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.

Slickline Alu Unit
The KOLLER Slickline Alu Unit has been designed for workover activities with special weight restrictions.
The 2-skid layout is separated in a winch / operators module and a hydraulic power pack. The hydraulic pump / motor combination guarantees high pull force and speed at any depth. The unit starts with a spring-starter which makes the system independent of any external power supply.
The modular system is very flexible enabling a set up with or without cabin. Not using the cabin, more or larger wire can be spooled before the weight restrictions will be executed.

Stand 50-350 / 30-200 see specifications
Stands are used for cranless assembly, disassembly and storing of downhole tools or other cylindric parts. For different tool diameters, the distance between the support rollers is adjustable. To allow working in an ergonomic position, the height of the stands can be adjusted. Except type 15-350 non-mag, all stands are fitted with transport rollers for move them without load.
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.
Washing Plant L-700
The KOLLER Washing Plant L700 is used for degreasing and cleaning of parts or tools. Two programs are available, automatic and manual. For manual cleaning by hand brush the washing table will be lifted to an ergonomic working height. The KOLLER Washing Plant L700 is especially designed environmentally friendly. During the cleaning process the fluid is continuously circulated, filtered and at the end oxygenated with a separate oxygen pump. Therefore its liftime is very long.
Bucking Unit 18,500 Nm
The bucking unit have been designed to make and break screwed connections with high torques. The unit is a combination of a KOLLER hydraulic vice 220 kN and a hydraulic operated chain tong. For the basic unit without electronic data logger, no electrical supply is required. Both, the hydraulic vice and the tong are supplied by pressure air driven hydraulic power packs. Since the bucking unit is mounted on a solid steel frame with forklift truck pockets, it is transport friendly and can be moved easily on site.
Stand 10-350 non-mag
