536-6580 Swing Motor Group for Caterpillar equipment. A swing motor is a crucial hydraulic component in heavy equipment, primarily excavators. Its job is to rotate (or "swing") the entire upper structure of the machine—the cab, boom, arm, and attachment—360 degrees on its undercarriage.

The 536-6580 Motor GP is not just the internal motor; it's a complete group or assembly that typically includes:

  • The hydraulic motor itself

  • The reduction gearbox (swing drive)

  • The parking brake

  • Possibly the swing circle gear (pinion)

 

The KR250CS Low Headroom Hydraulic Piling Rig is a high-performance rotary drilling machine specifically engineered for construction in space-constrained environments, such as beneath bridges, inside industrial buildings, or in subway and basement projects.

Combining powerful torque output with a compact structure, the KR250CS overcomes the limitations of conventional rigs in low-clearance conditions, making it the ideal solution for urban foundation engineering. Its modular design, robust construction, and intelligent control system ensure maximum drilling efficiency and operational flexibility.

This set of cutter wheels is suitable for a wide range of ground conditions and effectively prevents clogging in clay layers. Additionally, it extends the service life of the wheels when working in hard rock formations.
Pipe jacking machines use shield technology to excavate soil or rock with a rotating cutter head, removing the excavated material via a mud conveying system while hydraulic jacks push precast pipes into the tunnel and grout stabilizes the walls.​ These machines are applied in diverse municipal and civil projects, including building underground water supply/drainage systems, installing gas pipelines, optical cables, and constructing subway tunnels, minimizing surface disruption.​ Regarding types, the slurry balance machine suits various soil and high - groundwater conditions; the Earth Pressure Balance Machine is for soft to medium - hard soils; and the rock machine, equipped with powerful tools, is for rock formations and even mixed soil - rock conditions. They are key to modern underground construction.
