety requirements for transport and handling under normal circumstances, roller not longdistance at high speed. Long distance (30 km) when moving site, need towing equipment shipment.I. Transport whether it be road or railway transport, road roller selection must have the appropriatevolume of transport vehicles and loading capacity. Transport, frames before and after fixed withhinged safety Rod should be connected together, and also to take the necessary measures to preventthe rollers sliding and rolling.II. handling when loading and unloading roller, loading and unloading tools must have sufficientbearing capacity. When you use a cable car loading and unloading roller, using Center articulatedframe fixtures must first be fixed when using large flat hook lift, to ensure that the rollers remain flatstate after lifting.
1.行驶、振动和转向三大系统均为液压传动，且三个系统的液压泵连成一体，由发动 机曲轴输出端通过弹性联轴器直接驱动各泵，然后由各控制元件控制各系统的马达使各系统运转。
