Pull arm tops

The pull arm top is designed and manufactured by introducing and absorbing European advanced technology, with stable performance and good workmanship. The design of the pull arm is safe and reliable, light and strong, with high inclination and quick loading and unloading.

The hook arm and its linkage frame on the pull arm are made of Baosteel customized plates; the subframe is made of WISCO customized plates. Both of these two types of plates are high-strength welded plates with high tensile strength and good welding performance. Therefore, in the forming process, the ordinary bending machine cannot be folded, and through cooperation with two steel mills, a roll forming die is produced, and the pull arm profiles of different specifications are made. The top of the pull arm is not only about the selection of materials and quality, but also the molding of the mold directly ensures the machining accuracy of the parts.

The four parts of the upper part of the pull arm are all boring and processed, and are completed on a high-precision three-axis CNC gantry milling and boring machine. All the inner hole processing only needs to be clamped once, which reduces the processing error and ensures the shape tolerance of each hole and the consistency between the holes. Positional accuracy such as axiality, parallelism, etc. Therefore, the interchangeability of products is ensured, and the assembly efficiency and assembly quality are improved.

The finished pulling arm should be tested twice. One is the action function test. The rotation between each component is stable, and there is no eccentric wear, eccentric load and various assembly stresses. The hydraulic test bench is used to load the pulling arm. The hydraulic system is cleaned, the impurities in the hydraulic system are filtered, the entire hydraulic system is kept clean, and the various moving parts of the pull arm are lubricated, so that each component is always in good working condition. The second is the load test. It has a multi-functional adjustable load platform. According to the hook structure of the hook and the hooking capacity of the hook, it is equipped with the corresponding load weight for testing. The load weight is greater than 10% of the load. Ability testing, testing the tightness of pipelines and the reliability of the pull arm frame, to ensure a 100% pass rate.

(1) Chassis

The bottom frame is made of special customized profiles and is connected with the chassis of the vehicle. The arrangement of the hinge points between the lift frame and the bottom frame follows a principle, that is, the hinge point is separated from the box bearing point of the lift frame, which is important for increasing the system. The lifting capacity and stability have a very good effect. In addition, steel rollers installed on both sides of the chassis can minimize the frictional resistance generated during the sliding process of the box.

(2) Linkage frame

The linkage frame is entirely made of Baosteel custom-made profiles. Bearings used at the flip shaft are made of high-quality wear-resistant copper/aluminum alloy. When the lift box function is running, the lift frame is combined with the lift arm.

(3) Fixed seat

The fixed seat is a hollow structure, made of high-quality high-strength profiles and cast steel parts welded together. The cylinder connections (steel castings) in the frame can well withstand the forces generated during the lifting of the box and the process of dropping a fully loaded box. Even if the box support has been connected to the rear of the lift arm, the lift arm can directly transmit the lifting force required in the process of lifting the box.

(4) Hook arm

The hook arm has a double welded hollow structure, and the connecting telescopic arm adopts a slider made of synthetic material, which can reduce the wear to a minimum. The hook handle adopts the detachable structure of the draw hook. The advantage of this structure is that draw hooks of different heights can be selected according to the size of different boxes. Another advantage of this design is that once the hook is damaged, it can be easily disassembled and replaced, and all operations can be completed in a very short time.

Pull arm hook box

The key parts such as the hook box body are made of high-strength, wear-resistant steel plate, and its effective strength is twice that of ordinary Q345B low-alloy high-strength plate; in addition, high-density shot peening, airless spraying for high-strength marine anti-corrosion and wear-resistant plates is used. Corrosion-resistant primer and other measures have greatly improved the comprehensive service life of the entire equipment.

The equipment is easy to install and debug. There are no special requirements for the use site and workshop, and it can be moved at any time as needed. The entire product series is standardized design, making it compatible with various types of detachable garbage trucks with high applicability. .

The side plate is made of the whole plate, without exposed reinforcing ribs, and the appearance is smooth and beautiful. The inner and outer surfaces of the box are treated with high-density shot peening (the treatment effect reaches Sa2 level); using the airless spraying process, we apply the special anti-rust, anti-corrosion and wear-resistant post-slurry primer for shipbuilding in the bottom treatment of the equipment. , greatly improving the anti-rust ability and wear resistance; the welding of the equipment is beautiful and smooth, without welding defects such as leakage welding, cracks, slag inclusions, pores, undercuts, and spatters. All exposed ferrous metal surfaces are rust-resistant. The paint film is smooth and flat, without flow marks, bubbling, wrinkling, cracks and obvious brush marks.

In order to prevent leakage more effectively. The rear door is locked by a hydraulic locking device that takes power from the detachable garbage truck in the compartment, and the hydraulic cylinder will not automatically expand and contract when bumped and impacted. The locking lugs are coaxially welded together to lock both sides synchronously. The rear door hinge ear hole is an oblique long hole, which makes the rear door more effective in full contact with the sealing strip. Because NBR has excellent oil resistance, high wear resistance, good heat resistance and strong adhesion. Therefore, we use the integral high-wear NBR oil-resistant structure sealing strip, which has excellent sealing performance, can effectively prevent the leakage of sewage and the emission of odor, and avoid the waste of garbage in the process of hoisting and transporting garbage cans. Sealed, can effectively avoid secondary pollution.
