Konecranes Expand Overhead Crane Line
The latest trolley crane from Konecranes, the Uniton, was developed for customers with applications that fall between the Smarton for process industries and standard industrial cranes. Using a rugged construction concept with multiple trolley configurations and proven components, including Konecranes Core of Lifting (motor + gearbox + control system), Uniton delivers a crane that can be tailored to customers’ unique needs.
Standard features include fabricated box end trucks with 90-degree MCB-type bearing housings that are easy to replace and promote long life. Uniton’s robust design also benefits from Konecranes two-point drum suspension, which inhibits deflections of the rope drum from causing misalignment in the connection between the drum and gearbox.
Uniton cranes are available from Konecranes in a wide range of load options, hoisting speeds, lift heights, trolley gauges, frame sizes, and capacities, from 6.3 to 160 tons with a single trolley and up to 320 tons with two trolleys. They cranes can be built to meet CMAA duty requirements up to Class F.
“In addition to being adaptable and economic, Uniton is also designed to be durable,” said Steve Korsir, VP and director, Konecranes Industrial Crane Solutions, Region Americas. “We included shock load prevention and slack rope prevention as standard features, which helps protect both the crane and load against potential operator error or misuse. The pendant and radio control devices are also designed to handle rugged use.”
The inverter controls comes standard in all motions (bridge, trolley and hoist). Inverter drives provide a smoother lifting experience and reduce wear on mechanical components when compared to contactor-controlled cranes. As an optional feature, Extended Speed Range Plus (ESR+) allows for higher lifting and lowering speeds when loads less than the rated load are handled. When the load is less than 10% of the rated load, the hoist can be operated at up to 250% of the nominal speed, minimizing peak power and energy consumption for a more economical operation.
Optional load control features available include sway control, inching, microspeed, hoist synchronization, and tandem drive, which links the actions of two cranes.
Konecranes designs and builds each UNITON crane for the ambient conditions of the customer’s operation, defined by the application and environment in which the crane will operate. So factors like temperature, humidity and corrosive elements are anticipated during manufacturing, which helps extend the lifetime of the crane.
The UNITON is initially being launched in North America and in selected Asian
countries. The plan is to introduce the UNITON to other countries in the near
