Lateral or Linear at the Touch of a Button

Jetting Systems Ltd

Why choose when you can have both at no additional cost?

Today there are two competing designs.

The Lateral oscillating head design and the more basic linear design.

The Lateral system has several distinct advantages over the linear system.

Higher Production Rates

In real time operation the lateral system will outperform the linear system for several reasons.

Runway Rubber Removal Lateral

 

The Osprey lateral system covers a removal path of 2100mm and has a typical rubber removal rate of between 600 and 800 sq Mt per hour. The comparatively slow forward speed ensures that the operator is easily able to maintain directional control and a minimal lateral overlap. The CNC control ensures automatically a minimal transverse overlap of no more than 5mm is achieved, thereby ensuring minimal wasted overlap time.

As is normally the case airport operations will allocate smaller blocks for rubber removal applications and so a wider removal width is more appropriate as then fewer unproductive turns are required.

As an example a 100 mt  X 16 mt wide area will require only 8 passes with the Osprey Lateral head whereas with the smaller 700 mm Linear system a staggering 22 passes will be required. Each pass of course includes a time wasting turn.

The narrower removal path when in Linear mode does however have advantages where on rare occasions long interrupted runs are available or for the removal of line markings.

The head may move to cover 2100 mm or remain static anywhere within the frame. This is a feature that is not available with more basic Linear machines on the market. With the Osprey both lateral and linear options have always been available at the touch of a button. 

BEWARE OF CLAIMS OF HIGH PRODUCTION RATES WHICH WILL NOT BE ACHIEVED IN REAL TIME OPERATION.

Runway Rubber Removal Linear

A linear machine with a head diameter of 700 mm would have to travel at 1kph in order to match the rubber removal rate achieved by the Osprey. Some manufacturers claim removal rates of 1600 sq mt per hour this would mean a forward speed of 2.3 kph. Effective rubber removal is not possible at such a forward speed.

Friction Grooves

When in lateral mode rubber removal from the bottom of friction grooves is particularly effective as the water jets are directed to the bottom of the groove.

Rubber removal from the bottom of friction grooves is not as effective when in linear mode.

The Osprey’s rubber removal robot is mounted on the front of the chassis and does not obscure the lights when stowed. It is ready for operation in seconds and can be raised whilst evacuating the runway at full road speed.

Versatile

Whilst extensive testing has proven that the lateral method of rubber removal provides superior results and higher production rates there are occasions where a fixed rotating head can prove beneficial.

With the Osprey you can have this extra versatility at no additional cost. This is a feature not available on the more basic Linear machines.
