ZYB420K-B Jack in piling machine

Fast piling speed Excellent piling quality No limitation on pile length No noise No vibrations

Structure and function: clamping and piling mechanism, lifting mechanism, hoisting mechanism, hydraulic system, electric system, etc, with the functions of hoisting, pressing, walking and steeringApplication Scope: 1) . No limitation on pile length. suitable to work under various geological conditions, such as collapsible loess, silty clay, sand bed, sedimentation geological stratification and fill stratum and so on.2) . No noise, No pollution during construction, especially suitable for operations in areas with noise control such as schools, social communities, and urban areas.3) . No vibrations. Suitable for vibration-control areas such as subways, overpass, dangerous buildings, precision instrument buildings and those nearby banks.
