| A new Hydrodemolition robot  Aquajet Systems has launched the Evolution control system for its Hydrodemolition robots giving a 20% improved removal rate. The new units features the state of the art on-board Evolution Control System and the new Smart Lance Control system for maximum removal capabilities. Like other robots in the Aquajet range, the new HVD Evolution and HVE Evolution models are versatile machines that are ideal for working on bridges, tunnels, roads, walls, parking garages or overhead roofs. Working with a typically 1000 bar pressure and 250 l/min, the robot handles removal depths down to approximately 1000 mm of concrete if required.The Aquajet Evolution robots are equipped with the new Evolution Control System. This on board computer system together with the Equal Distance System (EDS) provides a 15 to 20 % increase in removal capacity. Built to operate in tough conditions, the system has been designed with the operator in mind and is easy to operate. The Evolution has a built-in operator’s manual in six languages and detailed operator support in plain languages directly on the display. The operator is able to receive immediate feedback on current production data, such as the actual removed area. The Evolution Control System continuously monitors all vital machine systems and functions. It also proves a warning if parameter settings are outside the machines capabilities. The new Smart Lance Control ensures more consistent quality of work, easily controlled by the operator. In the computerised Smart Lance System the operator only feeds in only a few key parameters, such as work width, lance angle, lance speed, and depth. It also automatically adjusts a number of underlying parameters for optimum results, such as work pattern. The Smart Lance Control also compensates for fluctuating operational parameters caused by ambient temperature changes. The system also allows the possibility to programme different widths and depths in the same overpass. The new Aquajet Evolution robots are equipped with the patented EDS, Equal Distance System. Regardless of the set lance attach angle, the system controls and maintains the nozzles distance from the concrete surface. Maintaining an optimum distance, EDS ensures that no power is lost due to the nozzle being too far from the surface. Controlled from an electronic display on the machine, the lance attack angle can be set from –45° to +45º allowing for efficient removal of concrete under rebars. The new robot features an expanded reach, to provide a more efficient working area and more precise removal in corners and along edges etc. This feature minimises manual removal. The versatility of the new robot is further enhanced by the increased possibility to adjust the powerhead sideways. The powerhead is adjustable sideways, totally between 1 to 4 m without moving the crawler-chassis. The side-shift of the power head can be increased to 1900 mm. Total length of the unit varies between 2500 and 2750 mm. Minimum height is 1600 mm with a standard operating height of 6000 mm. The variable-width chassis provides maximum stability during set up and operation. The low centre of gravity in the chassis further enhances the stability. In its narrow version, access to the tightest passages; doorways, alleys, footbridges, is achieved. The track width varies between the narrow versions´ 1030 mm to 1510 in the wide version. The weight of the unit is 1900 kg for the HVE electrically driven version and 2000 kg for the HVD diesel driven version. The robot is available with either diesel or electric drive. It is powered by a 12 kW diesel engine (HVD) or with an 11.5 kW electric motor (HVE). The diesel-driven version can be equipped with an engine brand specified by the customer. The robot features a new radio controlled remote system for increased safety and operator environment. The operator can move around the machine during operation and set-up, whilst maintaining control of the machine. There is also no cable to run over. For environments where radio control is not feasible, remote hardwiring control is also included. write your comments about the article :: © 2005 Construction News :: home page |
