Cat TH514D Specifications
The Caterpillar TH514D telehandler is a modern,
high-performance lifting machine engineered for construction, industrial
handling, agriculture, and infrastructure work. It belongs to the D-Series of
Cat telehandlers, which incorporate updated engine packages, improved hydraulic
efficiency, simplified maintenance, and advanced operator-assistance features.
The TH514D, with a rated load capacity of 4,990
kg (11,000 lb), combines high reach, smooth hydraulic modulation, and
strong structural durability for heavy material-handling operations.
The TH514D is designed to deliver a blend of reach, lift capacity,
control precision, and operator comfort. Featuring a Cat C3.4B Tier 4
Final engine, load-sensing hydraulics, high-performance flow-sharing
valves, and a robust chassis with planetary axles, the machine provides
reliable operation in demanding terrain.
The cab is designed with excellent visibility,
ergonomic joystick control, and optional electronic display systems with
load charts and monitoring functions. Stabilizers increase high-reach
capability, and the machine’s long wheelbase improves stability under
load.
Technical Data
Engine model: Cat C3.4B diesel engine (Tier 4 Final compliant)
Gross power output: 75 kW (100 hp)
Maximum torque: 420 Nm (310 lb-ft)
Displacement: 3.4 L (207 cu.in)
Bore: 99 mm (3.8 in)
Stroke: 110 mm (4.3 in)
The Cat C3.4B engine incorporates electronic fuel management, high-pressure
injection, and aftertreatment technologies to meet Tier 4 Final emissions. It is
oriented longitudinally for simplified service access and cooling efficiency.
The design supports high torque delivery at low RPM, enabling smooth lifting and
steady travel under load.
Air filtration is via a high-capacity air cleaner with service indicators. Fuel
delivery uses a high-pressure common-rail system that ensures responsive
performance and fuel efficiency. The cooling system uses a belt-driven water
pump circulating coolant through a heavy-duty radiator sized for extended
full-load operations. Maintenance layouts prioritize ground-level service
points.
Transmission Type: 4-speed powershift transmission. The
powershift transmission uses hydraulic clutch packs for smooth changes between
gears and directional shifts, allowing precise control during digging, stacking,
and travel operations. The system is tuned for durability under constant load
cycles. The braking system is designed for long service life through oil
immersion, which reduces wear and resists debris contamination.
Forward speeds:
1 - 5.5 km/h (3.4 mph)
2 - 10.6 km/h (6.5 mph)
3 - 25.2 km/h (15.6 mph)
4 - 30.9 km/h (19.2 mph)
Reverse speeds:
1 - 5.5 km/h (3.4 mph)
2 - 10.6 km/h (6.5 mph)
3 - 25.2 km/h (15.6 mph)
Axles
Front axle: high-bias limited-slip differential with planetary final drives
Rear axle: open differential with planetary reduction hubs
RRear axle oscillation provides improved ground contact on uneven surfaces.
Brakes
Service brakes: boost-assisted, oil-immersed multi-disc brakes on both axles
Parking brake: spring-actuated hydraulic release, mounted on the front axle
Battery: 12V, 1000 CCA
Alternator: 120A output
Electrical architecture supports work lights, instrumentation, hydraulic
controls, and engine management systems. The machine supports optional
dual-battery configurations and electrical accessories including reversing
cameras, sensors, and a large operator display.
Drive type: 4x2 (front-wheel drive), with steering on
rear axle
Tires (standard): Mitas 14.00-24 16-ply pneumatic tires
Optional tires: Goodyear air or foam-filled variants
Chassis is a welded steel frame with high torsional rigidity. Underbody
clearance and wheel track width contribute to stability while lifting at maximum
height. Fenders, tow hitches, and protection panels are available for added
durability.
Steering Type: hydrostatic power steering via rear axle
Outside turning radius: 3.9 m (12.9 ft) over tires
Steering responds smoothly with minimal input effort, and geometry is optimized
for confined-space maneuverability on construction or agricultural sites.
System type: load-sensing, closed-center system
Pump type: variable-flow axial piston pump
Maximum pump capacity: 150.8 L/min (39.8 gal/min)
System pressure: 260 bar (3,770 psi)
Auxiliary hydraulic pressure: 240 bar (3,481 psi)
Auxiliary flows:
- Boom head intermittent: 95 L/min (25 gal/min)
- Boom head continuous: 95 L/min (25 gal/min)
The load-sensing system ensures the pump produces flow on demand, improving fuel
efficiency and reducing heat buildup. The flow-sharing valve design enables
simultaneous boom operations, essential for precise load placement at reach.
