Introductions Of ZM17 Home Excavation Multi Function New Small Excavator 1.7 Ton Compact Mini Excavators 

Small excavators are widely used in greenhouse orchards, mountain ditches, rural renovation, indoor and outdoor, construction projects, road finishing and other working conditions.

Generally, it is composed of power device, transmission device, walking device and working device. Principle: Use the bucket to excavate the material above or below the bearing surface, and load it into the transport vehicle or the earth-moving machine unloaded to the stockyard. A self-propelled mining machine that uses a bucket to shovel exfoliated material or minerals from the working face and transport it to a discharge location for unloading. History: It has been more than 130 years since the first manual excavator came out. During this period, it has experienced from steam-driven bucket rotary excavator to electric drive and internal combustion engine-driven rotary excavator, and fully automatic hydraulic excavator using electromechanical-hydraulic integration technology. gradual development process.

1. Preheating of the hydraulic device. When the temperature of the hydraulic oil is low, rapid operation will cause damage to the hydraulic device.

1.1. The small excavator engine runs at a medium speed, operates the bucket, and preheats;

1.2. Jack up the machine to rotate the crawler, and preheat the left and right travel motors respectively;

1.3. Then, raise the speed of the engine to the highest, and make the bucket and stick work continuously for 5 minutes;

At the same time, the safety of the surrounding environment should be fully paid attention to during the warm-up operation. When the temperature is low, the reaction of people will be relatively slow, so it is necessary to prevent people and objects around them during warm-up.

Second, the preheating of the small excavator engine, the first step in getting on the car, the engine should be started and run at low speed for 5 minutes. At the same time, the following inspections should be carried out during the warm-up process of the small excavator engine:

2.11. Whether the oil warning light is off;

2.2. Whether there is oil leakage or water leakage;

2.3. Whether the sound of the engine and the color of the exhaust are normal;

2.4. Whether the charging indicator light is off;

2.5. Whether each part of the machine is abnormal.
