Maxwell ultracapacitors support Caterpillar's hydra-electric technology in the industry's largest-ever hydraulic mining shovel
Maxwell Technologies, announced that it is supplying ultracapacitors to Caterpillar for a high-efficiency energy management system that supports Caterpillar's fuel-saving hydra-electric technology in the industry's largest-ever hydraulic mining shovel, the new Cat® 6120B H FS. The 1,400-ton shovel's innovative energy management system incorporates 98 of Maxwell's 125-volt ultracapacitor modules to efficiently absorb energy during brief shovel movements and rapidly deliver stored electrical energy on demand to supplement the main power system. "Caterpillar's use of ultracapacitors to support this energy-saving technology in the mining industry is a further demonstration of the versatility of our products across an increasingly diverse spectrum of industrial and transportation applications," said David Schramm, Maxwell's president and chief executive officer.
