   In excavation operations, the bucket teeth are the most heavily loaded components and are consumable parts. Especially in stone excavation work, the bucket teeth wear out very quickly. The condition of the bucket teeth directly affects the working efficiency of the excavator. Some incorrect operations will accelerate the wear and fracture of the bucket teeth. Today I will share with you some precautions when using the bucket for your reference. In excavation operations, the bucket teeth are the most heavily loaded components and are consumable parts. Especially in stone excavation work, the bucket teeth wear out very quickly. The condition of the bucket teeth directly affects the working efficiency of the excavator. Some incorrect operations will accelerate the wear and fracture of the bucket teeth. Today I will share with you some precautions when using the bucket for your reference. 1 things to note    Try not to retract the bucket when lifting the boom. If you retract the bucket, the bucket teeth will be subject to upward traction and damage the bucket teeth. When the big arm is lowered and the forearm is raised outward with too much force, the bucket will hit the stone, which may easily damage the bucket teeth and even the forearm.    The bucket teeth should be perpendicular to the working surface when digging, or the camber angle should be less than 120 degrees to prevent the bucket teeth from breaking due to excessive inclination.      Do not use the collision force of the bucket side wall to move objects or the rotation force to move large objects. When the bucket collides with the rock, the bucket, arm and working device will generate a large load, seriously affecting the service life of the excavator.    Use the big arm or small arm to drive the bucket, and quickly drop it to impact the excavation, especially if it acts on hard rocks. The huge impact force will react on the entire working device and pin of the excavator. It may cause a certain amount of wear and tear, and in severe cases, the working arm may crack or break.    Try to avoid direct contact with objects on the back of the bucket, and cooperate with the forearm retrieval action when digging hard objects.    During construction, if there are large objects such as earth or stones in front of you, do not push the stones aside with a rotational movement. If things go on like this, the side blades, forearm and swing motor drive teeth will be damaged.    Do not frequently use the traveling motor to drive the bucket. Doing so will cause the bucket and bucket teeth to wear due to the huge external force exerted by the traveling motor. 2 Daily inspection of bucket    Check the bucket for wear and cracks. If the wear is severe, reinforcement should be considered. If there are cracks in the bucket, they should be welded and repaired in time to avoid increasing the length of the cracks due to delayed repairs.    You can kick the bucket teeth with your feet to check whether the bucket teeth are stable. If they are loose, tighten them immediately.

Excavator extension arms are versatile and powerful machines used for a variety of construction and excavation projects. The extension arm is an important part of the excavator, allowing the operator to extend its reach and efficiently handle tasks that require extended reach. To ensure optimal performance, regular maintenance on your excavator extension boom is essential. In this article, we’ll outline important routine maintenance tips that will help maximize the life and efficiency of your excavator extension boom. Excavator extension arm maintenance tips are as follows:   1. Visual inspection: Visual inspection of the excavator extension arm before each use is a key step in daily maintenance. Check the boom carefully for any signs of wear, cracks or damage. Look for loose or missing bolts, hydraulic leaks, or any anomalies that may affect the structural integrity of the boom. By identifying and fixing problems early, you can prevent potential breakdowns and costly repairs.   2. Lubrication: Proper lubrication is critical to keeping your excavator extension arm running smoothly. Regularly lubricate all moving parts of the boom, such as joints, pins, and bushings. Be sure to use the recommended lubricant and follow the manufacturer's guidelines for lubrication frequency and quantity. Adequate lubrication reduces friction, minimizes wear, and extends the life of the extension arm.   3. Hydraulic system maintenance: The hydraulic system plays a vital role in the operation of the excavator extension arm. Routine maintenance of hydraulic systems is necessary to ensure optimal performance. Check the hydraulic fluid level and inspect the system for any leaks or damaged hoses. If necessary, top up the hydraulic oil and address any leaks or defects promptly to prevent potential failure.   4. Cleaning: Cleaning your excavator extension arm regularly will help remove dirt, debris, and corrosive substances that can cause damage over time. Use a pressure washer or hose to clean the spray boom thoroughly after each use. Pay close attention to areas like seams and gaps where buildup is more likely to occur. Be careful not to spray high-pressure water directly onto sensitive parts, such as electrical connections or hydraulic seals, to avoid damage.   5. Boom Alignment: Proper boom alignment is critical for smooth operation and efficient digging. Routine inspections should be performed to ensure that the boom is properly aligned. Use the excavator's control system to verify that the boom is running in a straight line without any noticeable deviation. If necessary, adjust alignment according to manufacturer's guidelines. A misaligned boom can put excessive stress on components, leading to premature wear and potential failure.   6. Grease and Tension Track System: The track system is another important component of the excavator. Lubricate tracks regularly to prevent corrosion and maintain smooth movement. Check track tension and adjust if necessary to ensure it meets manufacturer's specifications. Properly tensioned tracks increase stability, reduce chassis wear, and provide better control of the movement of the extended boom boom.   7. Check wearing parts: Wear parts, such as bucket teeth, cutting edges and buckets, play an important role in the efficiency of the excavator. Check these parts regularly for signs of wear and replace if necessary. Worn consumables can lead to reduced productivity, increased fuel consumption and additional stress on the excavator extension arm.

