Detailed Product Description

Used for drilling large blast hole. It is especially convenient to be used during the initial period of opencast working, other drill carriage unable to reach, unable to carry on the normal work.

Drive power of drill: Hydraulic motor
Max. pushing power (N) : 4500

Q: Gasoline rammer return pipe leakage is going on: This problem is not recommended to repair and repair, repair and repair once hundreds to thousands or even tens of thousands. But it may not solve the problem, but also hurt the car. It is recommended that the majority of car owners use the "free repair and repair" method to solve the problem of automobile oil leakage.

Q: Should the foundation be compacted by tamping machine?: Yes, but should meet the design requirements of compaction requirements

Q: Flat vibration tamping machine, ramming function for slope tamping machine? What is the most suitable?: Because Cromwell, STANLEY products, agents and materials supply service providers.I hope you can find the answer.

Q: What are some of the electric ramming machine accessories?: The main parts of lifting machine, electric basket safety lock, suspension platform, suspension structure, distribution box, steel wire rope, the other consists of Rieter electric basket accessories such as; motor end cover, AC contactor, transformer, switch, fuse, insurance, oil seal frame, leakage circuit breakers, plug, signal lamp,

Q: The advantages and disadvantages of gasoline and electric rammer breaststroke tamping rammer: Domestic gasoline flat rammer just so so, domestic gasoline shock ramming no one qualified!The only advantage of an electric RAM - cheap! Nothing else

Q: How to connect the power line ramming machine: If you want to know more, you can go to "power business" or "China Power Grid" and other industry portal authoritative website!

Q: Gasoline is what reason no vibration rammer: If the gasoline engine is working properly, the tamper does not vibrate. First, check that the oil is still there. (there is an oil drain under the retractable spring rubber).

Q: How to remove the 90 electricity tamping machine: When the pressure tamping machine on the ground zero, the ramming machine as the research object, the ball on the flywheel F=Mg... 1.And with the ball as the research object, the flywheel on its F and Mg gravity force under the action of uniform circular motion, F '02 +mg=mL... 2According to Newton's third law: 'F=F'

Q: CFG pile base can use tamper tamp it: 2. Basic principles:The cohesive strength pile is the representative of composite foundation, and is used in high-rise buildings and super high-rise buildings. CFG pile is the abbreviation of cement fly ash gravel pile (cement, fIying-ash, gravel, pile). It is made of cement, fly ash, gravel and sand with water of high bond strength pile formed by mixing together, to form a composite foundation and pile and cushion. CFG pile composite foundation cushion and connected by the foundation, whether pile general fell hard soil or soil, can ensure the soil between piles has always been involved in work. Because the strength and modulus of the pile is larger than the soil between the piles, the stress at the top of the pile is greater than that on the soil under the action of the load. The pile can transfer the load to the deeper soil layer and reduce the load that the soil between the piles bear. Thus, because of the action of the pile, the bearing capacity of the composite foundation is increased, the deformation is reduced, and the CFG pile is not suitable for reinforcing bars, and the industrial waste material and the fly ash are used as admixture, thereby greatly reducing the project cost.The design of composite foundation, cushion thickness is arranged between the base and the pile and soil is composed of loose granular material, is a core technology of composite foundation. The foundation is set cushion, a great impact on the bearing capacity of composite foundation. If there are no cushion, loading behavior of the composite foundation and pile foundation is similar to that of soil between piles bearing capacity of composite foundation can be difficult to play. Under the foundation of cushion, settlement of bearing capacity of soil between piles play not only depends on the pile, the pile end even fell on good soil, but also to ensure the load to the soil between piles with cushion layer, the soil pile to bear load.

Q: Three-phase electric rammer or two-phase power: Another difference is that the power used is different. Usually the home and no three-phase power supply using single-phase motor, power is usually relatively small, industrial and high-power places are selected three-phase motor.
