GRUNDOCORE 1500/650

THE VARIABLE ONE

PERFORMANCE FEATURES

Application of crowned bore headswith a max. diameter of 1500 mm
Great cutting depth of 650 mm
Strong torque of 2320 Nm
Crowned bore heads for asphaltand concrete cover layers

The GRUNDOCORE 1500/650 core drill unit complements the keyhole technology with circular walk-in excavation pits of up to 1,500 mm in diameter. Especially with sewer rehabilitation methods, this technique has turned out to be very economical and highly productive. The GRUNDOCORE 1500/650 offers optimal ease of operation and is easy to transport despite the large crowned bore head, due to its compact frame design.

01. Flange for crane connection and forklift reception –very easy transportation
02. Step-less adjustment of the rotational speed and thrust force–the optimal bore parameters are maintained
03. Use of various crowned bore heads possible –diameter range: 800 - 1500 mm
04. Crowned bore head guide – stabilisation of the crowned bore head for spot drilling
05. 3 hydraulic vertically adjustable pedestals (300 mm) – simple alignment of the core drill unit
06. Wireless remote control – control of the drilling process from an optimal and safe position
07. Output signal for activation of external flushing pump – adapt flushing volume to drilling process
08. Non-wearing rotary transmission – minimal maintenance effort
09. Easy to dismantle panelling – safety shutdown for maximum safety at work
