液压绞车

液压绞车是一种在船上使用的大型甲板机械。它用于拉或扔绳索。它通常安装在船的主甲板或船尾用于系泊绳索。

液压绞车主要由底座，支架，滚筒，制动器，松轮，齿轮箱，电子控制系统，液压动力组件等组成，其型号由船舶尺寸和系泊力决定。

当船停泊在海上或由银行停泊时，系泊绞车可以有效地运行。它具有许多功能，如在装卸过程中漂移，支撑和定位。其恒定张力调节偏差由补偿振动产生。当锚泊船舶装载和卸载时使用固定在岸上的系泊绞车这一事实是恒定张力调节的极好的应用实例。液压绞车通常是额定负荷大的液压绞车。以上10t至5000t负载的绞车设计为液压形式。

它主要由液压马达（低速或高速马达），液压常闭多板制动器，行星齿轮箱，离合器（可选），鼓，支撑轴，齿条，滚轮固定装置（可选）等组成。液压马达具有很高的机械效率和起动转矩。它可以根据工作条件的要求安装不同的分配器。其阀箱可定制并集成到电机的油分配器中，例如平衡阀，过载阀，高压梭阀，调速换向阀或具有其他性能的阀箱。制动器和行星齿轮箱等直接安装在鼓中。滚筒，支撑轴和齿条由动力要求设计，其结构坚固，结构简洁合理，具有足够的强度和刚性，系列的绞车的结构特点是结构紧凑，体积小，重量轻外形美观，性能优良，安全性好，效率高，起动转矩大，低速稳定性好，噪声小，运行可靠等特点。

The hydraulic winch
The hydraulic winch is a kind of large deck machinery used in the ship. It is used to pull up or throw ropes. It is usually mounted on the main deck of the stem or stern of the ship for mooring ropes.
The hydraulic winch mainly consists of base, support, drums, brakes, loose drums, gearboxes, electronic control systems, hydraulic power pack, etc. Its type is decided by the size of the ship and mooring force.
The mooring winch can run effectively when the ship is berthing in the sea or by the bank. It has many functions such as to drift, support and locate in the process of loading and unloading. Its constant tension adjust deviation generated by compensation vibration. The fact that the mooring winch fixed on the bank is used when the anchoring ships are loading and unloading is a excellent application example of constant tension adjustment. The hydraulic winch is usually the one with great rated load. The winch with above 10t to 5000t load is designed to hydraulic form.
It mainly consists of the hydraulic motor(low-speed or high-speed motor),hydraulic normally closed multiple plate brake, epicyclic gearboxes, clutches(optional),drums, support shaft, rack,  roll-fixed device(optional),etc. The hydraulic motor has great mechanical efficiency and starting torque. It can be fitted with the different distributors by the requirements of  working condition.  Its valve boxes can be customized and integrated into the oil distributor of the motor, such as balance valve, overload valve, high pressure shuttle valve, speed governing reversing valve, or valve boxes with other performances. The brakes and epicyclic gearboxes, etc are mounted directly in the drums. The drums, support shaft and the rack are designed by dynamics requirements, and its massive structure is concise and rational and has enough strength and rigidity, so the winches of series are characterized  by, structurally speaking, compactness, small in size, light in weight, nice appearance, and in terms of the performance, it is featured by good safety, high efficiency, great starting torque, good stability at low speed, small noise and reliable operation, etc.
