Putzmeister America Introduces "Frequency Hopping" Radio Remote Technology on Its Concrete Pumps and Conveyors
Putzmeister America Introduces "Frequency Hopping" Radio Remote Technology on Its Concrete Pumps and ConveyorsPutzmeister America introduces "frequency-hopping" radio remote controls to virtually eliminate interference when operating its concrete boom pumps and conveyors. Developed in conjunction with HBC-radiomatic, this new and highly unique system is an exclusive to Putzmeister within the concrete placing industry.
In today's wireless world, interference often occurs because an outside source sends a constant signal on the same frequency of a radio remote control. With the recently developed system, a continuous signal is sent between the transmitter and receiver on the truck and "automatically" hops every 60 milliseconds and never shuts down. This ensures the strongest, clearest signal is continually sent without ever losing contact. Also, the operator doesn't need to turn a dial to change frequencies and risk losing a signal.
With each system having its own frequency table, the radio transmits commands through a series of 127 different frequencies - more than double that of competitive versions. Plus, it uses only one frequency for a short period of time as it continually hops to avoid interference.
The unique design features a 200mW to 1 watt output power, again double that of other systems. Plus, it operates on the more powerful 900 Mhz frequency band to cover farther distances. Therefore, the operator can better position himself to accommodate his view of placing concrete versus his distance from the transmitter.
Throughout 2002, the new system will be phased in as a standard feature on the company's core line of concrete boom pumps up to 58-Meters and its Telebelt conveyors at 80-, 105- and 130-foot reaches.
