Most telehandler overloads do not happen because an operator ignored the load chart. They happen because the chart in the cab was for a different attachment, or because nobody could read it at arm's length with a bucket already in the air.
Halloran's TH42 moves the chart to a screen and makes it specific. Each approved attachment carries an ID chip in its coupler; when it locks on, the machine loads that attachment's capacity envelope and draws the operator's current boom angle and extension as a live dot inside it.
A warning that arrives before the beep
As the dot approaches the edge of the envelope, the extend function slows before it stops, giving a physical cue rather than an alarm that sounds identical to every other alarm. Unrecognised attachments fall back to the most conservative chart the machine holds, which Halloran says is a deliberate nuisance.
The TH42 reaches 12.8 metres and 4,200 kilograms, and ships in the first quarter of 2027. Halloran will publish the chip specification so third-party attachment makers can register their own envelopes.
