Benefits & Features
Caterpillar M325B Wheeled Material Handler
M325B MH Two-piece Fronts
- Caterpillar booms and sticks are built for performance and long service life. Welded box-section structures feature thick, multi-plate fabrications in high stress areas allowing structures to flex, dissipating stresses and maximizing strength. Booms and sticks are stress relieved to maximize strength and minimize structure weight.
- The 15.5m front offers a maximum horizontal reach of 50'10" from swing center and a maximum vertical pin height of 17.0m (55'7")
- The 13.4m front offers a maximum horizontal reach of 43'11" from swing center and a maximum vertical pin height of 15.3m (50'4")
1.9m (6'5") Cab Riser
Cat designed and built riser gets your operator to an operating height with excellent visibility for loading or unloading your processing equipment, trucks and rail cars. Access to the cab is provided by a platform which extends around the riser to allow windshield cleaning. The cab riser can also be tilted forward 90º for shipping and provides ready access to service the generator system.
Cat Material Handler hydraulic systems
Auxilliary hydraulics are specifically designed to meet your hydraulic attachment requirements. The rotate circuit provides a separate 30.0 lpm (8.0 gpm) gear pump and fully adjustable control valve, allowing configuration to meet various grapple manufacturer's flow requirements. A separate fixed displacement gear pump is used to provide the hydraulic power to run a 20 kW generator system.
The Upper Frame
The heavy-duty upper frame is specifically designed for the scrap and material handling market, the upper frame is built of higher strength material and thicker steel sections to handle the increased swing loads developed with the longer fronts and heavier counterweights used in material handling.
Special Counterweight
The M325B MH is equipped with a counterweight which is 50% heavier than the standard counterweight.
20 kW hydraulically driven generator set
This exclusive Caterpillar genset can power magnets up to 1702 mm (67") in diameter. A Caterpillar state-of-the-art electronic magnet controller and generator are linked to provide trouble-free service. The new controller completely eliminates traditional contactor maintenance and is supported and warranted through your Cat dealer.
M325B MH Wheeled Carrier
The carrier of the M325B MH has four wheel hydrostatic drive and two wheel steer. The fabricated frame has a trunnion mounted front drive steer axle and solid mount rear drive axle. A hydraulic front axle stabilizer locks in any position with plus or minus four degrees of oscillation. Front axle and parking brakes are hydraulic disc, while rear axle brakes are hydraulic drum. The two-speed powershift transmission provides a maximum drawbar pull of 14,830 kg (32,700 lb.) and a maximum travel speed of 19.8 km/hr (12.3 mph).
Controls
- The M325B MH features:
- Steering wheel with tilt steering column
- Independent or simultaneous outrigger controls, axle oscillation parking brake, transmission shift and high and low speed ranges.
- Service brake and forward reverse pedal are left and right of the steering column.
Millyard Applications
Heel Boom Front
The Caterpillar 12.2m (40')heel boom front with bottom mounted heel cylinder is available as a dealer installed kit. This arrangement fits a wide variety of log handling and loading applications in millyards. Heel booms are especially well-suited for use with large diameter sawlogs.
30" Cab Riser
The .76m (30") cab riser option provides a lower cab riser as compared to the 1.9m (6'5") riser. This arrangement results in a cab height of 4.78m (15'8") when equipped with the optional Falling Object Guard, which is ideal for millyard applications. This riser also provides an access system from the ground on the left side of the machine and can be manually tilted forward 90° for lower shipping height.
Butt-N-Top (B-N-T) Front
The Caterpillar Butt-N-Top log loader arrangement is available as a dealer installed kit. This arrangement provides an 11.3m (37') maximum reach front which can accept the dealer-installed butt-n-top grapple. It is ideal for charging millyard endfeed conveyors where sorting butts and tops is required and off-loading logs from trucks directly into high storage decks.
