XHJ5 ton internal expansion and external holding winch

product description:

The hydraulic winch is composed of hydraulic valve group, hydraulic motor, reduction box, reel, frame, internal expansion clutch, external holding brake and other components; when the winch is hoisting, the internal expansion is tightly held, and the external hold is filled with oil to release . When lowering, the oil is released from the inside and the oil is released from the outside, so it has the function of free release of the empty hook. When it is released freely, the pressure of the brake cylinder of the outer brake can be adjusted to control the release speed of the empty hook, which greatly improves the efficiency and reduces energy consumption. consumption; when the work is stopped, the external brake can be used as a brake, which protects the gearbox and other components well. The winch has holding points that are simple in structure and durable in use. Widely used in dynamic compactors, pile drivers, crawler cranes and various marine equipment. The inner expansion part of the XHLSJ winch is generally designed as a normally closed form, and can also be designed as a normally open form according to customer requirements.

Product model example:

XHLSJ60-150-22-ZP:

The tension of the first layer of the steel wire rope is 60KN, the rope capacity of the drum is 150m, the diameter of the steel wire rope is 20, with brake and one-way balance valve.

1、液压马达一般可以在短时间内超出额定压力20%-30%的工作压力下工作中，但一瞬间的较工作压力不可以和较大转速与此同时发生。

2、液压马达的回油道背压有一定限定，在背压比较大时，务必设定泄露输油管。

3、一般不可使液压马达的较高转距和较大转速与此同时发生。

①具体转速不可小于马达至少转速，以防发生爬取。

②当系统要求的转速低，而马达在转速、转距等技术参数不容易达到工作标准时，可在马达以及推动的服务器间加设降速组织。

③为了能在极低转速下稳定运作，马达的渗漏务必稳定，要有一定的泵油背压和至少35℃的液压油粘度。