   Amphibious excavators are referred to as amphibious excavators and are also called wetland excavators. The amphibious excavator is a very unique machine. It can enter areas that conventional equipment cannot enter. It is very suitable for working on river banks and wetlands, and can handle various challenging working conditions. Amphibious excavator at work      The traveling device of the amphibious excavator adopts a catamaran-type pontoon structure track frame and sealed box-shaped track shoes to ensure safe cruising on the water. Due to the height limit of the floating box of the amphibious excavator, construction can be carried out in water depths of no more than two meters. If the water is too deep, the amphibious excavator will float on the water and the bucket will not work.      Amphibious excavators are divided into pontoon type and pontoon type according to different structures. The pontoon type uses the chain rails of the original vehicle to lengthen and then hang an external pontoon beside the traveling support. This type of construction is relatively low-cost but the chassis is not sealed and will be severely corroded after long-term use. Later maintenance costs a lot of money, as well as supporting wheels and chain rails. Increased wear and tear. Amphibious excavator with external floating tank      The substructure of the amphibious excavator has a low grounding ratio and can walk and work in shallow water areas. Due to the large volume of its buoyancy tank, it can generate great buoyancy in the water. Amphibious excavators are particularly suitable for driving and operating in soft, muddy areas, tidal flats, and swamps. They are widely and efficiently used in water conservancy projects, the dredging of rivers and lakes in urban and rural construction, and the resource development and environment of wetlands, swamps, and tidal flats. For remediation and excavation operations, this cannot be compared and replaced by general excavators. Amphibious excavator   The main purpose:   1. Swamp land management, low-yield fields, saline-alkali land transformation, and urban diversion and water supply projects.   2. Coastal beach management and reclamation projects.   3. Well location engineering in shallow sea oil and gas fields.   4. Excavation, dredging, slope repair, embankment construction, and drainage pipeline erection during dredging.   5. Projects such as embankment construction, piling, development and cleaning of fish ponds and shrimp ponds during flood control and rescue operations.      Maintenance of amphibious excavators mainly focuses on the hydraulic and engine parts. The engine is equivalent to the heart of the amphibious excavator. Maintaining the engine of the amphibious excavator is equivalent to ensuring the performance and service life of the amphibious excavator.    70% of many amphibious excavator engine failures are actually caused by improper maintenance and improper operation. Here are some common sense tips for amphibious excavator engine maintenance:   1. "Maintenance instead of repair".   2. Strengthen the cleaning and maintenance of the oil filter, crankshaft ventilation device and ventilation device, and replace the filter element in time according to the instructions.   3. The oil filter should be cleaned regularly. When cleaning, check whether the oil leaks out of the float head. If so, drill a small hole next to the float to drain the oil, and then seal and weld it. Otherwise, oil will leak into the float head, and the filter will sink to the bottom of the oil pan. The deposited dirt will be sucked up and block the filter screen and oil passage.   4. Control the temperature of the engine during normal operation to prevent the radiator from "boiling". It is strictly forbidden to drive without adding cooling water.   5. Inspect and adjust the technical condition of the crankshaft and bearings promptly. Always unscrew the drain plug on the filter housing to drain out the dirt.   6. For a coarse filter with a rotating handle, the handle should be rotated frequently to remove dirt on the filter disc. To clean the filter, you should disassemble it and wash it thoroughly. Some fine filter elements need to be replaced regularly. If the centrifugal fine filter is working properly, when the engine rotates at low speed, the hum of the rotor can be heard next to it. If you can't hear it, it means that the rotor has been stuck. The main reason is that there is too much dirt and it should be cleaned thoroughly.   7. The air filter is clogged. The engine's air intake system mainly consists of two parts: the air filter and the intake duct. According to different usage conditions, the air filter element must be cleaned regularly. The methods that can be used include high-pressure air blowing from the inside out to blow out the dust in the filter element. Since the air filter element is made of paper, be careful not to make the air pressure too high when blowing to avoid damaging the filter element.   8. Rust and scaling of the engine water tank are the most common problems. Rust and scale will restrict the flow of coolant in the cooling system, reduce the heat dissipation effect, cause the engine to overheat, and even cause engine damage. The oxidation of the coolant will also form acidic substances, which will corrode the metal parts in the water tank, causing damage and leakage of the water tank. Regularly use a powerful and efficient water tank cleaning agent to clean the water tank to remove rust and scale. This will not only ensure the normal operation of the engine, but also extend the overall life of the water tank and engine.   References: [Tiejia Engineering Machinery Network]
