Dongfeng Duolika D7 Compartment Unloading Garbage Truck
The hook arm garbage truck, also known as a detachable container garbage truck, is mainly used for collecting and transporting various types of waste in various places such as municipal sanitation and property management. The waste container can be completely separated from the chassis. It has the advantages of a reasonable structure, simple and stable operation, high efficiency, good sealing performance, and convenient dumping. It can achieve joint operations with multiple waste containers using a single vehicle, enabling cyclical transportation and fully enhancing the vehicle's transport capacity. Achieving a single vehicle equipped with multiple containers for cyclical transfer, which is efficient, energy-saving, and cost-effective.

Performance and Advantages
1. The design is reasonable, with the hydraulic system of the arm exerting less pressure when pulling the same weight of cargo;
2. With the same chassis, our boom adapter can fit larger box lengths, fully utilizing the vehicle's efficiency;
3. The layout on the chassis is more rational, taking into account factors such as the vehicle's center of gravity, resulting in better handling;
4. Main components include: power take-off, pump, valves, and cylinders, all sourced from reputable domestic brands;
5. The superstructure is entirely made from T700 high-strength steel plate, formed and welded, offering stronger load-bearing capacity and longer service life;
6. The hook is made from thickened alloy steel, suitable for working in low-temperature environments. The hook features a live connection for easier replacement;
7. An enhanced rear support is used, transferring all the force to the main beam, with the rear support having stronger load-bearing capacity, and the cylinder not bearing the weight of the box, resulting in longer life for the rear support cylinder;
8. Cam interlocking protection is used between the main boom, lifting frame, and sub-frame. The main boom is equipped with a mechanical lock, which automatically opens after the telescopic arm is fully retracted;
9. Multiple protections for the hydraulic system:
1. The main cylinder is equipped with a bidirectional travel valve, which automatically opens when the cylinder is fully extended or retracted, preventing high pressure inside and protecting the hydraulic system;
2. Each circuit of the multi-way valve is equipped with a safety valve, with the pressure values adjusted at the factory according to the needs of each circuit, ensuring that the pressure in each circuit is within the designed range;
3. The balance valve or hydraulic lock of the cylinder is directly connected to all cylinders (mounted on the valve seat), without using intermediate oil pipes, reducing hydraulic failures and providing more comprehensive protection for the cylinders;
4. Both ends of the telescopic cylinder are equipped with joint bearings, ensuring that the telescopic arm only receives axial forces during extension and retraction, not radial forces, resulting in longer cylinder life;
5. The locking cylinder and locking hook use a floating connection, ensuring that the locking mechanism only bears vertical forces (forces from the box jumping up and down), not lateral impact forces (centrifugal forces when the vehicle turns), resulting in longer cylinder life.
10. The operating system has multiple electronic protections, preventing the superstructure from moving in case of misoperation (or incorrect operation):
1. Main boom fully lowered detection protection: Only when the main boom is fully lowered can the telescopic arm be operated for extension and retraction, and the box lock can be locked or released;
2. Box lock fully released detection protection: Only when the main boom is fully lowered and the box lock is fully released can the telescopic arm be operated for extension or retraction;
3. Rear support extended alarm protection: When the rear support is fully extended and not retracted, the alarm beeps, reminding the operator to retract the rear support after work is completed;
11. The hydraulic oil tank is enlarged to dissipate heat generated during operation in a timely manner;
12. The rear hydraulic power output uses a two-position six-way rotary valve for control, which is more convenient and faster than using two ball valves;
13. The engine, transmission, oil pump, multi-way valve, hydraulic lock, balance valve, and hoses are matched reasonably; all operations can be completed at engine idle (inappropriate matching can lead to vehicle stalling when pulling heavy boxes, engine strain, and high hydraulic oil temperature);
14. The entire superstructure is treated with shot blasting + electrophoretic coating, enhancing the strength and rust resistance of the superstructure.
