The control valve is actually a device which directs the fluid to the actuator. This device would comprise steel or cast iron spool which is positioned in a housing. The spool slides to different locations inside the housing. Intersecting grooves and channels direct the fluid based on the spool's location.
The spool has a neutral or central position that is maintained by springs. In this particular location, the supply fluid is returned to the tank or blocked. When the spool is slid to a direction, the hydraulic fluid is routed to an actuator and provides a return path from the actuator to tank. If the spool is transferred to the other side, the supply and return paths are switched. When the spool is allowed to return to the center or neutral position, the actuator fluid paths become blocked, locking it into place.
The directional control is typically intended to be stackable. They usually have one valve per hydraulic cylinder and a fluid input that supplies all the valves within the stack.
To be able to avoid leaking and handle the high pressure, tolerances are maintained really tight. Normally, the spools have a clearance with the housing of less than a thousandth of an inch or 25 µm. So as to prevent distorting the valve block and jamming the valve's extremely sensitive parts, the valve block will be mounted to the machine' frame with a 3-point pattern.
A hydraulic pilot pressure, mechanical levers, or solenoids could actuate or push the spool left or right. A seal enables a part of the spool to protrude outside the housing where it is accessible to the actuator.
The main valve block controls the stack of directional control valves by capacity and flow performance. Several of these valves are designed to be proportional, like a proportional flow rate to the valve position, while other valves are designed to be on-off. The control valve is among the most sensitive and expensive components of a hydraulic circuit.
Counterbalance lift trucks are actually common pieces of machinery in the material handling business. They are actually popular machinery utilized in warehouses and factories all over the globe. The leading lift truck producers like Mitsubishi, Linde and Toyota all construct counterbalance lift trucks. They are presented in a range of fuel choices like for example diesel, electric or gas. Normally, a counterbalanced forklift truck comprise the following parts:
The section for the operator referred to as the "cab" and houses all of the levers, pedals, steering wheel and dashboard which contains certain readouts plus various switches. The frame of the lift truck is the base intended for the various components of the equipment consisting of the power supply, the wheels, the axles, mast and the counterweight. The frame might also have hydraulic fluid tanks and fuel tanks made as part of its assembly. The Mast is the vertical assembly that does most of the work lowering and raising the forklift's load.
The counterweight is a heavy mass of cast iron which is connected to the back of the forklift truck frame. The counterweights' purpose is to offset all the load being lifted. With an electric lift truck, the large lead-acid battery itself can function as part of or all of the counterbalance. The Power Supply may have an internal combustion engine that can be powered by LP gas, CNG gas, diesel or gasoline. Electric forklifts are driven by either fuel cells which provide power to electric motors or a battery. The electric motors can be either AC or DC types.
Fork accessories are numerous types of material handling attachments that are available consisting of roll clamps, container handlers, carpet poles, pole handlers, side shifters, multipurpose clams, carton clamps, slip-sheet attachments and fork positioners.
The counterbalanced lift truck is the best electric lift truck to use for parking pallets closely together. Counterbalanced forklifts offer several advantages over straddle-leg styles and fork-over designs. They do have several drawbacks though. A counterbalanced forklift could carry pallets straight off the floor as there are no stabilization legs to get in the way. The main disadvantage of this particular model of forklift is that the weight capacity and lift height would usually be less compared to the other styles.
