In a hydraulic system force that is applied at one point is transmitted to another point using a pressurized hydraulic fluid.

Hydraulic Winches

They are used to pressurized the hydraulic fluid and force the fluid through the system. There are three types of hydraulic pump:.

Fixed Displacement Pump — These pump has a set flow rate means every stroke of the motor moves same amount of fluid. Fixed displacement pumps are perfect for single jobs that to be repeated indefinitely over long periods of time.

Variable Displacement Pump — In Variable displacement pumps flow rate and outlet pressure can be changed as the pump operates. They are used to power a wider variety of tool, but require more expense and more attention. Hydraulic cylinder is a mechanical hydraulic actuator that converts hydraulic energy or hydraulic pressure into linear displacement.

It consists of cylindrical barrel, piston and piston rod. Pressure control valves limit the system pressure to protect the system components. There are four types of pressure control valve:. They are normally closed and it opens when the pressure exceeds a specified maximum value and diverts the pump flow back to reservoir or tank internally. They are located near hydraulic pump. They are normally open and closed if the pressure exceed beyond specified design pressure at outlet.

They are located near hydraulic actuator. They are designed to create backpressure at the return line of the actuator to prevent losing control over the load. A flow control valve is used for adjusting the flow rate of a fluid in a pipeline. The valve contains a flow passage or a port whose area can be varied. They are used in a hydraulic system that need to vary either flow or pressure to reduce lunge and shock. They controls the returning flow in relation to the flow being directed into opposite side of the actuator.

It is used in hydraulic system to influence the speed of hydraulic motor and hydraulic cylinder independent to the load prevent running away.

Hydraulic Cylinder Hydraulic cylinder is a mechanical hydraulic actuator that converts hydraulic energy or hydraulic pressure into linear displacement.

Pressure Control Valve Pressure control valves limit the system pressure to protect the system components. There are four types of pressure control valve: I. Flow Control Valve A flow control valve is used for adjusting the flow rate of a fluid in a pipeline. Directional control valve Types of directional control valve. Proportional Valve They are used in a hydraulic system that need to vary either flow or pressure to reduce lunge and shock. Cheque Q Meter They controls the returning flow in relation to the flow being directed into opposite side of the actuator.The primary sun gear is directly coupled to the hydraulic motor by the inner race of the brake clutch assembly.

If the output planet carrier is held from turning by the bearing support, the drum rotates in the opposite direction of the motor input shaft. If the ring is held stationary, the drum rotates in the same direction as the motor shaft. In the hoisting direction, the static brake remains fully applied and the input shaft rotates freely through the sprag clutch. When the motor is stopped, the load tries to rotate the winch gear train in the opposite direction.

The sprag clutch on the input shaft immediately locks up, allowing the fully applied static brake to hold the load from dropping. See Dual Brake System — Operation for a detailed description of the lowering sequence of operation. The brake valve is basically a counterbalance valve.

It contains a check valve to allow free flow of oil to the motor in the hoisting direction and a pilot operated, spring-loaded spool valve that blocks the flow of oil out of the motor when the control valve is placed in neutral. When the control valve is placed in the lowering position, the spool valve remains closed until sufficient pilot pressure is applied to the end of the spool to shift it against spring pressure and open a passage.

See Figure 1. After the spool valve cracks open, the pilot pressure becomes flow-dependent and modulates the spool valve opening which controls the lowering speed. See figures 2, 3 and 4. The static brake is released by the brake valve pilot pressure at a pressure lower than that required to open the pilot operated spool valve.

This sequence assures that dynamic braking takes place in the brake valve and that little, if any, heat is absorbed by the static, friction brake.

The hydraulic cylinder, when pressurized, will release the spring pressure on the brake discs, allowing the brake discs to turn freely. The static friction brake is a load holding brake only and has nothing to do with dynamic braking or rate of descent of a load.

In these situations, there are two steps I always complete before reaching for my test gear. The first is to conduct a visual inspection of the hydraulic system, checking all the obvious warning signs that could cause the problem in question never overlook the obvious. The second is to ask for a circuit diagram for the hydraulic system. Figure 1. Graphical Circuit Diagram. Cutaway Diagrams show the internal construction of the components and flow paths.

Because these diagrams typically use colors, shades or patterns in the lines and passages, they are very effective at illustrating different flow and pressure conditions. This makes them ideal for training purposes. The components are seen externally and are usually in a close reproduction of their actual shapes in scaled sizes. This aids in component recognition and identification. Graphical Diagrams are the shorthand system of the fluid power industry Figure 1. Graphical diagrams are preferred for design and troubleshooting purposes.

A graphical circuit diagram is a road map of the hydraulic system, and to a technician skilled in reading and interpreting them, it is a valuable aid in identifying possible causes of a problem.

This can save time and money in a troubleshooting situation. If a circuit diagram is not available, the technician must trace the hydraulic circuit and identify its components in order to isolate possible causes of the problem. This can be a time-consuming process, depending on the complexity of the system. Reason being, if the function of a component within a system is not known, it can be difficult to discount it as a possible cause of the problem. Circuit diagrams eliminate the need to reverse-engineer the hydraulic system.

This is unlikely to bother the technician because it is the machine owner who usually pays for its absence through prolonged service calls and increased downtime. Where do all the hydraulic schematic diagrams go? In the case of a mass-produced machine, the hydraulic circuit diagram should be available from the equipment manufacturer on request. If the machine is custom-built, it may be necessary to have the circuit drawn from scratch. A fluid power engineer or your preferred hydraulics supplier could provide this service.

When obtaining circuit diagrams, request both electronic dwg format and hard copy.A hydraulic winch is a pulling or lifting device with a wire rope wound around a rotating drum and a hydraulic winch motor powered by pressurized hydraulic fluid.

Hydraulic winches are often preferred over electric winches because they can operate continuously without overheating the motor. Vehicle-mounted hydraulic winches are quite common, and they operate using the power steering pump or hydraulic system of the vehicle itself. The industrial hydraulic winch is commonly used in automotive, construction, mining, railroad, marine, and oilfield applications, among many others.

Industrial hydraulic winches can have different gear configurations, depending on the demands of the application. Spur gears are most efficient and have low internal friction.

Worm gears have higher ratios and are self-braking. Planetary gears are smooth, compact, and provide good resistance to torque. Winch accessories are available such as seal kits, solenoid body assemblies, and replacement motors, as well as a hydraulic winch kit for adapting a winch to the power steering system of a particular vehicle.

Mile Marker.The winch's solenoid is its power switch and main safety device. When electricity is sent to the solenoid upon activation of the power switch, a magnetic field causes the circuit to the winch to be completed and power to be sent to the device for operation.

The solenoid protects the winch from being used without a key in the ignition. Wiring the solenoid to the winch and the switch is the final step in the installation process. Run the positive and negative motor wires from the winch to the solenoid. Fasten these wires to the correctly labeled terminals on the solenoid by backing off the terminal nuts and securing the ring connectors over the terminal bolts. Tighten the terminal nuts back down. Connect the positive and negative battery wires to the solenoid's terminals marked for the battery.

Pay attention to the proper polarity.

Run the solenoid's battery wires to the vehicle's battery and fasten them to the correct polarity terminals. These wires are typically color coded to match the solenoid terminals. If they are not, you must trace them back to their source to determine their polarity. Then make the connections to the solenoid based on this information.
