  • the lifting system 7 of the type described above allows the position of the engine compartment 15 to be varied depending on the specific conditions of use of the radio-controlled vehicle 1. For example, it allows the engine compartment 15 to be lifted from a lowered position very close to the supporting plane nl, so that the radio-controlled vehicle 1 can be moved forward even on an incline and/or on rough terrain .
  • the li fting system 7 can be useful for counterbalancing a load applied to the tool T by moving the engine compartment 15 in order to change the position of the centre of gravity of the radio-controlled vehicle 1 .

  • the fact that the li fting system 7 comprises two actuators 18 aligned on a plane n2 inclined relative to the longitudinal axis X of the radiocontrolled vehicle 1 reduces the risks of any bending of the actuators 18 ( in particular, it reduces the risks of bending under buckling load) .
  • an actuator 18 has an outer liner 38 fitted onto an inner liner 40 allows the engine compartment 15 to be precisely centred on the fixed portion 5 of the frame 2 .
  • the presence of a sealing system 41 between the outer liner 38 and the inner liner 40 makes it possible to elastically compensate for any misalignments and inclinations .
  • each hydraulic cylinder 19 is a double-acting cylinder with the closing chamber V2 located below the opening chamber VI relative to the piston 22 allows the descent of the engine compartment 15 to be cushioned during the closing operation and reduces the risk of the engine compartment 15 falling precipitously downwards under the action of its own weight .
