User manual CATERPILLAR CM240 BROCHURE

[. . . ] So whether you're in full trenching mode, or delicately digging around services, you are in control. In applications such as production trenching, speed is important and the system will match the flow needed to get the job done quickly and efficiently. The load-sensing hydraulic system also delivers: · · · · A cooler hydraulic system Better fuel efficiency Quieter operation Reduced wear on components Cat XT-3 ES ToughGuardTM hoses combined with Cat couplings and O-ring face seal fittings provide a leak-free system. The 420E also features new flow-sharing hydraulic valves, ensuring proportional flow of oil to all hydraulic cylinders, providing greater control and improving multifunction performance. Ride Control Delivers even greater operator comfort. The optional Ride Control System smooths the ride in all conditions, including load and carry, highway roading, or simply moving around the job site. [. . . ] Four Wheel Drive (4WD) option improves mobility and loader performance in poor underfoot and can be activated on-the-go. Maximum roading speed of 40 km/h (25 mph) for faster travel between job sites. Cat Rear Axles are designed specifically for demanding backhoe loader applications. Axles feature outboard planetary gear sets for easy serviceability and brake design improvements for longer service life. · · Brake Mode Selector The brake mode selector switch has three positions: two wheel drive, two wheel drive with all wheel braking and four wheel drive. Two wheel drive with all wheel braking provides better tire life while roading and engages the front axle when brakes are applied for improved braking performance. 5 Loader Choice of loader linkage to meet your needs. Caterpillar offers a choice of single tilt or integrated toolcarrier (IT) loader linkage to suit your application requirements. The IT loader controls provide single lever proportional control and fine modulation of the hydraulic work tools. A thumb roller operates auxiliary hydraulic functions such as the multi purpose bucket on the IT machines. Single Tilt The standard single tilt loader linkage features strong lift and breakout forces for solid performance in backfilling and truck loading applications. Integrated Toolcarrier The optional integrated toolcarrier (IT) loader linkage provides higher breakout forces, as well as parallel lift, for efficient loading and material handling. Integrated toolcarriers are highly versatile and can use a wide range of Cat Work Tools for a variety of applications. Return-to-Dig The return-to-dig system reduces loading cycle times by bringing the loader bucket back to the dig position with an easy pull of the lever. By the time the loader bucket is at ground level, the bucket is angled correctly for the next load or cut. 6 Backhoe Boom and stick designed for high performance and easy service. The E-Series backhoe delivers industry-leading digging forces. Serrated edges on the stick provide improved material clamping for clearing and demolition applications. The single pin bucket linkage contributes to best-in-class rotation of 205 degrees for all applications. E-Stick Design The optional extendible stick (E-stick) increases reach and dig depth by approximately 1. 2 meters (4 feet). · Used 35° API gravity fuel having an LHV of 42 780 kJ/kg (18, 390 BTU/lb) when used at 30° C (89° F) (reference a fuel density of 838. 9 g/L [7. 001 lb/gal]). 11 420E/CM240 Specifications Loader Bucket Capacity ­ General Purpose Bucket Width ­ General Purpose Dump Height @ Max Angle ­ Single Tilt Dump Height @ Max Angle ­ IT with QC Dump Reach @ Max Angle ­ Single Tilt Dump Reach @ Max Angle ­ IT with QC Dig Depth ­ Single Tilt Dig Depth ­ IT with QC Lift Capacity @ Full Height ­ Single Tilt Lift Capacity @ Full Height ­ IT with QC Bucket Breakout Force ­ Single Tilt Bucket Breakout Force ­ IT with QC 0. 96 m 3 Hydraulic System 1. 25 yd 3 Power Train Power-Shuttle, Forward 1st Forward 2nd Forward 3rd Forward 4th Power-Shuttle, Reverse 1st Reverse 2nd Reverse 3rd Reverse 4th Auto-Shift (opt), Forward 1st Forward 2nd Forward 3rd Forward 4th Forward 5th Auto-Shift (opt), Reverse 1st Reverse 2nd Reverse 3rd 6 km/h 9. 6 km/h 20 km/h 40 km/h 6 km/h 9. 6 km/h 20 km/h 40 km/h 5. 9 km/h 9. 5 km/h 20 km/h 27 km/h 41 km/h 5. 9 km/h 13 km/h 27 km/h 3. 7 mph 5. 9 mph 12 mph 25 mph 3. 7 mph 5. 9 mph 12 mph 25 mph 3. 7 mph 5. 9 mph 12 mph 17 mph 25 mph 3. 7 mph 7. 8 mph 17 mph Circuit Type Pump Capacity (@ 2, 200 rpm) System Pressure ­ Backhoe System Pressure ­ Loader Pump Type Steering Type Power Steering 2WD Cylinder ­ Bore Stroke Rod Diameter 4WD Cylinder ­ Bore Stroke Rod Diameter Brake System 2262 mm 2573 mm 7 ft 5 in 8 ft 5 in Closed center, load sensing 163 L/min 43 gal/min 24 900 kPa 3, 611 psi 22 800 kPa 3, 307 psi Variable-flow, axial piston Front wheel Hydrostatic, HMU 65 mm 2. 6 in 120 mm 36 mm 65 mm 4. 7 in 1. 4 in 2. 6 in 2507 mm 8 ft 3 in 853 mm 831 mm 106 mm 147 mm 2929 kg 3164 kg 45. 6 kN 47. 1 kN 2 ft 10 in 2 ft 9 in 4 in 6 in 6, 457 lb 6, 975 lb 10, 242 lb 10, 593 lb 120 mm 4. 7 in 36 mm 1. 4 in Inboard, oil-immersed, multiple disc · Auto-Shift automatically shifts between · Forward/reverse electric power shuttle second gear and highest selected gear. is controlled by a conveniently placed, hand operated lever that provides instant direction changes between forward and reverse through power hydraulic clutches. · Torque converter free-wheel clutch allows the converter stator to free-wheel during high speed, low torque conditions such as roading. · Travel speeds of two wheel drive backhoe loader at full throttle when equipped with 19. 5 × 24 rear tires. 12 Operating Specifications ­ Backhoe Turning Circle: 8. 18 m outside, front wheels Turning Circle: 10. 97 m outside, widest loading bucket 26 ft 10 in 36 ft Axle Ratings Front Axle, 2WD, Static Dynamic Front Axle, 4WD, Static Dynamic Rear Axle, Static Dynamic Axle Oscillation 22 964 kg 9186 kg 22 964 kg 50, 582 lb 20, 233 lb 50, 582 lb Tires Choices listed as combination of front/rear tires: · 11L-16 (12 ply) F-3/19. 5L-24 (12 ply) · 12. 5/80-18 NHS (12 ply) 1-3 Super · 12. 5/80-18 NHS (12 ply) 1-3 Super Traction/21L-24 (16 ply) R4 ATU R4 ATU R4 ATU Traction/19. 5L-24 (12 ply) R4 ATU · ISO 5010.
