            The application range of excavators is very wide, and various operations such as crushing, dismantling, and grabbing can be completed by replacing different auxiliary devices, such as hydraulic hammers, hydraulic shears, bulldozers, and buckets.


            1. Backhoe operation


            Backhoe operations are generally carried out below the ground, mainly through excavation. (1) Use the stick and bucket together for excavation. When the hydraulic cylinder of the bucket is at a 90 ° angle to the connecting rod and the hydraulic cylinder of the stick is at a 90 ° angle to the stick, a large digging force and efficiency can be achieved. (2) Try to keep the direction of the bucket teeth consistent with the excavation direction, reducing excavation resistance and bucket tooth wear.


            2. Shovel operation


            The shovel operation is generally carried out above the ground, and the rotation of the bucket is opposite to that of a backhoe. Use a stick hydraulic cylinder to scrape the ground. The excavation force during the front shovel is smaller than that during the back shovel.


            3. Trenching operations


            By configuring buckets corresponding to the width of the ditch, the tracks on both sides can be parallel to the edge of the ditch to be excavated, allowing for trench excavation operations. When digging a wide ditch, first dig both sides and then remove the middle part.



            The characteristics of rubber tracks in excavators include light weight, low vibration, low noise, strong adhesion, good ground adaptability, and no damage to the road surface; Especially suitable for urban road construction.


            The basic structure of rubber tracks and steel tracks is the same, usually composed of guide wheels, support wheels, drive wheels, support wheels, tracks, and walking frames. The main differences and characteristics are:


            (1) Rubber track is a continuous track made of rubber molding, reinforced with fabric and multiple steel wire ropes at the center, with spikes on the outer side and transmission components on the inner side. Steel transmission components are embedded in vulcanized rubber belts. The main parameters of rubber tracks are pitch, number of sections, track width, pattern style, and embedded metal part style.


            (2) The driving wheel is installed on the walking reducer to coil the track and increase the operation of the machinery. The driving wheel used for rubber tracks adopts a convex tooth profile with a pitch of 128mm. During the operation of the track, there is bending stress, which can cause fatigue damage to the track, so the driving wheel diameter is not easily too small.


            (3) The supporting wheels, supporting wheels, and guide wheels are separated on both sides of the track teeth and pressed against the rubber surface. To prevent damage caused by cutting and severe compression of the rubber on the wheel flange, the wheel flange is wider. Due to the higher tread teeth, the wheel body is larger.
