XHSJ20 tons

product description:

XHSJ seriesThe hydraulic winch is composed of various flow distributors with one-way balance valve and high-pressure shuttle valve to control the brake, XH series hydraulic motor, Z-type brake, C-type gear reducer, reel, frame and other components (the hydraulic principle is shown in the figure ), the user only needs to be equipped with a pump station and a reversing valve. Since the winch has its own valve group, it not only simplifies the hydraulic system but also improves the reliability of the transmission. The hydraulic valve group that comes with the XHSJ winch successfully solves the problems of empty hook vibration and secondary sliding during lifting in general winches, making the XHSJ hydraulic winch run smoothly during lifting and lowering. In addition, it also has the characteristics of high efficiency when starting and working, low energy consumption, low noise, beautiful appearance, compact size, and good economy. It can be applied to gravity crushing traction equipment, crawler and marine cranes, truck cranes, In equipment such as pipelayers, grab buckets and drilling rigs with crushing functions.

Product model example:

XHSJ6-120-315-30-ZPH said:

The modulus of the planetary reducer is 6, the tension of the first layer of the wire rope is 120KN, the rope capacity of the drum is 315m, the diameter of the wire rope is 30, a hydraulic winch with a brake and a one-way balance valve, and a pressure rating of 20MPa.

Product model description:

Product parameter description :

1. The total displacement of this series of winches is the amount of oil supplied per revolution of the drum.

2. The oil supply volume is the theoretical flow rate of the pump station, that is, the calculated value obtained by considering the system efficiency of 90%.

3. The rope capacity is the theoretical maximum rope capacity of the winch . The actual allowable effective rope capacity should consider keeping 3 turns of the wire rope for use to prevent the rope end from falling out.

为了避免螺旋锥齿轮减速机做为泵运行的制动系统马达产生气蚀或缺失制动系统工作能力，应确保这时马达的去油边有充足的补油工作压力。

①它能通过闭试回路里的补汽油泵或开启式回路里的背压阀来完成；

②当液压马达推动大惯性力负荷时，应在液压传动系统中安装与马达并接的旁通阀节流阀补油，以防关机情况下惯性力健身运动的马达油少。

对于不能承受额外轴向和径向力的液压马达，或者液压电机可以承受额外的轴向和径向力，但特定的工程机械液压马达轴向和径向力超过液压电机允许的轴向力或径向力，应考虑连接电机输出轴和工作机构。必须低速档运行的马达，要核查其最少平稳转速。
