A dense chassis outfitted with a uniform weight distribution profile is a must-have asset when lifting those hard-to-manage 50-tonne loads. The 50T Tadano crane truck (TG-500M) achieves this lofty goal by partnering heavy-duty lifting power with a rugged frame. At its heart, the reinforced telescoping boom is responsible for lifting and moving weighty cargo. This alloy-augmented boom extends from its stored 10.65 Metre length to an impressive 40-Metre span, stretching in segments to steadily transport its load. Smooth conveyance is guaranteed by superior weight management, but four outriggers are also on hand when the load is awkwardly shaped or the work site is uneven.
The 50T Tadano crane truck accentuates lifting muscle, but that doesn’t mean it lacks in other departments. Eight wheels ensure the driving experience is safely managed between construction areas, so this workhorse vehicle will always arrive on time and ready to flex its muscles. In supporting this claim, there are two operator cabs incorporated into the design, dedicated cabs that ensure the operator has the best view of what’s going on at any moment. The front cab controls steering and a series of brake systems, including a safety-centric auxiliary brake system that uses an electro-pneumatic mechanism. Finally, while still on the subject of braking, parking and stability is a huge part of the day-to-day operations of a crane truck. This heavy lifter enhances motionless stability by incorporating a powerful mechanically-operated parking brake into the build, thus anchoring the chassis and wheels in place.
Load charts are needed to evaluate the reach of the 50T Tadano crane truck (Model TG-500M). An expert operator quickly translates the relevant information on the chart into real world data. The boom does indeed mechanically elongate in stages to cover a 10.65 Metre to 40.0 Metre range, but load capacity will, as with any other crane, vary across this length. At 10.65 Metres, a 50 tonne lift is supported, but, once the boom is fully extended, the capacity shrinks to a still respectable 8,000 Kilograms. Of course, this being a fully-loaded vehicle, there are a number of other factors that need to be considered before quoting loading figures. The hydraulically-powered 7.4 Metre long outriggers increase lift efficiency, as does the capable jib section.
The work-proven TG-500M-4 is a versatile mover with heavy duty characteristics. The 5 section extending boom is controlled by the rear cabin. From here, control levers manage fast acting valves to move the boom and jib. Two coils of wire rope are rigged, each one opting for an 18 MM diameter to guarantee a beefy lift profile. Safety is further underscored by the addition of a range limiter, a winch drum lock, and the inclusion of stability counterbalancing valves.
