Lift and separate

  • Comment
Rising cars, rising barriers and rising damp are just a few examples of applications of recent technological advances

Parking dimensions for manoeuvring a vehicle in a car park are always larger than most architects would like.

For 90infinity entry parking, the 4.8m x 2.4m standard bay (although Neufert recommends 5m x 2.3m) has to be accompanied by at least a 5.5m wide roadway turning circle.

Bays for disabled drivers often need an additional 1,200mm width, depending on the layout of the bay. It all goes to show that parking takes up valuable space.

The current method of addressing the problem is to curtail the use of cars and so reduce the pressure on parking spaces. Getting rid of the car isn't necessarily the most magnanimous gesture, although it certainly saves tarmacadam, but an innovation from Israel could provide the best of both worlds.

The 2-Park system is a new-generation car lift. The loading/turning circle and bay size are almost the same as in a conventional park layout, but the system can accommodate twice the number of cars.

Cars parking on ground level enter under the steel framework and park in the normal manner. The 2-Park system's structural framework leaves door openings unimpeded so the ground parking bay is used in much the normal way, although, usefully, cars can no longer straddle the white lines of adjoining bays.

The driver of the second car calls the upper platform down. Within a minute, the silent hydraulic arms, operated by a 400V, 50Hz, 3HP electric three-phase motor, have descended to ground level to allow the second car to drive on and be hoisted into position above the first.

Care must be taken to allow sufficient clearance between the platform and the ceiling. Even though a clearance of 3.3m is recommended, high-visibility notices should warn drivers of sports utility vehicles (the lift can only take loads of 1,750kg), customised vehicles or those with aerials, of the height restrictions.

The ground-floor vehicle can be moved without disturbing the uppermost vehicle. When the second car comes down, the process is reversed.

At ground level, the turntable function rotates the vehicle through 90infinity, 180infinity or 270infinity to minimise the rollon/roll-off turning head.

While weighing in at 1,250kg and imposing double car loads on any supporting structure, the 2-Park system is still a useful space saving concept.

Intelligent traffic control

Nortech's new French-made intelligent car barrier control system minimises the installation of underground loops and eliminates the possibility of external interference.

Using 2.45GHz microwave technology, it moves away from the conventional lower frequency ranges, so avoiding the chances of interference with other radio signals.

The new Hyper X system operates by reading a tag on the windscreen of the car (and can read the card even if it is placed horizontal to the reader - lying on the dashboard for example). Tag batteries last for up to seven years and the aerial reading the data is located in the centre of the barrier arm.

Based on research and development in the aerospace industry, it is certainly a cut above most other providers of barrier systems .So much so that its longdistance reading qualities can identify the tag of a vehicle travelling at up to 120mph.Presumably, Hollywood car chases would have looked very different with this type of barrier around.

Dispensing with damp

An ingenious solution to rising damp has been developed in France, which relies on the premise that electrical engineering is generally repulsive. In this instance, the Fraal Dry Tech electric unit eliminates water and electrochemical phenomena that can cause rising damp in walls.

The unit comprises a small 10W control box and two electrodes wired up to holes drilled in the wall.

This generates an electrical current that spreads in the wall and 'pushes' the moisture toward the ground.The movement of ions caused by the applied electrical field, together with the movement of water, carries particles and micelles (which reduce the surface tension of a liquid) that gradually block capillary pathways.

Fraal is seeking trade partners to import and distribute its products.
