• High engine output with automatic engine speed
control
• Controlled entirely from cab
• Sturdy and solid rig design
• Solid parallel kinematics on the basic machine
• High pull and push forces
• High torque
• Completely self-rigging (no auxiliary machines
required)
• Large range of working tools (all common drilling
works can be performed)
• Stepless leader inclination 5° forward - 15° backward
depending on type of equipment
• Automatic vertical alignment
• High alignment forces
• Simultaneous control of several movements via
Load-sensing multi-circuit hydraulics
• Quick change of rotaries possible through quick
connection
• Equipment design according to latest European
regulations and standards
• All components designed to fulfill the requirements
of a drilling rig
• High manufacturing quality through quality control by
the PDE-system
