gd55光大在老品牌Excavator operation technology


First, check the surrounding conditions. When rotating, pay attention to surrounding obstacles and terrain for safe operation; During operation, confirm the front and rear directions of the track to avoid tipping or collision; Try not to face the final drive towards the excavation direction, otherwise it may damage the walking motor or hose; During the homework process, ensure that the left and right tracks are in full contact with the ground to improve the dynamic stability of the entire machine.


Slope leveling operation


gd55光大在老品牌During the surface finishing process, place the machine flat on the ground to prevent it from shaking. Grasping the coordination of the movements of the boom and the stick, and controlling their speed, is crucial for surface finishing.



Loading operation


gd55光大在老品牌The body should be in a horizontal and stable position, otherwise it is difficult to precisely control the rotation and unloading, thereby prolonging the working cycle time; Maintain an appropriate distance between the vehicle body and the truck to prevent collision with the truck at the rear of the vehicle during a 180 degree turn; Try to use left-handed installation as much as possible, with a wide field of view and high work efficiency. At the same time, correctly grasp the rotation angle and reduce rotation time; The position of the truck is lower than that of the excavator to shorten the lifting time of the boom and have good visibility; Loading sand and stones first, then enlarging the stones can reduce the impact on the tree trunk.


Effective mining methods


gd55光大在老品牌When the bucket cylinder is at a 90 degree angle to the connecting rod, stick cylinder, and stick, the digging force is greater. When the bucket teeth are at a 30 degree angle to the ground, the excavation force is better, that is, the soil cutting resistance is small; When excavating with a stick, ensure that the angle range of the stick is between 45 degrees in the front and 30 degrees in the back. The simultaneous use of boom and bucket can improve excavation efficiency.


Excavation of rocks


Excavating rocks with a bucket can cause significant damage to the machine and should be avoided as much as possible. When excavation is needed, the position of the machine body should be adjusted according to the direction of the rock cracks, so that the bucket can be smoothly inserted for excavation; Insert the bucket teeth into the rock crevices and use the digging force of the bucket rod and bucket to excavate (pay attention to the sliding of the bucket teeth); When using a hydraulic excavator to lift, the unbroken rock should be broken first, and then excavated with a bucket.


Lifting operations


When performing lifting operations on hydraulic excavators, confirm the surrounding conditions of the lifting site, use high-strength hooks and steel wire ropes, and use specialized lifting equipment as much as possible; The operation mode should be micro operation mode, and the actions should be slow and balanced; The length of the sling is appropriate. If it is too long, the suspended object will swing large and difficult to control accurately; Correctly adjust the position of the bucket to prevent the steel wire rope from slipping; Construction personnel should try not to approach the lifted object as much as possible to avoid danger caused by improper operation.
