New wireless control technologies are being adopted by manufacturers and users of cranes and other lifting equipment.
Most of us find it odd to look back five or ten years to when our home computers were tethered to the wall by a cable. Somehow we just accepted that the cable restricted the mobility of the device and lived with that limitation. Now, of course, it is completely normal to pull a mobile phone out of your pocket and dial up the internet so that we can look up obscure information, book tickets or connect with a computer many miles away.
In the industrial and commercial arenas, wireless technology has revolutionised many practices. Logistics companies now routinely track the progress of every single parcel in their charge; field engineers collect data from and send instructions to remote facilities such as water pumping stations; customer accounts can be updated in real time, etc.
