Jehel is renowned for its advanced hydraulic truck tipplers, designed to offer superior performance and reliability. Understanding the sophisticated hydraulic system behind these truck tipplers highlights why Jehel is a leading supplier in this industry.

Hydraulic Truck Tippler Working Philosophy

The primary function of a hydraulic truck tippler is to raise and lower a truck-loaded platform using a pair of telescopic lift cylinders. Here’s how the hydraulic circuit works:

  1. Electric Motor: Acts as the prime mover, providing necessary torque to the pump.
  2. Tandem Pump: Delivers constant pressure and flow to the system.
  3. Gate Valve: Prevents flow to the pump during servicing.
  4. Pressure Relief Valve (PRV): Sets system pressure limits and releases excess pressure.
  5. Directional Control Valve: Controls the hydraulic cylinders’ movements.
  6. Throttle Check Valve: Allows controlled platform descent to prevent rapid lowering.
  7. Safety Mechanisms: Includes ball valves and hose fail safety valves to ensure safe operation during emergencies and component failures.

Features of Jehel’s Hydraulic Truck Unloaders

Jehel’s hydraulic truck unloaders are built to accommodate various truck/trailer models with capacities ranging from 40 tons to 100 tons and platform sizes from 8.5 meters to 18 meters. Key features include:

  • Anti-skid Chequered Plate: Ensures safe positioning of the truck/trailer.
  • Heavy-Duty Lift Cylinders: Capable of tilting the platform up to 55°.
  • Retractable/Fixed Back Stoppers: Secure the rear wheels.
  • Hook Chain Arrangement: Holds the front axle of the truck/trailer securely.
  • Control Panel: Desk-type control panel for easy operation, powered by a hydraulic power pack.

Introduction to Hydraulic Truck Tipplers

Hydraulic truck tipplers are essential equipment in industries where bulk material handling is a key operational requirement. They are designed to lift and tip loaded trucks, allowing the contents to be efficiently unloaded. This mechanized process not only saves time but also reduces labor costs and enhances workplace safety.

Understanding the Hydraulic Circuit

The heart of the hydraulic truck tippler lies in its hydraulic circuit, which comprises various components working in harmony to lift and lower the truck platform. Here’s a detailed look at how each component contributes to the overall operation:

Electric Motor

The electric motor is the driving force of the hydraulic system. It provides the necessary torque to the tandem pump, ensuring that the system receives a consistent flow of hydraulic fluid. The motor runs at a specified speed to maintain the required flow rate, which is crucial for the smooth operation of the hydraulic cylinders.

Tandem Pump

The tandem pump is a critical component that delivers a constant flow of hydraulic fluid to the system. It ensures that the hydraulic cylinders receive the pressure and flow needed to lift and lower the truck platform. The pump’s efficiency directly impacts the performance of the hydraulic truck tippler.

Gate Valve

A gate valve is placed between the hydraulic oil tank and the pump. This valve is essential for isolating the pump during maintenance or servicing. By closing the gate valve, the flow of hydraulic fluid to the pump is stopped, preventing any potential damage. It is important to ensure that the gate valve is open before operating the pump to avoid running it dry.

Pressure Relief Valve (PRV)

The pressure relief valve (PRV) is a safety mechanism designed to protect the hydraulic system from excessive pressure. Positioned between the pressure line and the tank line, the PRV sets the maximum pressure limit for the system. If the pressure exceeds this limit, the PRV releases the excess pressure, preventing potential damage to the system components.

Directional Control Valve

The directional control valve is a solenoid-operated valve that directs the flow of hydraulic fluid to the lift cylinders. This valve is responsible for controlling the movement of the truck platform, enabling it to rise and lower as required. The valve’s precise operation ensures smooth and accurate control of the platform’s position.

Throttle Check Valve

The throttle check valve is installed in the platform up line to regulate the flow of hydraulic fluid. When the platform is being lifted, the valve allows free flow to the cylinders. During the lowering process, the valve restricts the flow, ensuring that the platform descends at a controlled rate. This prevents the platform from lowering too quickly, which could cause instability and potential accidents.

Safety Mechanisms

Safety is paramount in the design and operation of hydraulic truck tipplers. Several safety mechanisms are incorporated to ensure the safe operation of the system:

  • Ball Valve: In the event of a power failure, the ball valve allows the hydraulic fluid to be manually released from the cylinders, lowering the platform safely.
  • Hose Fail Safety Valve: This valve is added to the lift cylinder port to prevent the platform from free-falling in case of a hose or pipe failure.
  • Pressure Relief Valve in Down Line: This valve prevents excessive pressure in the platform down line, protecting the mechanical system from damage if the operator mistakenly activates the platform down switch.

  • Heavy-Duty Lift Cylinders: These cylinders can tilt the platform up to 55 degrees, allowing for efficient unloading of the truck’s contents.
  • Retractable/Fixed Back Stoppers: The back stoppers secure the rear wheels of the truck, preventing any unintended movement during the tipping process.
  • Hook Chain Arrangement: A robust hook chain arrangement holds the front axle of the truck or trailer securely, adding an extra layer of safety.
  • Control Panel: The desk-type control panel simplifies operation. All functions are actuated through a hydraulic power pack using push buttons on the control panel, making the system user-friendly and efficient.
