Eastwind 8m³ Arm-Type Garbage Truck

Vehicle Functional Advantages

Product Features:

Articulated garbage truck, capable of multiple bins per vehicle, with self-unloading function, ensuring safety, stability, and reliable performance. The garbage bins are available in different configurations, including articulated arm and dual-purpose pit/ground models. Optional sealed lids can be added to prevent leakage and dust pollution, catering to various environmental usage requirements. Its working principle combines advanced technology from domestic and international similar waste collection trucks, fully utilizing hydraulic technology to ensure a rational vehicle design structure, excellent performance, and easy operation.

Product Structure:

(1) Control Device - The buttons and levers on top are used to control various actions during the self-loading and unloading process.

(2) The main hydraulic cylinder and boom are actuated by pushing the control rod forward (backward), causing the main cylinder to extend (retract), and driving the boom to swing forward (backward), achieving the purpose of lifting (lowering) the box. During empty-box operation, the quick adjustment feature can be utilized to quickly swing the boom backward and lower the box. At this point, push the control rod backward while pressing the button on the control rod.

(3) Telescopic hydraulic cylinders and boom - The telescopic cylinders can be controlled via buttons on the control device to drive the boom, either lifting or lowering the body. Depending on requirements, the telescopic booms can move together or independently.

(4) Support hydraulic cylinders and legs - During loading and unloading, rear support legs are used to prevent the vehicle from leaning backward, providing stability. Operation is via buttons on the control device. Due to potentially uneven ground, the left and right support legs can also be moved independently.

(5) Box Retainer - Prevents the box from sliding forward or to the sides, ensuring safe transport. The front retainer can be adjusted forward and the side retainer moved outward by rotating the handle, according to the bottom dimensions of the box to accommodate different box sizes.

(6) Chains - Vehicle chains are available in 3 specifications: single chain, double chain, and adjustable chain. Choose the appropriate chain based on the different box types.

(7) Reversing Hook

When the arm garbage truck needs to dump the material directly from the container, the flip hook is activated, at which point it must be in the upward position (flip position), and it is directly pushed by the cylinder. The safety device of the flip hook is automatically controlled by a cam. In this manner, when the flip hook is in the upward position, the container's pivot axis is disengaged, and when flipped, the pivot axis is caught by the flip hook.

The unloading process of the material must be handled externally; the control lever should be pushed upwards. When the flip hook is in the upper position, the cab control is interrupted; the unloading process can only be controlled by the external lever.

● Operation Process:

(1) Entire body loading of the arm-type garbage truck

Reverse the vehicle, positioning the rear of the car facing the container. Extend the support legs to the ground; adjust them individually if the ground is uneven. Ensure the flip hook is in the downward position. Swing the main arm backward (quick adjustment) to position the container between the two main arms. Adjust the telescopic arm to place the chain directly above the center of the container. Adjust the chain to fit the container size and hang it from the container's lifting ears. Swing the main arm forward until the container is on the loading surface. Retract the support legs. Position the flip hook in the upward position.

(2) Entire body unloading of the arm-type garbage truck

Position the vehicle so the rear faces the unloading area. Extend the support legs to the ground; adjust individually if the ground is uneven. Place the flip hook in the downward position. Exit the cabin, check that the safety hook or chain hook is properly positioned. Swing the main arm backward until the container is close to the ground. Extend the telescopic arm to the distance where the container can swing freely at the rear of the vehicle. Swing the main arm backward until the container touches the ground. Exit the cabin and remove the chain. Park the vehicle in the transport position.

(3) Unloading of Materials Inside the Arm-Type Garbage Truck's Compartment

The vehicle's rear faces the unloading area. The flip hook must be in the up position (flip position). Extend the support legs, ensuring the ground is solid and stable. Exit the cabin, check that the safety hook or chain hook is in the correct position. Verify that the container's flip pivot is locked by the flip hook. Operate the external control lever to swing the main arm backward until the container is empty.

Section 3: Power Transmission System and Hydraulic Drive Principle of the Arm-Type Garbage Truck

The power for the hydraulic system is derived from the car's engine, powered through the clutch to operate the transmission. The activation of the power take-off is controlled by an electromagnetic air control valve. As the power take-off operates, the connected drive shaft and plunger hydraulic pump also rotate. The hydraulic pump rotates for approximately 5 to 10 seconds before it starts to affect various operational processes. The movements of various hydraulic cylinders are achieved through the hydraulic system. The system boosts the oil from the reservoir using a plunger pump, passing it through a filter to the proportional manifold valve, and then to the drive unit via individual functional blocks. These functional blocks are controlled by the operating device and an air-driven remote control unit. Additionally, compressed air from the car's chassis is supplied to the cylinders through a quick exhaust valve.
