July 2012, Putzmeister introduces its new Telebelt® TB 200, a technologically advanced, feature-rich telescopic belt conveyor that outmaneuvers, outdrives and outperforms other competitive placing systems used for a broad range of high volume applications. After completion the huge machine will be shipped to Panama for placing concrete on the Panama Canal Expansion Project.

“As the newest addition to our Telebelt line, the TB 200 offers a multitude of advantages that make it a better conveying system than what is currently available in the market,” says Bob Weiglein, Putzmeister Telebelt® Division Manager. “From its increased working range, maneuverability and shipping convenience, to lower counterweight requirements, more power options and fewer wear parts, we really have everything covered.”

Designed to save time and money
With a four-section boom that retracts to 74-feet, nine-inches (22.80m), the TB 200 provides an increased working range of eight percent over the competition so the Telebelt doesn’t require being moved as often, saving precious job site hours. When there is a need to move the Telebelt, its shortened conveyor length when retracted allows for easier movement around the job site.

Since the chassis is road-legal, it can be driven (up to 50 mph [80 km/h]) to locations instead of being transported on a flatbed, saving both time and money. The improved chassis, which can also be driven off-road, features front, rear, coordinated and crab steering with a tight turning radius for necessary job site maneuverability.

The TB 200 distributes its weight over five steerable axles, which reduces the load per tire for longer life and reduced service requirements. Additionally, this results in the TB 200 moving easily around the job site without the assistance from other equipment.

Boom has less weight, more strength
The TB 200 has an advanced boom design that is stronger, yet a full 6,000 pounds (2,722kg) lighter than the competition. Extruded steel tubes – the strongest shape design due in part to the lack of weld seams – comprise the modern lattice boom structure.

In addition, the TB 200’s belt uses only two rollers in a “V” configuration, versus three, which results in fewer wear parts and greater material control. The rollers, in addition to the sheave and slide pad technology, are common to the rest of the successful Telebelt line.

Powerful, efficient performance
The TB 200 is powered by two different engines. The first engine with 503 hp (370kW), located in the chassis, is used for transport and outrigger deployment. The second engine, a self-contained Deutz TCD 2015, 450 hp (330kW) engine, powers all functions related to the conveyor and belt. The Deutz engine can be changed depending on job site requirements. “To prevent the chassis from being driven while someone is operating the boom, or viceversa, the two engines cannot run at the same time, ” explains Weiglein. “The operator flips a switch in the cab after the chassis is in place and outriggers are deployed which then allows the conveyor operations to begin.

Offering superb engine efficiency, the TB 200 uses hydraulic drive, which pulls power from the engine at varying rates depending on the belt load. With an empty belt, less power is needed, resulting in fuel efficient operation. It is important to note, the belt speed remains the same even though power from the engine varies.

The efficiencies continue with remote control of the hydraulic belt speed. Unlike the competitor’s unit, which requires the operator to stop working, turn off the belt and manually adjust gears on the boom, the belt speed on the TB 200 can be quickly adjusted remotely and on-the-fly to match changing job site requirements and fine-tune material delivery.

Innovative counterweight technology
Putzmeister has engineered the TB 200’s counterweight as a structural element of the unit. The counterweight moves proportionally in and out as the boom extends and retracts, ensuring that the right amount of weight is in the right position to offset the load of the boom.

“The counterweight is manufactured out of steel which helps maintain quality control standards on such an integral component,” says Weiglein. Separated into three pieces, the counterweight totals 29 tons as compared to the competitor’s single 40-ton unit. Weighing 11 tons less makes transporting, setting up and operating the TB 200 much easier and less costly.

“The benefits of this are two-fold - the lighter counterweight decreases the weight on each axle, which prevents wear and tear on the axles, and it costs significantly less to ship,” explains Weiglein.

Conveying versatility
With a horizontal reach of 200 feet (60.90m) and 24-inch (610mm) belt width, the TB 200 places materials sized up to six inches (150mm) at an output of 5 yd3/min (4m3/min), making it ideal for large aggregate, mass concrete placement. It is adaptable in a variety of applications, from hydroelectric dams and power plants to breakwater structures and high speed rail construction.
