The CH 300 is the smallest model of the CH range. It has a transport weight of 30 tons with the rotary head and Kelly bar installed. The rig is fully self-erecting: once on site, it can be off loaded from the truck and set up without the need for crane with the help of automated rig-up systems. The lateral extensions of the undercarriage allow for reduced dimensions during transport and ensure, when opened, a good stability of the machine during operation.

The design of the CH 300 incorporates a number of features aimed to enhance efficiency and cost-effectiveness: this unit is the first one of the CH range equipped with an innovative high efficiency hydraulic system that significantly reduces fuel consumption. It is designed to meet the highest standards of environmental sustainability, both at European and North American levels (Stage V / Tier 4 Final).

Despite the lightweight design, the CH 300 offers a high torque output, allowing to undertake drilling tasks that would normally require the use of larger and heavier equipment. The rig can be configured both for uncased bored piles (excavated by dry method or stabilized by fluid overpressure) and cased piles (where the casing installation is carried out by rotary drive), up to a maximum depth of 48.5 m (159 ft). The CH 300 can be easily converted to perform CFA drilling with augers of 1,000 mm maximum diameter and a maximum depth of 19 m (62 ft).
