Pile-driving arm manufacturers: characteristics of pile-driving armMore
1. The pile-driving arm is fully hydraulically driven and can be rotated 180 degrees left and right, and the operation is simple;
2. It is convenient to transport and can be integrated with the excavator;
3. The piling arm can be applied to various work sites, and can also be used in riverside, water surface, and underwater operations on rainy days;
4. Steel piles, cement piles, steel rail columns, iron plates, H plates, and drainage belts that can be driven and moved;
5. Pile-driving arm manufacturers: using German original hydraulic motor drive (rotating motor and vibration motor), small size, light weight, but can output high power and high speed, high reliability, sturdy and durable;
6. The advanced oil circuit design enables the jamming and vibration to be carried out simultaneously, which improves the efficiency of driving and piling, and better protects the main oil system of the excavator. The newly designed safety device makes the chuck the safety device when the vibration operation occurs. Automatic tightening, no loosening of the pile board, high stability and efficiency;
7. The pile-driving arm adopts cylindrical stick bearings imported from Japan, which has low noise, high speed and high reliability, and the quality of the whole machine is better;
8. When driving and pulling piles, the speed and vibration frequency can be adjusted to meet the requirements of different working environments;
9. Optimize the design of the device to protect the two ends of the pile against damage, and work in close proximity to the building will not damage the building itself;
10. The pile-driving arm adopts well-known brand shock absorbers to reduce vibration and noise, which is more in line with environmental protection requirements and improves the long-term reliability of the machine.
Pile-driving arm manufacturers: For underwater operations, an additional exhaust pipe is required.
Steel sheet pile machine manufacturers: What are the misunderstandings of pile driver maintenance?2021-04-22
Steel sheet pile machine manufacturers: introduction to the maintenance misunderstandings of pile driversMore
Misunderstanding 1: Improper starting method of pile driver
The serious consequences that a 360° rotating pile driver can cause: serious damage to the machine.
In winter, some drivers often start the diesel engine without water (start first, then add cooling water) to start the diesel engine abnormally. This practice can cause serious damage to the machine, and its use should be prohibited. The correct preheating method is: first cover the heat preservation quilt on the water tank, open the drain valve, and continuously pour 60-70℃ clean and soft water into the water tank, and then close the drain valve when you touch the water flowing out of the drain valve with your hands and feel hot. Fill the water tank with clean and soft water at 90-100°C, and shake the crankshaft so that all moving parts are properly pre-lubricated before starting.
Misunderstanding 2: Low temperature load operation of pile driver
The serious consequences that can be triggered: cause serious wear and tear of the machine.
Steel sheet pile machine manufacturers: After the diesel engine started to catch fire, some drivers couldn't wait to put into load work immediately. Diesel engines that catch fire soon, due to the low body temperature and high oil viscosity, the oil is not easy to fill the friction surface of the moving pair, which will cause serious machine wear. In addition, plunger springs, valve springs and injector springs are also prone to breakage due to "cold brittleness". Therefore, after the diesel engine starts to catch fire in winter, it should be idling for a few minutes at low and medium speed, and then put into load operation when the cooling water temperature reaches 60°C.
Misunderstanding 3: Do not pay attention to the heat preservation of the pile driver
Serious consequences that can be triggered: reduced working life and damage to the engine.
Steel sheet pile machine manufacturers: The low temperature in winter can easily cause excessive cooling of the equipment during operation. Therefore, heat preservation is the key to good use of the machine in winter. In the northern regions, all machines used in winter should be equipped with cold-proof equipment such as insulation sleeves and insulation curtains. In addition, the thermostat plays an important role in increasing the temperature of the pile driver. Therefore, check whether the thermostat is working properly before entering the winter, and replace the failed thermostat in time.
Steel sheet pile machine manufacturers: introduction to the piling steps and electricity issues of the pile driver2021-04-09
Steel sheet pile driver manufacturers: The common pile drivers on the market are mainly based on mechanical power, which are usually divided into hammering method, oscillation method and static pile pressing method; after the pile driver enters the construction site, it will be based on the site's topographical conditions and the condition of the foundation soil. Factors such as the placement of the piles, the length of the piles and the ease of movement of the pile frame determine the sequence of pile driving, so that the depth of the piles is basically the same, and the foundation soil is evenly compacted.More
If there are not many piles, the pile driver should start from the center and move in opposite directions from the two ends. However, when the pile foundation area is large, the pile foundation should be divided into several sections and then carried out separately within the range of each section; hydraulic pile drivers should prevent From the outside to the inside, or from the periphery to the center, prevent the foundation soil in the middle of the pile foundation from being compacted, and increase the difficulty of driving. Even if the driving is forced, the driven neighboring piles will rise up; in the clay area, It is also necessary to prevent it from being carried out in one direction, causing the soil to knead to one side, forming piles into the soil with different depths, uneven soil density, and uneven settlement of the entire pile foundation in the future; if the pile distance is greater than or equal to 4 times In the case of pile diameter or side length, the impact of the piling sequence is smaller, but if it is an area group pile, the piling sequence must be planned in advance to prevent adverse consequences or safety accidents.
Steel sheet pile machine manufacturers: Which operations of the pile driver are incorrect?2021-03-25
Steel sheet pile machine manufacturers: Abrasion and failure during the construction of pile drivers are normal. If the operator performs incorrect operations on the equipment, it will also affect its use, accelerate the wear of parts, and shorten the service life.More
