China Brand New Sunward SWTM1880B Crawler Crane Dynamic Tamping Machine for Sale
1. The dedicated walking-type chassis walking mechanism has a large grounding area and a small grounding specific pressure, which can effectively prevent the machine from sinking and tipping, ensuring the stability of the whole machine.
2. The combination of the vertical truss and the rigid oblique support structure greatly increases the lifting height of the rammer, with strong tamping capacity, high strength and high rigidity, which effectively guarantees the stability of the whole machine.
3. The unique vertical structure of the herringbone truss is easy to use, and can be self-supported without the aid of a crane, saving installation costs. .
4. Remote control technology can not only observe the construction from a long distance, but also fully guarantee the safety of the construction personnel
5. The hoisting winch uses a unique large-displacement winch motor, which is more stable in operation. The controlled automatic drop hammer device greatly improves the lowering speed of the empty hook and effectively improves the work efficiency.
6. Using high-power motor and matching electrical control system, compared with diesel engines, the use cost is low, the noise is small, and there is no vibration.
7. The four-leg hydraulic cylinder is adjustable to ensure the verticality of the pestle holder.
Dynamic soil compaction
For impact compaction a heavy tamper weight is dropped from heights of up to 40 metres onto the ground to be compacted. This dynamic input of energy increases the density of the building ground. The craters created through impact compaction are refilled with suitable material and further compacted, if necessary. Duty cycle crawler cranes of the HS series carry out the compaction process efficiently and automatically with free-fall winches and crane control.
Procedure for dynamic compaction
1. Positioning of the drop weight over the compaction point
2. Lifting the drop weight to the drop height
3. Free fall of the drop weight onto the compaction point
4. Lifting the drop weight for the next blow
5. Filling the compaction crater and grading the area
