Overview
The RG 21 T is the most powerful telescopic-leader machine in RTG Rammtechnik's RG range. Built on the BS 65 RS carrier with the hydraulically clamped UW 70 R undercarriage, it delivers 563 kW at 1,800 rpm from a Stage V CAT C18 engine and up to 850 l/min of hydraulic flow. The telescopic mast extends to 26.8 m and retracts to 14.0 m for transport, supporting pile lengths of 21.4 m with a vibrator and above 20 m for CFA, SMW, SCM, SCM-DH and CSM soil-mixing methods. The optional Energy-Efficient Power (EEP) package with Eco Mode cuts fuel consumption by up to 30% and reduces noise significantly. The high-comfort Bauer cab, B-Tronic touchscreen with data acquisition, and B-Drive control system are standard.
