Ralla

The Ralla parking turntable is the ideal choice for installation in very narrow urban spaces, where manoeuvring a vehicle for parking would be extremely difficult, if not impossible. This easy-to-use turntable can completely turn vehicles through 360°, offering an easy exit from narrow spaces.

Completely electronic, Ralla can also be fitted with an optional remote control. The Ralla turntable has been developed in sizes up to 8 metres in diameter, and with capacities up to 8 tons.

Ralla can also be supplied in a tiled version to match the surrounding floor area, for an even more attractive parking solution.

The Ralla features 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

Each of the wedge-shaped sections of the Ralla features four polyurethane wheels, minimising the amount of unsupported area and preventing deformation of the platform due to unevenly distributed weight. This clever system 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.

The connection structure is a cross-shaped element welded on the top.

Once the four sections of the platform have been secured to the connection structure, they are closed by a covering panel, ensuring a uniform finish.

The pit edging profile also serves as a track for the wheels, preventing the wear that would come from running on rough concrete. Each part of the edge has a flange for securing to the next part, creating a solid guide structure. Moreover, some iron consolidation pieces are welded on the back of the guide to ensure that the unit is solidly secured to the concrete.

One of the four sections has a hatch for maintenance and inspection of the motor.

The connection structure is snapped into the central rotation pin in the underlying area.

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.

Easy to install, the gearmotor is one with the structure supporting the central rotation pin, removing the possibility of 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. Once coupling has been completed, it can be locked in place with two securing bolts.

The pushbutton control panel features buttons to control clockwise and counter-clockwise rotation, along with an emergency button and safety key.
