BAUMA LAUNCH FOR LATEST CONJET WIRELESS CONTROL UNIT

2004-03-05 — Conjet AB will use Bauma 2004 for the world launch of the wireless control unit for its industry leading Conjet Robot 322 and Conjet Robot 432D hydrodemolition machines, which use a very high pressure water jet to remove concrete from numerous structures, including tunnel and hydro-electric turbine linings, bridge decks, joints, soffits, pillars and columns, harbour and dock walls, dam faces, car parking decks and airport runways.

The wireless control unit, on display in Hall A1 stand 225, has the advantage of allowing the Robot operator to move freely without being obstructed by a normal control cable. The unit has been designed to provide enough reach for all possible hydrodemolition applications. If the robot loses contact with the remote wireless control unit the emergency stop is automatically activated and the robot and the pump will shut down.

The remote wireless control unit is powered by standard mobile phone batteries. The charger, which is supplied with the wireless unit, can be powered from the mains supply or from the 12-24 Volt DC outlet on the robot. There are currently two versions of the radio control unit to cater for the different radio transmitting regulations in the European and American markets. The wireless control unit is available as a retro fit option for the Conjet 322 and Conjet 432D and is very easy to install. The receiver/transmitter is placed under the Robot’s cover and connected to the machine’s standard remote control socket and the unit is ready for operation in seconds.

In addition to the wireless control unit Conjet will also use Bauma 2004 to display its latest Conjet Robot 363 MPA with multi-positioning arm and Conjet Robot 322 hydrodemolition machines. The larger Conjet Robot 363 MPA is a compact, exceptionally manoeuvrable, self contained, four-wheeled hydrostatically driven concrete removing hydrodemolition Robot with a multi-positioning arm (MPA). The arm is mounted on a 360º rotating turntable on the front of the base carrier to provide a reach of over 6m. The versatile MPA gives the operator considerable flexibility to use the Conjet Robot 363 MPA on a wide variety of hydrodemolition tasks, including reaching up into tunnel crowns or under a bridge deck soffit while the machine stays on the deck above.

The Conjet Robot 363 MPA is complemented by the Conjet Robot 322, a remotely operated hydrodemolition robot, which is compact, light, exceptionally manoeuvrable and ideal for working in confined spaces and areas inaccessible to larger equipment. It is very narrow and can pass through a 0.8m to 1m wide opening, depending on attachment tool, making the Robot 322 ideal for operating in tunnels as small as 1.7m diameter with rotor attachment, culverts, inside concrete box girder bridge decks and under bridge and quay decks. The Robot 322 is also exceptionally efficient for use in numerous industrial-cleaning applications and has been designed to operate with existing 134hp to 470hp (100kW to 350kW) diesel driven high-pressure pumps feeding water to the jetting nozzle.

The Robot 322 is easily adaptable to take a variety of hydrodemolition tools. It also enables hydrodemolition contractors to mechanise and replace the far less efficient and less productive hand lancing and jack hammering techniques. Hand held methods are known to be exceptionally tiring, stressful, noisy, and dangerous for operators. Removal of concrete with a jackhammer or hand lance is also much slower than and not as selective as a Robot. In addition hand lances are very inefficient with their use of water and need far greater quantities than more effective and environmentally friendly Robots to remove a specific amount of concrete.
