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.

Offshore Wireline Unit
The KOLLER Offshore Wireline Unit has been designed for measurements and workover activities with wire capacities above 7,650 m / 25,000 ft. It is suitable for both offshore and onshore applications. The 131 HP guarantees maximum pull force and speed at any depth, even with heavy tools. One of the new features of the power pack is a maintenance free flame trap together with a fault analytic system. The optional available battery startup makes the system independent of any external power supply.
Stand 15-350 non-mag
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 30-200 long
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.
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.

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.
Laydown frame
A perfect tool to ensure safe core samples extraction from the core string on surface. The frame allows to lay down the core samples horizontally without damage, for example directly from the rig floor onto the catwalk. The frame can also be coupled directly to the Core Saw for the core samples to be cut into transportable pieces with protective tube using the saw.
