It provides a maximum working height of 44.44 m and a maximum platform height of 42.44 m, with a maximum operating range of 25.60 m (+0.6 m) and a maximum platform range of 25.00 m. The machine is powered by a Deutz TD2.9 L4 diesel engine rated at 55.4 kW. Developed by TEUPEN, DINGLI’s German R&D center, the BT44RT uses a modular design horizontally and vertically, with 85% of components common across the full range. Electric, diesel and hybrid models are developed on the same platform. The patented one-key in-situ axle expansion, combined with four-wheel drive and steering, allows the axle to expand and retract in narrow spaces as required. A 230° jib amplitude allows the jib to be hooked back to suit standard container transport. ## Key Features - Developed by TEUPEN, DINGLI’s German R&D center - Modular design horizontally and vertically, with 85% of components common in the full range; electric, diesel and hybrid models developed on the same platform - Patented one-key in-situ axle expansion, four-wheel drive and steering, with axle expansion and retraction in narrow space at will - 40% increase in action efficiency compared with equivalent products in the industry - Cat3 safety architecture with full redundancy of electronic control software and hardware - Jib with 230° amplitude, which can be hooked back to suit standard container transport - Equipped with a 55.4 kW high-power engine, gradeability up to 45% ## Applications The BT44RT diesel articulating boom lift is suited to high-reach work at height where a large operating range and rough-terrain mobility are required. Typical application scenarios include high-rise construction, industrial maintenance, steel structure installation, exterior facade work and other site operations that need a 44 m class articulating boom lift with four-wheel drive and steering. ## Technical Specifications | Category | Parameter | Value | | --- | --- | --- | | Dimension | Max.
