The reason why excavators can operate flexibly in multiple fields such as construction, mining, and agriculture largely depends on various types of attachments with different functions. These attachments are connected to the excavator arm through a quick connect device and can be replaced at any time according to different operational needs, greatly improving the utilization rate of the equipment. Here are several common excavator attachments:
The breaking hammer is one of the most commonly used attachments for excavators, with its core components being the hammer head and hydraulic drive system. During homework, hydraulic oil drives the piston to move back and forth at high frequency, driving the hammer head to violently impact hard objects such as concrete pavement, rocks, building walls, etc., achieving crushing operations. The breaking hammer can be divided into light, medium, and heavy types according to weight. Light type is suitable for breaking walls in urban demolition, medium type can be used for breaking surface rocks in mines, and heavy type can cope with the disintegration of hard rocks such as granite. Its advantage lies in high crushing efficiency, precise control of crushing range, and reduced impact on surrounding structures.
Hydraulic pliers are mainly used for cutting and dismantling metal structures, and there are two common types: crushing pliers and shearing pliers. The crushing pliers are closed by two toothed jaws to bite and squeeze the steel bars in the concrete, while crushing the concrete. They are suitable for separating steel bars and concrete in building demolition; Cutting pliers are specialized in cutting steel materials such as steel beams, columns, and pipes. They have high blade hardness and strong shear force, making it easy to cut larger diameter metal materials. Hydraulic pliers are widely used in demolition projects, which can efficiently handle metal structures and reinforced concrete components, and there is relatively less noise and dust during the operation process.
The excavator bucket is the basic accessory of the excavator, which can be divided into standard bucket, reinforced bucket, and special bucket according to different operating scenarios. The standard excavator bucket is suitable for excavating and loading general soil. The bucket body is made of wear-resistant steel plate and has a lightweight structure; The reinforced excavator bucket has added wear-resistant strips or alloy blocks to the easily worn parts such as the bucket lip and bottom, which is suitable for excavating hard materials such as gravel and sand; Special digging buckets, such as inclined digging buckets, can adjust the bucket body angle through hydraulic devices, facilitating fine operations such as slope trimming and ditch formation. The capacity of the excavator bucket varies from a few cubic meters to tens of cubic meters, and needs to be selected according to the excavator model and operating volume.
Wood grabbing tools are mainly used to grab bulk or bundled materials such as wood, steel, stone, etc. According to the grabbing method, they can be divided into mechanical grabbing tools and hydraulic grabbing tools. Mechanical wood grabbing uses a linkage mechanism to achieve claw opening and closing, with a simple structure and low cost, suitable for grabbing lightweight materials; The hydraulic wood gripper is driven by a hydraulic cylinder, which has a high gripping force and a large opening and closing angle. It can grip heavy logs, steel pipes, scrap steel, etc., and the gripping action is smooth and not easy to slip off. In places such as wood processing plants, steel markets, and scrap steel recycling sites, grabbing wooden objects can significantly improve the efficiency of material loading, unloading, and handling.
