Overview: The document provides detailed specifications and features of the APAFOR® 220 geotechnical drilling rig, designed for challenging site access with a track-mounted system. It highlights the rig's compactness, transportability, and versatility in various drilling methods.

General Specifications: The rig features a mechanically welded steel frame mounted on a variable width rubber track, adjustable from 720 to 1060 mm. It includes three emergency stops, a safety wire, and remote control capabilities, either wired or wireless.

Technical Specifications: The APAFOR® 220 is powered by a 26 HP soundproofed Caterpillar diesel engine. It offers a maximum torque of 100 daNm at 100 rpm, with a rotation speed ranging from 0 to 100 rpm. The rotary head translation speed is 22 m/min, and it has a pull-up force of 1,600 daN. The rig is equipped with proportional hydraulic controls, four mechanical or hydraulic stabilisation feet, and auger guides for diameters of 140 mm and 63 mm. Mast lengths are available in 1.95 m, 2.45 m, or 2.75 m. The basic model weighs 1,100 kg and measures 2.4 m in length, 1.3 m in width, and 2.9 m in height in drilling position.

Options: Available options include a hydraulic rod clamp with a 40 kN force, a thermal engine injection pump for rotary injection drilling, a separate drilling mast and control panel for indoor or confined space work, and fittings for heavy dynamic penetrometers (DPSH, SPT) and hammering works. Additional options such as a percussion hammer and prefitting for a drilling data logger are also available upon request.
