Press Release Summary:
Models 247B and 257B combine technology of Cato Skid Steer Loaders and suspended track undercarriage that transfers machine weight to ground through 24-wheeled contact points bearing against 59 in. of track on ground. Operating capacities for 247B and 257B are 1,950 lb and 2,310 lb respectively, when defined as 50% of tipping load. Both loaders use Cat 3024C T engine, which complies with U.S. EPA Tier 2 emissions regulations and provides net power of 57 hp.
Original Press Release:
Caterpillar® 247B and 257B Multi Terrain Loaders Offer Improved Performance, Comfort and Reliability
The Caterpillar 247B and 257B Multi Terrain Loaders feature new turbocharged engines, improved hydraulic forces, redesigned operator station components, and design changes that improve reliability and serviceability. The B-Series machines replace the original 247 and 257.
The Caterpillar 247B and 257B Multi Terrain Loaders are compact, rubber-tracked machines designed for exceptional versatility, flotation, traction, stability and ride quality. The Multi Terrain Loaders combine the proven technology of the Cato Skid Steer Loaders and a suspended track undercarriage. The suspended undercarriage transfers machine weight to the ground through 24 wheeled contact points bearing against 59 inches (1499 mm) of track on ground for very low ground pressure. The undercarriage
remains unchanged in the B-Series.
The 247B is the smallest of the Multi Terrain Loaders with an operating capacity of 1,950 pounds (885 kg), when defined as 50 percent of tipping load. The 257B operating capacity is 2,310 pounds (1047 kg) at 50 percent tipping load. Both loaders now use the responsive Cat 3024C T engine, which complies with U.S. EPA Tier 2 emissions regulations. Net power is 57 horsepower (42 kW) in each machine.
Both B-Series models have greater hydraulic system performance than the models they replace. Standard flow is 15.6 gpm (60 L/min) and maximum pressure is 3,355 psi (23 000 kPa). The high flow option available on the 257B boosts flow to 26 gpm (100
L/min) and hydraulic horsepower increases 40 percent for highly productive operation of hydraulically powered work tools.
The 247B and 257B offer significantly greater breakout forces than their predecessors for aggressive digging capabilities. The 247B has radial lift linkage, and the 257B features vertical lift linkage for improved loading and materials handling capabilities. Maximum pin heights are 112 inches (2862 mm) and 119 inches (3018 mm), respectively.
B-Series improvements for all models
The B-Series machines employ the proven anti-stall system and pilot hydraulic joystick controls that make Caterpillar Multi Terrain Loaders easy to operate. B-Series improvements include a deluxe joystick design that incorporates positive-action buttons
to control work tool hydraulic or electrical functions. An ergonomically designed arm bar is rounded and sculpted to provide superior operator comfort, and the redesigned gauge
panels are easy to read. The B-Series cab offers a new door option with 25 percent more glass that improves sight lines to the working area. The new door also incorporates a new loader lock out function that prevents loader arm movement when he door is open. A standard convex rearview mirror gives the operator a wider view behind the machine, and the lights are now adjustable 10-degrees up and down as well as side-to-side.
The improved B-Series hydraulic system design reduces the number of potential leak points and improves reliability and cleanliness. A 5-micron spin-on filter keeps hydraulic
oil clean, and a high-efficiency hydraulic oil cooler allows the machines to work smoothly in high ambient temperatures.
Ease of service is designed into each B-Series machine. The rear service door opens 90 degrees for easy access to both sides of the in-line-mounted engine. The loader is configured for straightforward access to the oil filter and air cleaner as well as fluid level check points. The cooling fan and air conditioning compressor are hydraulically driven to
eliminate the maintenance required by belt drives. A higher alternator rating and battery rating improve reliability, as does a simplified wiring harness. For access to hydraulic
pumps, motors and valves, an individual can tilt the cab rearward by using a single tool. A self-latching mechanism holds the cab in place.
With five different Cat B-Series Multi Terrain Loaders to choose from, selecting the right machine for the job is made easier by consulting the local Caterpillar dealer or by using the Build and Quote application on-line. Both the Cat dealer web site and www.cat.com offer Build and Quote, which enables the customer to configure features for his requirements, review MSRP and request a custom quote from the local dealer.
