The frame design optimizes visibility. |
Xtreme's design is driven by three key philosophies: visibility, durability, and accessibility. Visibility elements include doing away with visual obstructions at the rear of the machine by optimizing the frame design and deliberate component placement. Toward the front of the machine, the pivot-mounted, heavy duty outriggers are placed for maximum fork visibility. A high-visibility boom angle indicator is also included in the design.
On the durability front, the XRM 1254's hydraulic oil runs through a three-stage filtration system, which includes a suction strainer, followed by a 10-micron high-pressure filter, and lastly, a 10-micron low-pressure filter on its return to the all-steel hydraulic tank. The heavy duty, three-section boom rides on durable melonited rollers, which incorporate sealed bearings that ride on melonited shafts. All pivot points are sealed and use melonited pins and either spherical ball bearings or high-compression bronze bushings. With its damage-resistant induction hardened shaft, the carriage tilt cylinder is mounted on the top side of the horsehead. The dash and all safety decals are made from self adhesive Lexan, and the labels are printed on the back side so they are totally protected.

The XRM 1254 utilizes an innovative aluminum radiator with three replaceable sections, and engine water, transmission oil, and engine charge air are all cooled by the radiator. The engine is mounted directly to a Carraro TLB2 power shift transmission and fueled by a 72-gallon all-steel fuel tank. The hydraulic flow is provided by a proven
Accessing the XRM 1254's service points is easy, as the majority are mounted on the same side of the engine. An electric fuel pump will self-prime the injectors if the unit runs dry. The engine and all hydraulic components are in-frame and shielded by Kevlar reinforced fiberglass covers. Hydraulic test ports are located so the test gauges can be viewed while operating each function. Below the dashboard is the main electrical panel where everything is hardwired to a conventional terminal strip to facilitate easy troubleshooting.
The service brake system has individual circuits for the front and rear brakes, and each has its own brake accumulator to keep the systems properly charged at all times. Should the brake pressure ever drop below specification, a dash-mounted light illuminates to notify the operator.

Service points are placed near the engine.
Direct, dual-control mechanical joysticks are connected right to the HAWE Hydraulics-supplied control valves to command the main boom and frame-sway functions. Fork tilt is controlled by a proportional electric thumb switch on the forward stick, which is intended to provide reliability, as well as precise positive control. The stick that controls the frame-sway features a Y-shaped handle that cradles the operators forearm and allows for one-handed, simultaneous control of all functions. These controls are mounted to a steel sub-assembly that can be adjusted fore and aft to fit the operator's personal preference. The full-suspension operator's seat is modular, so the back or bottom cushions can be individually replaced. One final point: Foam-filled tires are standard on the XRM 1254.
