The Choker System

Harvesting timber in New Zealand forests is as demanding as anywhere in the world. Our terrain ranges from even flats to steep hillsides, with gullies, waterways and rugged landforms creating challenges.

Our electronic choker has been designed to make a difference to the safety and efficiency of timber recovery between felling and yarding.

It works by giving forestry contractors a remote-release option that allows the operator to be safely separated from the most hazardous part of the recovery process.

With the simple press of a button, the choker releases the strop as soon as the log has been dragged to its required position. This removes a man from a dangerous situation among unstable timber, and leaves the choker ready for the next haul.

System Overview

Specifically designed for harvesting timber in difficult hill country, the choker is used to attach a hauling strop to felled logs, ready to drag them to the yarder for trimming and transportation.

The choker comprises the most advanced engineering in its class. The electronic-release switching mechanism is encased to protect it from impact and weather damage, and ensure its reliability, even the harshest conditions.

The Choker

Fortronics Electronic Chokers are radio-controlled devices. A UHF radio frequency digitally coded signal is used to command a set of chokers. Each choker is identified by a group code number and a choker ID number.

Main Transmitter:

Up to eight chokers can be commanded to release collectively in any combination or individually by simply turning on the appropriate switch and pushing the release button momentarily.

Portable Transmitter: – (two supplied)

Holding the release button down for more than three seconds will release all chokers at once.
