At the work site, with limited equipment, how to improve the efficiency of mini track loaders is a topic that every enterprise is tackling with. In addition to the choice of Komatsu wheel loaders and operator skills, technological advancements have also had a significant impact on productivity. There are many factors that affect loading efficiency, such as loader size, grab bucket size, lifting height, truck size, site layout, and conditions under foot.
In the construction organization, the driving route of the Cat track loader should be drawn up in advance, and unnecessary uphill ramps should be removed. For each tunnel of the excavator with bucket, there must be an empty return lane for each to avoid mutual interference when the dump truck enters and exits. All running lanes should be kept in good condition to facilitate the operation of dump trucks.
Improperly configuring the size of the loader (loading tool) on the truck (transport unit/target) may not be conducive to improving the efficiency of the work site. Many items must be considered to determine what tilt bucket size and loading height restrictions need to be met. When choosing the bucket size of the loader, we must consider the current actual and future production goals. Specific factors such as material density, production goals, peak hours, and actual idle time should also be considered. Ensuring that the loader is sized for the application and equipped with the appropriate bucket, ground engaging tools and tires is an important first step in optimizing loading efficiency.
The driver of the bucket shovel excavator should have proficient operating techniques and try to use compound operations to shorten the excavator's operating cycle time. Experienced operators can bring efficiency to the maximum. The experience, operating skills and operating knowledge of equipment operators will affect fuel consumption, productivity and the resulting fuel efficiency. A study has shown that in the same application, different operators on the same device can differ in efficiency by up to 40%.
The number of dump trucks matched with the excavator and the carrying capacity should meet the requirements of the excavator's production capacity, and the capacity of the dump truck should be of an integer multiple of the excavator's trenching bucket. At the same time, try to use the double-loading method to make the excavator fill one, and then load the next one. Since the two dump trucks are parked on the arc line within the reach of the excavator bucket, when the ditching bucket is full and the car is turned, it can be turned to be filled with another car, thereby improving the efficiency of loading.
Make sure to set the site for maximum efficiency. The truck should be placed at an angle of 30° to 45°, and the tires should be exactly on the edge of the pile. Keeping the V-shape tight and limiting the loader's stroke is the key to reducing cycle time, fuel consumption and tire wear. Ideally, there should be enough travel distance to the truck to allow the loader operator time to raise the boom to the unloading height before approaching the truck. This ensures that there is no loss of momentum and provides the fastest cycle time. The bucket chain excavator's geometry, kinematics, power, explosive force, machine speed and steering responsiveness have been comprehensively designed to effectively complete the truck loading process within a 30-second cycle. This means the ability to dig, load, drive and lift to the dumping height before the target, then safely dump and retreat for repeated operations.
