The 632E uses a larger main hydraulic pump and valves for faster operation and better multifunctioning. The hydraulic cylinders are larger allowing the machine to run pressures that are 10% lower while increasing performance by 10% on average. Cylinder rod sizes have been increased by 25%.
Load sensing control and a simplified steering circuit lead to more responsive and adjustable steering control. A newly enhanced EHS® transmission produces 11% more torque — with the same top speed as the previous generation of EHS.
The new OB20 rear axle – specially designed for the 632E — provides 47% more torque capacity and nearly twice the life on all bearings. The service brakes and park brake are incorporated into the new axle. The axle mounting has been redesigned to use four high-strength 30 mm (1.18 in) bolts and two 30 mm studs on each side mounted to a massive 77 mm (3 in) thick steel frame. The new design transfers the force to the skidder chassis and can better handle the higher torque load of the new axle and uprated EHS drive. Rear drive shafts have been increased in size to 8.5C from 7C.
Operators will see additional improvements in the cab starting with the automatic, air-ride seat. A new instrument panel layout improves placement of electrical outlets and the electronic control system display. Operators will enjoy finer joystick control of the travel speed. The new high visibility arch means a 10% improvement in visibility to the ground through the arch. LED lights, improved boom light location and a new arch light further enhance visibility to the grapple area.
