subject: Hydraulic Winches Are Mainly Large Winch Load Rating [print this page] Winch in accordance with its use can be divided into: manual winch, electric winch, pneumatic winch, hydraulic winch of four.
In accordance with the reel drum and the form is divided into single and double drum.
In accordance with the distribution in the form of rolls into a tie for the double-double rolls and rolls.
The main technical indicators of hydraulic winch load rating to support the load, speed rope, rope capacity and so on.
Winch drum is rope, or chain winding or traction to enhance the small light weight lifting equipment, also known as winches. Winch can be used alone as a crane, road construction, and mine hoist and other machinery in the component parts, because of simple rope around a large, mobile home convenient and widely used. Also known as hoist winch. The product is versatile, compact structure, small size, light weight, major and easy to use transfer is widely used in construction, water conservancy, forestry, mines, docks and other materials drag down or flat, but also for modern electronic control Automatic operation line equipment.
Winch in accordance with the power divided into manual, electric, hydraulic three.
Manual winch handle rotation of the drive mechanism is equipped with a stop device, allows weight to keep the location in need. Assembly or upgrading heavy manual winch with safety handles and brakes should be set. Manual winch is generally used in weight from a small, poor condition of facilities or areas without power.
Electric winches are widely used in the heavy workload and the required traction for larger venues. Single drum electric winch drum drive motor through reducer, motor and reducer input shaft fitted between the brake. To meet the enhanced traction and rotation and other operations needs, as well as two-reel and multi-drum winch device. Generally lower than the rated load can be designed 10T winch electric winch.
Hydraulic winches are mainly large winch load rating, generally more than 10T to 5000T winch hydraulic winch designed. Winch by function can be divided into: Marine Winches: marine winch can be divided into drag winches, mooring winches, anchor winches, traction winches, etc..
Engineering Winch: mainly used in projects to enhance the functions and main hoist.
Mine Hoist: hoist into, scheduling winch, drilling winch, prop winch, rake mine winch, winch and other prop.
Cable winch: mainly used when laying cable winch.
A complete hydraulic system consists of five parts, namely, power components, the implementation of components, control components, auxiliary components and the hydraulic oil.
The role of dynamic components is the original motivation of the mechanical energy into fluid pressure energy, refers to the hydraulic system pump, which provides power to the entire hydraulic system. Structure of hydraulic pumps generally gear pumps, vane pumps and piston pumps.
Implementation of the components is to pressure the liquid can be converted to mechanical energy to drive the load in a straight line reciprocating motion or rotary motion.
Control elements in the hydraulic system to control and regulate fluid pressure, flow and direction. Under the control of different hydraulic pressure control valve can be divided into valves, flow control valves and directional control valves. Pressure control valve is divided into relief valve, reducing valves, sequence valves, pressure switch, etc.; flow control valves including throttle, adjusting the valve, diverting flow valve assembly; directional control valves, including one-way valve, check valve , shuttle valve, valve and so on. Under the control of different ways, Hydraulic control valve can be divided into switching valves, control valves and set the value of proportional control valves.
Auxiliary components including fuel tank, filter, tubing and pipe joints, seals, quick couplings, high pressure ball valve, hose assembly, pressure measurement joint, pressure gauge, oil level, oil temperature meter, etc..
Hydraulic oil is a hydraulic system transmits energy to the work of the media, there are all kinds of mineral oil, hydraulic oil emulsion Hop forming broad categories.
