Magni’s RTH 5.39S rotating telescopic handler reaches for the top

Magni TH developed a rotating telescopic model which is among the highest-reaching in the world. The RTH 5.39S is a medium-size chassis and scissors stabilised. The chassis is the same as the RTH 5.30S and has been reinforced to resist the big stress of working at extreme height. The 38.7tonne machine has a maximum lifting capacity of 2tonnes, allowing a reach of up to 13 floors.

RTH 5.395 rotating telescopic model
7308 Magni TH developed a rotating telescopic model which is among the highest-reaching in the world. The RTH 5.39S is a medium-size chassis and scissors stabilised.

The chassis is the same as the RTH 5.30S and has been reinforced to resist the big stress of working at extreme height. The 38.7tonne machine has a maximum lifting capacity of 2tonnes, allowing a reach of up to 13 floors.

The transmission is composed of a Euro 4 final Mercedes Engine with 170kW one 2253 Bosch Rexroth hydrostatic piston pump and a Bosch Rexroth hydrostatic motor.

The hydraulic circuit is load sensing with 350bar operative working pressure and face seal fittings connections and consists of a Bosch Rexroth hydrostatic piston pump and a 7 elements Danfoss distributor with SIL 2 safety standards, with double electronic check of the position and of the direction of the spool.

Another small distributor from Bosch is installed to manage stabilizers.

The patented boom consists of six elements with two cylinders for extension placed outside the boom itself, and inside there are just hoses and pipes. In this way hoses have more available space to move during extension and retraction of the boom and this avoids accidental breaks.
 
Software management is innovative. The first four sections are activated by the cylinder placed on the upper side of the boom and they move proportionally with the chain extension system. The 5th element - the biggest and the heaviest - is managed by another cylinder placed on the lower side of the boom, which works in a proportional way to the boom angle. This means that the more the angle increases the more the 5th element extends.

This extension system has been developed to keep a good load capacity on the wide horizontal reach, otherwise the weight of the 5th element would reduce too much the load capacity of the machine. Things are different in the vertical sense instead since in this case the weight remains close to the load centre of the machine.
