Excavator attachment - hydraulic pliers

Publish Time: 2023-01-05
After the hydraulic excavator gradually became popular, it has now developed into the main force of demolition. Some low-rise, easy-to-demolition structures can be demolished to some extent, even with just a standard bucket. In addition, the mobility of the excavator is much stronger than that of the heavy crawler crane. It can drive to the vicinity of the building, or even climb the stock pile for operation, which makes up for the lack of arm length to a certain extent. far beyond the reach of a crane. The hydraulic pulverizer equipped with the excavator uses hydraulic power to work, not only the working position is accurate, but also does not need to swing back and forth, which greatly improves the demolition efficiency of high-rise buildings compared with the wrecking ball. In addition to common breakers, there are also various hydraulic pulverizers and hydraulic shears. Although the breaker uses hydraulic power, it uses impact to destroy brittle materials, such as concrete, blocks, etc., the application range is not wide enough, and it only destroys the structure and collapses the building. When further processing construction waste, it destroys the efficiency of concrete Not high. At the same time, it is powerless for non-brittle materials such as steel bars, steel beams, and various pipes. Hydraulic crushing pliers are a little different, completely relying on pressure or shear force to destroy, accurate, efficient, and convenient for material recovery.

Various hydraulic pulverizers are mainly used for concrete. Concrete is characterized by high compressive strength, but not high tensile strength and shear strength. When locally subjected to large compressive stress, it is easy to generate tensile stress on the edge and cause damage. Therefore, reinforced concrete structures are commonly used in buildings, and steel bars are used to withstand tensile stress. When dismantling, it is necessary to do the opposite, crushing the concrete in the direction perpendicular to the steel bar, so that the steel bar cannot function, and by breaking the concrete, the concrete and the steel bar are separated. This is useful not only when collapsing buildings, but also when further processing these construction wastes, efficiently separating the steel and concrete of various components for easy recycling.
Excavator hydraulic pliers, also known as excavator breaking pliers, demolition breaking shears. In recent years, it has been gradually recognized by customers in China. It has high efficiency in crushing concrete during demolition and relocation, and it is used with a breaker to avoid the disadvantages of high risk and high cost of manual operation. Hydraulic tongs are composed of tongs body, oil cylinder, movable jaw and fixed jaw. The hydraulic system exerts movement pressure on the hydraulic cylinder, so that the movable jaw and the fixed jaw of the hydraulic tongs can realize the opening and closing movement to achieve the crushing effect. All crushing tongs are equipped with a powerful cylinder that uses different pressures to handle different working conditions, and all models are equipped with rebar cutting blades. Secondary demolition refers to the crushing of concrete after the initial demolition to facilitate loading and transportation for recycling. The effective method for secondary demolition is to separate the steel bars. Extremely strong tooth system, high-quality alloy steel, and high-performance oil cylinder make up the HC series of crushing pliers.
Features of excavator crushing pliers
1. High efficiency, equipped with steel bar cutter, crushing pliers can perform two operations at the same time, crushing concrete and cutting steel bars.
2. High versatility, it can be installed on various brands and models of excavators, easy to disassemble and assemble, and can quickly replace other attachments, so that one machine can be used for multiple purposes.
3. The operation is convenient and the operation is mechanized. The steel bar is separated from the concrete block, bent and loaded onto the car, which improves the work efficiency.
