Concrete plant manufacturer standardises on new speed reducer 16 July 2010

CON-E-CO (Concrete Equipment Company) in the US is the first OEM to standardise on the new Baldor-Dodge Motorised Torque-Arm II shaft-mounted speed reducer – receiving the first units straight off the assembly line.

The company, which manufactures a range of portable and stationary concrete batch plants, has used Baldor-Dodge bearings and torque-arm reducers for many years, and says it likes the engineering.

"Because of my experience with the original torque-arm product, I understood the level of engineering that went into the new MTA," says Don Hansen, CON-E-CO engineering manager. "When we saw the capabilities of the MTA, we knew this was the right product for us."

The new design has no exposed sheaves or V-belts, which adds an additional level of safety to the product. It is also compact. "It's powerful, but it takes up less space," says Hansen. "It fits into some of our smaller spots on the batch conveyor, and this works so much better for us."

The new MTA shaft mounted speed reducer is a right-angle gearbox with a flanged motor interface, specified for use with two-pole or four-pole motors. There is a choice of 12 gear reduction ratios and three case sizes, covering from 18:1 to 75:1 for class 2 applications, from 3 to 55kW – with efficiencies up to around 95%.
