Excavator loading is one of the most common operations projects, due to the rotation angle of the site topography and other factors excavators, not as long as the truck (herein after eight rounds of the middle finger, liberation, Dongfeng transport vehicles or tractors and other projects, these are referred to as “truck “) near the excavator can be, the relative position of a parked truck and excavator is also very particular, which directly affects the excavator loading efficiency.
Listed below are some common scenarios:
1: truck parked in front of the excavator
This is the most common case, the excavator digging the soil around the front and sides of the truck parked in front of the rotary excavator basically less than 90 °, natural speed, high efficiency, can meet if not reversing lorry drivers good, it does not work. For example, only into a car, reversing that time is wasted, and, if a vehicle is poured from the same location, then the excavator on the addition of one thing is to clean up the rear of the truck I soil, so that the next car can close.
The ideal situation is to have two cars side by side , put the car A , B side by side into the car , A car drove off after filling , we can immediately loaded B car , then they can position C car A car from the original pour . Such loading , saving time reversing the highest loading efficiency.
But in most cases the truck drivers do not understand this, so the right time to guide the truck parked in the right position , remember when loading the speaker is the only means of communication , but before the car is not filled , can not honk if you honk , truck drivers will be filled with mistaken and drive away .
The second case : truck parked on the side digging machine
Truck parked on the side was divided into two cases, one , excavators and trucks at the same height ( no table ) . 2 , excavators higher truck (with stand ) . When the table easier , as long as the truck by how close they rely on how close the angle of rotation around the excavator are basically 90 °, if you want to achieve maximum efficiency , it is best to trucks lined up like train cars as a pick one . If there is no table of cases, it should be noted that trucks can not rely excavator too close, too close will affect the swing , hit the tail excavator hit even less will affect the boom lifting height .
However, in practice, we often encounter when excavators , trucks have been docked at the edge of a crawler excavators . Lead excavator driver can not make rotary digging machine , only to back away . I give you a suggestion , which is in the right place heap a shovel , naturally, not too close to the truck .
The third case : van parked behind the excavator
When van parked behind the excavator , there are also two cases, there is no table and table . No table , digging soil behind , in front of the vehicle mounted , that is to rotate 180 °, has a great influence on the natural loading speed. Then lorry reversing most pay attention, do not be too close , otherwise the car will hit the tail digging machine . And the tailgate truck cargo box , digging machine will block the driver’s line of sight , do not see the arrival of the front of the box , it will cause dissatisfaction or mounted bucket truck cab caught situation . When table , trucks and in the back, is commonly known as anti-loaded soil, this situation is most troublesome , because you have to consider while loading excavator retreat , this is probably the least efficient loading conditions .
Trucks and excavators position will affect the efficiency of the excavator loading, but many times, we can take the initiative to adjust the relative position, as long as trucks and excavators with the good, in most cases, three cases can slowly adjust becomes the second, and the second may be slowly adjusted to become a first.
