Built with many of the same features as the TG9000 tub grinder, Vermeer’s TG7000 tub grinder handles large landclearing projects and organic wood/waste processing applications.
The TG7000 uses a Cat 3412 E powerplant with twin turbocharged air-after-cooled engine. Two engine options are available: 1,000 hp (746 kW) or 860 hp (641 kW).
A non-loader machine weighs approximately 73,500 lbs. (27,433 kg). A machine equipped with the loader feature also is available and weighs approximately 84,500 lbs. (38,409 kg). The gross weight of the TG7000 — with or without the loader —makes it suitable in any state or province.
Other available options include mechanical or air-ride suspension, and wheel assemblies with steel hub piloted duals or aluminum super singles — which provide increased ground clearance and better traction for off-road site development applications.
The TG7000 features a self-tensioning, maintenance-free tub drive chain. The unit has an inside tub diameter of 10 ft. (3 m), a depth of 56 in. (142 cm), and an 11-ft., 4-in. (3.45 m) loading height. A 13-ft. (4 m) tub flare makes loading large and bulky materials easier.
The tub table lifts more than 90 degrees for easy tub cleanout and millbox access.
The Thrown Object Restraint System (TORS) combines a tub cover and rotor deflector, reducing the quantity and distance of thrown objects. The tub cover is hydraulically operated for effortless operation and transport positioning.
The tub grinder also features the Duplex Drum system. This cutting system offers optimum cutting performance with reduced maintenance. Maintenance time is reduced as a result of protection provided by the drum skin to the hammers. Eleven hammers and 22 double-bolt cutter blocks, which are components of the center drum cylinder, are reversible and may double the life of the hammer.
Clutch pressure is maintained by oil pressure, which eliminates the need for clutch adjustment. The clutch runs in oil to stay cool, resulting in higher efficiency due to limited slippage.
A one-piece continuous flow conveyor belt measuring 48 in. (122 cm) wide is part of a discharge system that handles more material with less clogging and can run at speeds up to 860 ft. (262 m) per minute.
If the machine becomes mired down on the job site, the integral push and tow plates mounted on convenient locations on the rear of the continuous grade 80 I-beam frame allow the TG7000 to be easily towed or pushed.
