Ralla
Ralla is a turntable that is adaptable for narrow spaces, where manoeuvering with a vheicle is practically impossibile. Easy to use, it can turn the car through 360° where it has been parked thus facilitating a way out from the narrow space. Completely electronic it can be provided with a remote control. This turntable has been developed in different sizes of diameter and capacities up to 8 meters in diameter and 8 tons capacity.
Description
Ralla 25
è una piattaforma rotante per quegli spazi dove le manovre di movimentazione del veicolo risultano estremamente complesse. Di facile utilizzo, la Ralla 25 può essere installata anche in versione piastrellabile, per cui l’effetto di continuità con il pavimento attiguo ne incrementa le qualità estetiche.
Essentially
the Ralla 25 has eleven main structural elements:
- Four platform wedges
- Four wheel guides embedded in the construction work
- A structure connecting to the underlying circular rack
- Panel covering the connection structure
- Motor assembly
- Four platform wedges
- Four wheel guides embedded in the construction work
- A structure connecting to the underlying circular rack
- Panel covering the connection structure
- Motor assembly
Each of the wedge-shaped
sections of the Ralla 25 has four polyurethane wheels, reducing the amount of unsupported space to the barest minimum and thus preventing deformation of the platform due to uneven weights. This also significantly reduces noise.
The polyurethane wheels
are secured to the structure with mechanical pins, hooked onto a “U”-shaped structure welded to the platform.
Once the four sections
of the platform have been secured to the connection structure, they are closed by a covering panel that ensures a uniform finish.
The central rotation pin
- set on the motor assembly and fit with thrust bearings to completely absorb compression due to weight - is used to accommodate the connection structure.
The gearmotor
is one with the structure supporting the central rotation pin. The gearmotor is built so that it is easy to install and does not allow for coupling errors.
The rotation pinion
is coupled to the turntable’s circular rack by shifting the gearmotor assembly forward and back. This movement is enabled by just two slots located on the side of the assembly itself; moreover, once coupling has been completed, it can be locked in place with two securing bolts.
