AVK Group, LLC. is dealing with exporting, shipping drilling rigs, as well as provides training of personnel and maintenance services.
Additionally we provide drilling tools for your machinery for any types of work.
JVR series of rotary drilling rigs from the CHTC JOVE is a wonderfully designed machinery with reliable structure, high power and extendable chassis, essential for work on rough ground.
Crawler base is stable and mobile, perfect for work in narrow areas. JVR series are affordable, efficient, environmentally friendly and reliable.
CAT EFI engine is boasting high power and torque parameters. Power is fed directly into the turbocharged diesel with intercooling combined with CHTC electrical system. Drilling rig from CHTC JOVE allows you to save up to 10% of consumed fuel, compared to other similar models in similar conditions.
Main and auxiliary hydraulic systems are providing optimal distribution of hydraulic flow and load sensitivity, depending on a type of work. These functions are useful for improving efficiency of the working process.
Key elements of the electric system are produced by the German and Finnish manufacturers. Operator can adjust the working parameters of the engine, pump and main valve from his cabin. Highly sensitive sensors are providing precise measurements of current parameters, as well as an analysis of the working process.
