MOTEUR
Designed to Excel
BENEFITS AND FEATURES
Built by the World Leader As the world’s leading supplier of longwall technology, Caterpillar has always striven to design and manufacture the best longwall movers possible. Our outstanding experience in the development and design of rubber-tired vehicles has contributed to the success of our four-wheel roof support carriers.
Built for the Future All Cat roof support movers are built to meet both current and future requirements in longwall moving by providing a combination of compact power, capacity, maneuverability, long-term availability, and efficiency.
Built to Be Best After studying operations all over the world, we selected the best concepts and designs for the varying conditions and regulations encountered in underground coal mines. Caterpillar offers a range of roof support carriers designed to provide maximum lift and carrying capacity at dimensions adequate for our customers’ different mine layouts and for various transportation tasks.
Heavy Lifting
BENEFITS AND FEATURES
Industry’s Highest Rated Lift Capacity The SH650’s 45-tonne (50-ton) lift and carry capacity meets all your longwall handling needs now and for the foreseeable future. The massive 1829 mm × 356 mm (6 ft × 14 in) forks are retained to the lift frame structure by 102 mm (4 in) diameter steel pins. The forks are heat-treated forged steel. The lifting frame is high-strength alloy steel with bushed pivot points.
Perfect Positioning The unique lift and tilt mechanism allows the operator to manipulate the lift frame into an infinite number of positions to facilitate placement and handling of the load. The range of motion of the lift has increased by 133% allowing the load to be engaged more easily by reducing the angle between the lift frame and the grade. This reduces the stress on the winch and the drive train.
Packed with Power
BENEFITS AND FEATURES
Clean Air Act Cat battery-powered roof support carriers do not burden your mine’s ventilation system with emissions or heat. Due to infinitely variable power control, they are the ideal vehicle for the installation or removal of longwall roof supports where heat, emissions and noise would impact work and where a flexible vehicle is needed.
Power to the Max As the world leader in longwall systems and battery-powered vehicles for underground mining, we take pride in providing the world’s most advanced battery-powered roof support carriers. Innovative solutions in power control and transmission contribute to utilizing battery power to the max.
Battery Competence Caterpillar has developed unparalleled experience and expertise in the design of batteries and battery changing systems. Current 2000 Ah batteries enable maximum performance at peak loads as well as lasting performance throughout the shift. Battery capacities and vehicle designs are field-proven and are adapted to actual work schedules and Iongwall move experience.
High Performance, Low Cost of Ownership The Cat East Penn battery is built for the long run, providing the lowest cost of ownership in the industry. Specially formulated premium-grade lead oxide is used in the flat-plate design and each plate is individually formed prior to cell assembly. This ensures uniform performance and maximum capacity. State-of-the-art computerized equipment is utilized in every phase of the production process and stringent quality checks are made on each battery to ensure the highest level of performance.
A Solid Performer
BENEFITS AND FEATURES
Stability, Traction… One of the key features of the SH650 VFD design is the tri‑sectional chassis incorporating the rear drive axle and battery lift into a single oscillating entity. As load motion is independent of the rear frame, this design provides extra load handling stability, especially on uneven ground or when maneuvering and positioning roof supports - even when handling loads equal to the empty vehicle weight. It also improves traction, as wheels remain in contact with the ground with the weight of the battery over them.
…and Maneuverability The SH650 VFD offers the unique feature of 100 degrees of articulation for maneuvering heavy loads in the confined spaces encountered during longwall moves. The use of through-hardened precision-ground spherical plain steel bearings ensures the smooth transfer of energy through the bearing to the articulation pin and load distribution throughout the contact length.
Superior Control
BENEFITS AND FEATURES
Maximum Battery Efficiency The Cat IGBT control makes the most of battery power. It translates to variable speed and tractive effort at the varying intervals. This allows battery power to be controlled with maximum precision and efficiency.
Optional VFD The HiPAC 10 VFD control system is a Caterpillar innovation that drives the traction and hydraulic systems and provides the operator with machine management information.
High Efficiency The HiPAC 10 is a DC-to-AC variable frequency inverter control that drives high-performance AC electric motors, which have superior speed-torque characteristics. It is up to 14% more efficient than traditional DC motors. This means higher loaded tram speeds, more responsive hydraulic functions and more material hauled per battery charge. The HiPAC 10 machine management system speeds fault diagnosis, allowing rapid repairs and maximizing uptime. The new user interface can display information such as drive unit temperatures and distance traveled per battery charge.
Intuitive Control The optional Cat control stick gives the operator intuitive control over steering and other functions. It also gives quick access to monitoring and self-diagnosis of the vehicle’s functions.
Operator-Friendly Control Compartments
BENEFITS AND FEATURES
Safe Working Environment The operator’s comfort is paramount for maintaining a safe working environment. Controls are logically placed, and easy to reach from the padded, adjustable seat. Directional control inputs are applied with the left hand which (depending on options chosen) also incorporates a user interface allowing control of many functions.
Maximum Visibility and Clearance The frame is contoured with the top sloping from the center to the outside to promote visibility around the vehicle’s perimeter. The decks taper from the center upwards to the outside to ensure maximum ground clearance. This combination provides for a machine that has surpassed its predecessor in every way except in growing in shear size and complexity.
Clean Machine
BENEFITS AND FEATURES
Ideal for Longwall Moves Zero emission of noxious gases and low emissions of heat and noise make the carrier range operator-friendly and easy to work with - in short, the ideal utility vehicle for longwall moves. Heavy lifting and perfect positioning, versatility and maneuverability all combine to make this the world’s most advanced battery-powered roof support carrier.
