The two-end busy excavator loader is a standard mechanical vehicle. Different working equipment is installed at both ends of the vehicle body. Generally speaking, one side is equipped with the excavator bucket and the other side with the loader bucket. It is actually a single device composed of three construction equipment (a tractor, a loader and an excavator). The core structure is the tractor, which is designed to be able to travel freely on various rough terrains. During construction, the operator only needs to rotate the seat once to change the working end.
Characteristics
Overall performance characteristics
Multi-functional integration: It combines the functions of excavation and loading. One device can complete multiple operations, improving the utilization efficiency and economy of the equipment. It is suitable for scenarios where excavation and loading operations need to be carried out simultaneously, such as construction sites and road construction.
Compact structure: It can move freely in narrow Spaces, which gives it a significant advantage in some construction sites with limited space, such as small-scale building projects in cities and construction on narrow streets.
Wide range of applications: It can be used in earthwork construction of highway, railway, building, hydropower, port, mine and other construction projects. It can also be used for digging ditches to lay pipelines and underground cables, laying the foundation of buildings and establishing drainage systems, etc.
Component characteristics
Power system: Equipped with a high-power engine, it features green, energy-saving and more environmentally friendly characteristics. Some parts adopt an integral hydraulic torque converter, which is not suitable for high temperatures and is easy to maintain. There is also a split fixed-axis transmission torque converter, which is more convenient for maintenance and has more obvious heat dissipation.
Frame and travel: A articulated frame is adopted, with a small turning radius. Some models adopt widened tires to enhance grip, increase handling, and shorten braking distance at the same time. Stepless speed change, full hydraulic steering, and easy and convenient operation.
Working device: It has a large lifting force, automatically flattens the high-level discharge, shortens the action time of the working device, and improves the overall operation efficiency of the machine. Ultra-high level unloading, wide-body hopper shovel transportation efficiency is higher, and the working device has a shorter working time. The mid-mounted excavation device and the wing-type outriggers offer greater stability than other forms of excavation devices when breaking rocks and conducting deep excavations.
Cab: Some cabs feature thickened hoods with sliding Windows, which have low resonance, are sturdy and durable, and have good ventilation. The enlarged cab, safety glass and luxurious shock-absorbing seats are adopted to provide the operator with a better working environment.
Application scenarios
Construction of buildings
On construction sites, the two-end busy excavator loader can be used for foundation excavation, earthwork transportation, site leveling and other tasks. For example, when laying the foundation for a building, excavation operations are carried out, and the excavated soil is loaded and transported away. During the construction process, the loader part can also be used for the transportation and stacking of building materials.
Road engineering
In road construction, it can be used for filling and excavation in subgrade engineering, as well as for collecting and loading materials in asphalt mixture and cement concrete yards. In addition, it can also perform operations such as pushing soil, leveling the ground and towing other machinery.
Underground engineering
It is mainly used for digging ditches to arrange pipelines and underground cables, etc., providing convenience for the construction of underground projects.
Precautions for Use
Personnel requirements: The driver must be trained and qualified before operating the excavator and shovel integrated machine, and must use, operate and maintain it in accordance with the requirements of the manual.
Pre-use inspection: Before using the new equipment, it is necessary to check whether all exposed connectors and fasteners are tightened. Check the engine oil, water, fuel and the lubrication conditions of each lubrication point as required.
Running-in requirements: Newly manufactured two-end busy loaders must be running-in in accordance with the running-in regulations before being put into use. For example, the running-in period for earthwork operations is 30 hours, etc.
