Microtrenching is a minimal-destructive and very fast method of laying communication cables in existing traffic areas. In the process, wide joints are cut into the surfaces with diamond blades. Directly after the cut, ductworks are inserted and then the joint is potted. Time and cost-intensive earthworks at the edge of the traffic areas are thus avoided or minimized.

Lightweight Wireline Unit
The KOLLER Lightweight Wireline Unit has been designed for workover activities with wire capacities above 7,650 m / 25,000 ft. The 2-skid layout is separated in a winch / operators container and a hydraulic power pack. The hydraulic pump / motor combination guarantees high pull force and speed at any depth. The startup by spring starter makes the system independent of any external power supply.

Trolley 50-200 long / 50-200 see specifications
Trolleys are used for cranless assembly, disassembly and transport of downhole tools or other cylindric parts. For different tool diameters, the distance between the support rollers is adjustable and for different tool lengths, the center bar is stepless extendable. To allow working in an ergonomic position, the height of the trolley can be adjusted. Each trolley is grounded and can be used in ESD (electrostatic discharge) environments out of the box. A turnable tray for tooling equipment is optional available.
Hydro Vice 220 kN
The hydraulic vice have been designed for short-term clamping of downhole tools or other cylindrical workpieces. The 3-point clamping is carried out via a manual spindle and a hydraulically operated prism. The spindle is turned down to the diameter of the workpiece. Then the required clamping force is generated by the hydraulic lifting of the prism. The prism is equipped with specially textured jaws that effectively prevent the workpiece from rotating.
Core Saw
The Koller Core Saw is used to cut the inner tube with drill core into 900 – 1000 mm sections. The conical drums of the connected lay down frame feeds the inner tube to the saw, where an air-powered diamond or corundum saw blade cuts it into the sections described above. The inner tubes can be made of aluminum alloy, fibreglass or heat-treatable steel. In most cases, aluminum tubes are used, so the equipment is optimised to effectively cut filled-core aluminium tubes. The core saw is suitable for offshore and onshore applications
