High Performance Machines for Steel Mill Maintenance
Steel mill maintenance is dirty, hot, rugged work in extreme environments. Gradall and LAG steel mill machines are engineered and manufactured with this environment in mind. The machines’ boom range, swing, and tilt rotation movement allow for precise control, whether performing ladle or BOF furnace maintenance or tap hole cleanout and replacement in confined or crowded work areas.
- Powered by a single Volvo engine that meets the highest global standard Stage 5 emissions requirements
- Crawler or rough terrain rubber tire undercarriage
- On crawler models, dual range high torque piston motor powers each track, along with three-stage planetary drive, integral speed limiting valve and automatic spring-set hydraulic release wet disc parking brake
- Triple grouser crawler excavator pads available in a choice of widths enhance tracking ability, with high range travel speeds up to 3.4 mph
- Tracks counter-rotate to pivot machine about the swing centerline
- Single-point lifting yoke available
- Stainless steel braided hose and fire sleeves
- Crawler tracks and foam filled or solid rubber tires are fire resistant
- Heat resistant shields protect rubber tires
- Wheeled models have oscillation lock cylinders and strong box plate construction, enabling work in any direction without outriggers
- Heavy-duty boom rollers, along with an exceptionally rugged boom and tilt motor at rear end of the boom
- Full boom performs 360° continuous rotation for efficient prying action at any angle
- Internal metal hose and tube clamps
- No loss of power to attachment tilting capability
- Consistent boom force
- Rugged boom telescopes out up to 52’
- Low profile telescoping action, reaching deep into furnaces
- Full-length boom visibility during the entire dig cycle
- Choose the Gradall, Deere or SAE joystick pattern using an in-cab switch
- Quiet, roomy cab and comfortable seating module, with joystick controls built into the armrests
- Internal tooth swing bearing provides smooth, stable movement
- Two electronic foot pedals with handles reposition carrier, using toggle switch on arm pod to select from two crawler speed ranges
- Excellent visibility of the boom through the entire working cycle
- Standard air conditioning
- Optional rollover protection
- Window guards
- High temperature glass
- Legendary Bosch Rexroth design and reliability
- All new, modern high-pressure hydraulic system is electronically controlled with pressure-compensated, load-sensing valves
- Combined electrical system for chassis and excavator delivers advanced, effective operation
- Short tail swing to maneuver and work in tight quarters
- Heavy frame for lateral support
- Heavy boom cradle
- Crawlers have thicker grouse pads for work at the side of the carrier
- Triangular telescoping boom design delivers full power and speed through the working range
- Electronic joysticks provide precise control over boom and attachment positioning
