Elevating Head and Tailstock
20,000 lb Capacity

The Red-D-Arc RDA EHTS200 NA consists of an elevating headstock and tailstock assembly each with two vertical columns and machined slideways connected by fabricated tie frames offering a combined capacity of 20,000 lb
The elevation drive is via an AC geared motor reduction worm gear actuator, re-circulating ball screw and nut. The machine is fitted with a control station mounted on the side of the headstock frame and fitted with an isolating switch, emergency stop, elevation (raise/lower) and rotation (clockwise/anti-clockwise) controls.

Supported between the two vertical columns of both the headstock and tailstock assemblies are fabricated steel carriages, which run on 12 anti-friction rollers, 6 of which are adjustable to ensure minimum “free play”. The rotation drive is housed inside the headstock assembly carriage and consists of a worm reduction gearbox driven by a single speed AC motor with timing belt and pulleys. The final drive is straight spur gear pinion onto an internal gearing-slewing ring, supporting the faceplate.
