New features for IMT articulating cranes

Iowa Mold Tooling Co. Inc. (IMT) in the US has introduced new articulating cranes and added features to existing models. Seventeen of the company's 22 articulating crane offerings are new or improved, with lift capacities ranging from 1,740 pounds (790 kg) to 35,405 pounds (16,060 kg) maximum rating at a radius of 14 feet 5 inches, according to the company.

"We have added new models and reclassified many of our current models to better reflect their capabilities for matching our customers' particular needs," said Steve Fairbanks, president. "We recognize that the customer wants as many crane choices as possible, and we also affirmed our customer commitment by soliciting input and incorporating many of their suggestions into our new designs."

One of the most significant changes to the product line is the addition of eight mid-range cranes with SL (single link) or DL (dual link). The single power plus link arm system provides high lifting capacity when the boom is fully extended and offers strength, regular speed and flexibility in the outer boom combined with high speed in the main boom's extreme positions at the column. This system features high speed in extreme positions at the column, which makes the boom system ideal for fast-grab work, according to the company.

The dual power plus link arm system offers precise and regular movements in the entire working area, and is particularly well-suited for long reaches and lifting in high positions with demanding equipment (such as fly-jib and winch), the company claimed.

Another new feature is "over-bending," which means the working area between the main boom and the jib is no less than 195 degrees. Over-bending offers greater flexibility when working through narrow passages and under overhead power lines, the ability to lift maximum loads in all boom positions, and a lower total height when the crane is stowed on the truck body.

A key safety feature, available on all models, is the rated capacity limiter (RCL), the company said. Mid-range and larger cranes are available with the newest generation RCL 5300. The RCL monitors the crane's load moment, operation and function. In an overload situation, the system warns the operator and interrupts the distribution of oil for crane functions, while allowing functions that reduce load moment to remain operational.

"These new models build on the successful product platform IMT already has in place," Fairbanks said. "They maintain the high quality standards our cranes have been known for while elevating the technology."

Additional articulating crane features of the new models 13/88 through 24/169 include a new internal hose routing system; a flexible stow bracket design that secures the boom for transport but does not allow bracket damage; and minimised width that saves space on the overall platform length.

Features of the IMT range include a hexagonal boom profile; load-holding valves; an extension system with a regeneration valve to increase working speed; and high tensile steel, which provides lower weight, high lift capacity at long reach and increased payload.
