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.
2-split Offshore Wireline Unit
The KOLLER 2-Split Offshore Wireline Unit has been designed for measurements, slickline and e-line 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.
3-split Offshore Wireline Unit
The KOLLER 3-split Offshore Wireline Unit has been designed for measurements and workover activities with wire capacities above 7,650 m / 25,000 ft. The 3-skid layout is separated in a winch, an operators and a hydraulic power pack container. The hydraulic pump / motor combination guarantees high pull force and speed at any depth.
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.
Bucking Unit 40,000 Nm

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.
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
Double Support Table
KOLLER support tables are made for lay down and work on downhole tools or other cylindrical parts in an ergonomically working position. Since the workpiece is placed on rollers, it can be easily turned to the right position. For lock it in position, the rollers are arrestable. In the single version, the distance between the roller consoles is adjustable. The tables are equipped with a stable elevated tray for tooling equipment, parts or measuring devices. A circumferential edge prevents roll down of parts or drip down of liquids to the workplace.
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.
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.
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.
