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.

Bump cutter RSG 1750

Bump cutters are mobile grinding machines for the treatment of surfaces made of concrete or asphalt. A grinding shaft, equipped with diamond saw blades and distance plates removes material in a grinding process. The working width depends on the used machine type and on the number and types of diamond saw blades. For make different surface patterns, the grinding shaft can be equipped with various combinations of blades and distance plates. In general, 3 methods are distinguished – grinding, grooving and bump cutting.

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

Customized Solutions

Focusing on our core competence mechanical engineering, we have successfully planed, assembled and created a variety of customized solutions over the years. Supporting clients with started projects has also been part of our portfolio.

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.

Floor Saw RSF 820

The all-rounder for various floor sawing jobs The RSF 820 can be equipped with various mounting kits and allows the user to perform multiple cutting or grinding applications with only one basic machine. Our engineers were able to draw on 40 years of experience in the development of this fully hydraulic floor sawing system. In addition to the existing expertise, special wishes and requirements of our customers were also incorporated. The RSF 820 is particularly flexible in the configuration and positioning of the operator station. Various attachment points allow mounting on all sides of the machine. Operation and monitoring are carried out intuitively via a keypad and a joystick.

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.

Joint Brushing Machine RSB 120

The rotating brush (rotates in reverse direction), raises loose material from inside of the joint, such as slurry or small stones, to the front. The result is a largely dust-free joint, which forms the basis for the durability of the sealing compound to be poured into the joint in the next step.

The RSB 120 is equipped with a two-stage air filter which effectively prevents the penetration of dust into the motor. The filter cartridge can be replaced without tools.
