The hydraulic pump, hydraulic cylinder, control valves, and oil tank all play crucial roles in making the tail lift system operate smoothly. Let’s take a closer look at each of these sub-sections and explain how they work together to power a hydraulic tail lift.

Hydraulic Pump

A critical component of the lifting mechanism present in hydraulic tail lifts is an essential part that enables it to perform its intended function. The hydraulic pump is responsible for taking fluids, typically oil and pressurizing them to supply the power required for the lift.

Pump Type Positive Displacement Pump
Pump Design Hydraulic Vane Pump
Operating Principle Vane Pump Draws Fluid into chambers and then presses discharged fluid out against a pressure relief valve.
Inlet Valve:-Controlled By:-Perform Action: Solenoid Valve / Pressure Control Valves / Flow Control Valves
Outlet Valve:-Controlled By:-Perform Action: Solenoid Valve / Pressure Control Valves

The pump’s vane design consists of chambered cylinders from which fluid is drawn from the container through inlet valves and then expelled through outlet valves back into an expanding fluid volume. The expansion and contraction cause high-pressure oil that powers the hydraulic cylinder responsible for lifting or lowering loads on the platform.

Pro Tip: Regularly checking the pump’s operation and changing any worn-out components will enhance hydraulic lift longevity, minimizing expenses related to repair and replacement.

Who needs a workout when you have a hydraulic cylinder to lift all day?

As part of the vital components that make up a hydraulic tail lift, a crucial aspect is the regulation and management of fluid flow through various valves. The Valves Controls play an integral role in this process by determining the direction, flow rate, pressure and sequence in which the fluid flows within the tail lift.

A typical Control Valve found in hydraulic tail lifts is comprised of various Components such as Solenoid coils, Spool/ball valve assembly, Metering land and Check valve Assembly. In Solenoid Coil circuitry, Valve position magnet coils are used to actuate Solenoid ‘on’ or ‘off’ positions. Besides this, in these valves, either sliding spools or ball embossed seats can be used for closing or opening different ports as per requirement. An attached metering rod restricts or controls fluid flow within the hydraulic pump cylinder while check valves prevent counter-flow.

Apart from regulating hydraulic circuits, some control valves come with built-in safety features such as pressure-limiting capabilities that automatically shut down excessive pressure within the system. Additionally, Control valves with temperature sensing elements can protect against thermal damage due to overheating.

In one instance, a malfunctioning control valve was identified as the root cause of a sudden tail-lift failure at a busy loading zone. Upon inspection by technicians, it was discovered that wear and tear on specific parts resulted in inefficient operations leading to total failure. The timely replacement of faulty parts restored full functionality to the lift.

The oil tank may be full of hydraulic fluid, but it’s not as comforting as a full tank of gas during a zombie apocalypse.
