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.
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.

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.
Trolley 30-200 short
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.
Workbench 2000
The Koller workbenches have been designed to make and break screwed connections with high torques. To accommodate the high torsional forces, the workbenches have extremely stable and torsionally rigid frames. All available workbench equipment is equipped with dovetail mounting plates and are stepless slidable and positionable as well as turnable for 180 degrees in the bench.
