Portable Traffic Light Signal Unit (PTSU)

Portable Traffic Light Signal Unit (PTSU)

Portable Traffic Light Signal UnitThe PTL portable traffic light signal system has been designed as a safer alternative to STOP/SLOW signs. The product is intended for traffic control around roadworks or other construction sites and is easy to set-up and operate with minimal training.

The Portable Traffic Light system can use one or two PTSUs, controlled by the Hand-held Remote Controller (HRC). Each PTSU is built to withstand the rigors of a harsh outdoor environment and has been ergonomically  designed for operator set up and dismantling.

Each individual Portable Traffic Signal Unit (PTSU) has sensors to detect excessive heat, rotation, tilt or excess movement using accelerometers, an electronic compass and GPS. The intelligent firmware has multiple safety interlocks based around critical alerts to turn the signal to red in the event of operational problems such as; loss of communication, lantern LED failure, power supply and many others.

Mounting of the lantern head is at waist height, minimising the risk of operator back strain and pinch points.

Key features:

  • Lightweight design for easy set-up
  • Highly stable tripod base, fabricated from zinc plated steel
  • Built in alarms: tilt, GPS, compass rotation
  • Robust adjustable tripod to enhance stability in any terrain
  • Hot-swappable 20Ah 12V LiFePO4 battery power supplies
  • Quick fit target board for higher visibility
  • Designed and manufactured in Australia

PTSU Major Components

Tripod

The tripod is fabricated from zinc plated steel with a X15 orange powder coated finish. The length of each leg is adjustable so that it can be made stable on most terrains. There are feet at the end of each leg to aid stability and enable the application of ballast if required. The tripod stem is adjustable in height.

Lantern Head

The lantern head is made of poly-carbonate plastic.  It is attached to a metal pole that fits on to the central stem of the tripod. The lantern housing is rated at IP 33 so wherever possible it should not be left in a horizontal position without a water-resistant cover.

The LED lights are low profile with an IP 65 enclosure rating. These fully sealed modules are easily replaceable in the event of faults.

The lantern casing houses sealed units which contain communication equipment and controllers for the LEDs. The lantern head also houses the radio antenna,  the GPS antenna and the rear facing visual indicator yellow flashing light showing LED on red.

Removable Battery Pack

The removable battery pack contains a 12V rechargeable lithium iron phosphate battery.  It is locked on to the PTSU when in use, with the enclosure removed for recharging and transporting (Battery charger also supplied).

The battery enclosure is permanently locked to avoid tampering.

Hand-held Remote Controller

The Hand-held Remote Controller (HRC) is the device that controls the Portable Traffic Signal System (PTSS).  It communicates with the PTSU’s using radio communications on the unlicensed 915 MHz spectrum.

The HRC acts as the master and notifies the user of any faults or issues, such as a moved PTSU. The HRC is rechargeable and has a USB data connection cable for charging and log file download.
