A telehandler operator is using a personnel work platform attachment to elevate workers. During operation, the platform suddenly becomes unresponsive to the tilt controls from the basket, although boom lift and extend functions from the basket work. What is the most likely cause?

Question: A telehandler operator is using a personnel work platform attachment to elevate workers. During operation, the platform suddenly becomes unresponsive to the tilt controls from the basket, although boom lift and extend functions from the basket work. What is the most likely cause?

Answer options: ✅ A lockout switch for platform tilt has been activated at the ground controls.

• The telehandler's main engine has lost power.
• The platform's hydraulic motor has seized.
• The telehandler's steering system has failed.

Correct answer: A lockout switch for platform tilt has been activated at the ground controls.

Explanation: Personnel work platforms often have safety interlocks and lockout switches, particularly for functions like tilt, that can be controlled or overridden from the ground. If other functions are working, a specific lockout for tilt is highly probable. Engine power loss would disable all functions, and steering failure or a seized hydraulic motor are less likely given the specific symptom of only tilt being unresponsive.
