New IMT knuckle booms

US equipment manufacturer Iowa Mold Tooling Company (IMT), part of the Oshkosh Corporation, has launched four new articulating crane models: the 610, 710, 810 and 910.

The new models replace the 5/33, 6/39 and 7/48 models and IMT said they offer increased lifting capacities in the 5 to 10 tonne-metre range.

The new models have the Electronic Vehicle Stability (EVS) system. IMT said this is designed to increase operator safety. EVS monitors the stability of the crane and warns the operator when the tilt of the truck’s chassis approaches a pre-set angle. The EVS system integrates with a rated capacity limiter (RCL) – a safety component that monitors and limits the crane’s load moment, operation, and function. According to IMT, the EVS and the RCL work together to create an integrated system that ensures truck stability so that the crane can be used at available capacity in any vehicle setup without jeopardising safety. Additional new features include internal hose routing, a ‘j’ stow hook, and improved lift-to-weight ratio on all models.

The new models also retain all the key features of previous models, such as over-bending, which IMT said ensures the working area between the main boom and the jib is no less than 195 degrees.

“Between the increased lifting capabilities and the EVS and RCL, customers can maximise their productivity without worrying about safety — the system monitors what is happening for them,” explained John Field, articulating crane product manager at IMT. “These new models will significantly impact the productivity capabilities of operators.”
