Price estimate
We do not have a price for the Durma AD-Servo 40400 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
At 400 ton, the Durma AD-Servo 40400 moves the hybrid series onto its heavy frame. Bending length is 4,050 mm (159.4 in), and several dimensions change compared with the AD-Servo 40320 of the same length.
The throat deepens to 510 mm (20.1 in). The table rises to 1,050 mm (41.3 in). The columns move closer, to 3,400 mm (133.9 in) apart, because the side frames are thicker. And the standard back gauge X travel becomes 750 mm (29.5 in), with 1,000 mm (39.4 in) still optional. A buyer comparing drawings should expect a different machine, not a stronger copy.
It weighs 27,780 kg (61,243 lb), is 2,110 mm (83.1 in) wide and 3,450 mm (135.8 in) high. Foundation, lifting and transport planning start from those figures.
Speeds are 150 mm/sec in rapid and return and 9 mm/sec in work. Stroke is 365 mm (14.4 in) and daylight 630 mm (24.8 in). The servo pump drive is rated 11 x 2 kW with 80 x 2 L of oil, the same as on the AD-Servo 40320, which is unusual for a machine of this force and is the point of the hybrid design: the motors deliver power only during the stroke. The table is 154 mm (6.1 in) narrow or 300 mm (11.8 in) wide, and the R axis of the back gauge works at 350 mm/sec over 250 mm (9.8 in).
