Iowa Mold Tooling Co., Inc. (IMT), an Oshkosh Corporation company, introduces its new 40 tm and 50 tm models to its lineup of truck-mounted articulating cranes. These cranes feature excellent lift-to-weight ratios, long-reach capabilities, and minimized space requirements, according to the company. The new cranes replace the 34 tm, 38 tm, 42 tm and 47 tm models in the IMT articulating crane lineup.
The 40/275 crane provides a maximum lifting capacity of 19,026 pounds (8,630 kilograms), while the 50/345 model delivers a maximum lifting capacity of 22,840 pounds (10,360 kilograms). The 40/275 and 50/345 models can be equipped with up to eight hydraulic extensions for maximum horizontal reaches of 69 feet 11 inches (21.3 meters) and 70 feet 3 inches (21.4 meters), respectively. The minimized dimensions and lower weight of these cranes allow for additional truck configuration possibilities and increased payload, the company stated.
The 40/275 and 50/345 models feature ultra-high tensile steel that provides lower weight, high lift capacity at long reaches and increased payload capabilities. The mounting space required has been reduced to 3 feet 9 inches (1148 millimeters) and 3 feet 11 inches (1198 millimeters), respectively, expanding truck configuration possibilities.
The 40/275 and 50/345 cranes feature a dual power plus link arm system (DL), which is suited for long reaches and lifting in high positions with demanding equipment (such as fly-jib and winch). In addition, the DL system provides precise and regular movements in the entire working. Another feature of the 40/275 and 50/345 models is “over-bending,” which means the working area between the main boom and the outer boom is no less than 195 degrees. Over-bending offers greater flexibility when working through narrow passages and under overhead obstructions, 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 standard on all IMT articulating crane models is the RCL (rated capacity limiter) 5300. The RCL system 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. The RCL 5300 cooperates with the user and compensates when the RCL senses a situation requiring intervention. The system not only monitors safety during crane operation, but also crane position during transport (stabilizers and boom position).
Additional features of the new articulating crane models include:
A radio remote control equipped with an information center that controls stabilizer functions and feedback of loader operation conditions.
Continuous rotation
An internal hose routing system
Optional stabilizer solutions for each side
A flexible stow bracket design that secures boom for transportation but does not allow bracket damage.
Additional features of all IMT articulating cranes include:
A strong hexagonal profile
Load-holding valves on all load-bearing cylinders
An extension system equipped with a regeneration valve to increase working speed
The 40/275 and 50/345 cranes join the other IMT articulating crane models, which are designed to offer a wide range of options in lifting capacity and reach. The IMT articulating crane lineup has a maximum reach ranging from 10 feet 2 inches to 70 feet 10 inches and offers lift capacities ranging from 1,740 pounds (790 kilograms) to 38,185 pounds (17,320 kilograms) maximum rating.
