Hydraulic Excavator Operating Techniques

Nowadays, more and more drivers have a good skill in operating hydraulic excavator. Safety comes first, only the excavator operator has a good knowledge of safe operating guidelines can he guarantee the safety of the machine and himself.

Check the ambient to make sure no barriers or rough terrains will impede the excavator to make a rotation. The crawler belts should be touched with the ground completely to improve the stability of the whole machine, which will prevent rollover and collision. The digging capacity can reach the maximum when the angle between the bucket cylinder and the rod, the arm cylinder and the bucket rod becomes 90°, the cutting resistance becomes the minimum when the angle between the bucket teeth and the ground is 30°. The digging efficiency can be improved when the boom and the bucket are used simultaneously. As we all know that hydraulic excavator can be used in various constructions, so different operating techniques should be used in different operating environments.

The excavator bucket should be prevented to dig rocks as much as possible since the hard rocks will make damage to the bucket. But when there is no choice, the operator should adjust the machine’s body and make the bucket cut the rock according to its cracks. Put the bucket teeth into the cracks of the rock and use the power of the rod. The complete rocks should be cracked before digging by bucket. Keep the machine stable and balanced when doing leveling work, it is very important to make a good coordination between the arm and the bucket for leveling. When the industry excavator is used to lift heavy-duty loads, the bucket should be put in an accurate position and no person should be close to the lifting loads, which will cause accident.

Piling Rig Maintenance Guidelines

Piling rig is the best drilling tool that is widely used in engineering construction. Designed to be used in various environments, it can be used in sand, clay and silt. Generally speaking, the rated power of the drilling rig is 125-450 kW, the torque is 120-400 kN.m, the maximum diameter can be 1.5-4 m, the maximum depth is 60-90m. In order to reduce the downtime and save cost, daily maintenance of the drilling rig is very necessary and important.

Malfunction One: Lack of torque power, low speed, abnormal noise

Reasons: Insufficient hydraulic oil pressure, something wrong with motor, gear box and decelerator.

Solution: Check the hydraulic system, if it is normal, the machine parts may go wrong. Check the motor and its shaft. Dismantle the piling rig decelerator, pay attention to the component order, wash all of the bolts and other parts. Replace the damaged gears and reinstall the decelerator and motor. Solution should be made once the malfunction is found to avoid enlarging the damaged area.

Malfunction Two: Wire rope abrasion

Reasons: Lack of lubricating oil, distortion of the wire rope

Solution: Replace the wire rope bearing and paint lubricant to the rope.

Malfunction Three: The mast oil cylinder leaks fuel

Reasons: The mast cracked or the oil cylinder seal was broken.

Solution: Replace the mast and the cylinder seal.

Excavator Maintenance Guidelines

Hydraulic excavator is the best digging tool, which are used to excavate materials above or below the bearing surface of the machine. It has become one of the main construction machineries in engineering construction. Daily maintenance is an effective way to extend its service life. Daily inspection is very important to ensure the digger to work durably and efficiently. For the self-employed, the daily inspection helps reduce maintenance costs. Here are some guidelines about the digger daily maintenance that may improve your digger’s working efficiency.

Firstly, the operators should walk around the digger twice to check if there is something wrong with the chassis, and check if there is fuel oil leaking from the slewing bearing, and then the brake deceleration device and track bolt fastener. For a wheel hydraulic excavator, the operator also needs to check whether there is something wrong with the tires and its pressure.

Secondly, you need to check whether the excavator bucket teeth are abraded, which will greatly increase resistance in the process of construction and reduce the working efficiency.

Thirdly, it is an important issue to choose the right diesel oil. The type of the diesel should be chosen according to the ambient temperature. The diesel should not mix with impurities, dust and water, otherwise, it will cause wear to the fuel pump and damage the engine of the hydraulic excavator. Open the oil drain valve to draw off the water before daily operation and fill the fuel tank after the inspection. The air in the pipeline should be removed after the fuel in the engine is used up.
