Description

Features
The Metso Balance Crane is a low-energy, electrically operated crane made in the USA.
Incredibly versatile, it can effectively handle bulk material, general cargo, scrap metal and containers with ease. With its unique counterbalance principle, both the machine weight and a significant portion of the lifted load are balanced at any given point of the duty cycle.
The closely balanced crane uses 50% less energy.

Benefits
Smooth operation
Long reach
Precise positioning
Low energy
Low maintenance

How it works?
The system has been designed so that the hydraulic cylinders only have to lift half of the load while the counterweight deals with the other half. The Metso Balance Crane is based on a unique counterbalancing principle. The boom, stick, connecting link and counterweight form a parallelogram. This ensures that the weight of machine and a portion of the lifted load are balanced at any point in the duty cycle. This results in 50% less energy to move the lifted load. It is up to 80% more energy efficient than comparable hydraulic excavators. Because the crane is so closely balanced about the slewing ring, foundation requirements are minimized. Cranes have routinely been mounted on a single large diameter pile or small cell. The crane is easily adaptable to crawler mounting or on railmounted undercarriages.

Applications: Electric power – coal and limestone handling, crushed stone – transfer to river barge or rail transport, scrap recycling – feeding shredders, filling shears and loading charger baskets, dredging – sand/rock at port facilities and terminals, industrial minerals, cereals and grains – loading and unloading
