Expanding its wheel loader lineup, Terex Construction introduced its new TL210 compact wheel loader during ConExpo 2008. Building upon the successful design of the company’s popular TL260 compact wheel loader, the TL210 features a spacious operating cab, heavy-duty chassis, Terex cooling system with reversible fan, U.S. EPA Tier-3-compliant engine, and modified toolcarrier linkage.
Powered by a Cummins QSB 6.7 engine that delivers 162 hp (120 kW) at 2200 rpm, the new loader is designed for quiet, low-vibration operation. Mounted transversely, the six-cylinder turbocharged diesel features common-rail fuel injection for high performance, maximized fuel economy, and low emissions.
Power transmission in the TL210’s hydrostatic drive unit is carried out via a closed-circuit hydrotransmatic transmission with two regulating motors and a pump, marking the first application of this technology in the Terex midsize wheel loader range. The transmission automatically optimizes traction force and infinitely variable speed—with no interruption—throughout the TL210’s entire speed range of 0 to 25 mph (0 to 40 km/h).
Four-wheel drive is provided from the reduction gear on the rear axle to the front axle via the driveshaft. The rigid planetary final drive front axle has a limited-slip differential, and the oscillating planetary final drive rear axle has an integrated reduction gear with limited slip-type differential.
The new loader’s hydraulic system is controlled by a proportional hydraulic valve with three control circuits that provide simultaneous, independent control of all movements. A single four-way multifunction control lever with integrated travel selector switch controls one tilt and two lift cylinders. The system provides a maximum pump capacity of 42.3 gal/min (160 L/min) and a maximum working pressure of 3916 psi (270 bar).
Fully hydraulic center-pivot steering, a proven standard in combination with a rear-axle oscillating function, provides stable, effective control. Load-sensing hydraulics from Bosch Rexroth provide load-independent flow distribution for smooth operating cycles that are powerful, yet non-jolting, and rapid steering movements even at low engine revolutions.
The TL210’s loading system is equipped with the company’s modified toolcarrier linkage, which combines the advantages of Z kinematics, including powerful breakout force and bucket reaction force, with the precise parallel control of parallel kinematics in the bucket and forklift attachment. The loader delivers a lifting force of 27,740 lb (123.4 kN) at ground level and a breakout force of 23,830 lb (106 kN) at the bucket’s cutting edge.
Delivering competitive loading in a compact package, the TL210 at 8.2 ft (2.5 m) wide and 10.7 ft (3.3 m) high moves a payload of 4.35 ton (3.95 t) direct-mounted with a 2.75-yd³ (2.1-m³) bucket. Payload over the entire lift and steering range for forks is 4.96 ton (4.50 t). Providing a notable advantage for applications in recycling plants, mixing plants, timber processing, paper plants, and the agriculture industry, the Terex TL210 offers a discharge height of 9.9 ft (3.0 m) at an angle of 45°.
The TL210’s radiator system features a wire screen installed in front of the high-volume cooler for protection from grit. The air intake is strategically located in the dust-free zone behind the driver’s cab, and a system fan automatically and periodically switches to reverse to remove fine grit and clear out the system, thus reducing the amount of required maintenance.
Designed for operator comfort, the new Terex TL210 compact wheel loader’s rubber-mounted cab offers a range of features including tinted panoramic safety glass for high visibility through a range of operating conditions and an accessible two-door entry system. Additional ergonomic features include an operator’s seat with hydraulic shock absorption, automatic climate control with air-conditioning, tilt- and height-adjustable steering wheel, and a sliding window at the operator’s left side.
