What is the reason for the tilt alarm and inability to move in an articulated boom lift?
2 Answers
The tilt alarm in an articulated boom lift is caused by cable circuit faults, level sensor malfunctions, or circuit board issues. Below is a related introduction to articulated boom lifts: Self-propelled articulated boom lifts: Self-propelled models can move automatically via handles or other buttons. This type of articulated boom lift is classified as construction machinery equipment and does not fall under the category of special equipment, thus no certification is required for operation. Vehicle-mounted articulated boom lifts: Vehicle-mounted models have lifting equipment installed on the vehicle. This type is classified as special equipment, therefore special certification is mandatory for operation and use; otherwise, operation is not permitted.
I've dealt with many cases of articulated boom lifts triggering tilt alarms and becoming immobile. Generally, this occurs when the safety system activates its protection mechanism - automatically sounding an alarm and stopping movement when excessive vehicle tilt is detected. There are multiple potential causes: the inclination sensor may be damaged (incorrectly perceiving the vehicle angle and triggering alarms), hydraulic system failure (insufficient pressure leading to travel function lockout), or uneven ground surfaces activating the system. Recommended first step: check whether the parking surface is level - if on a slope, move to gentler terrain. If alarms persist, immediately seek professional maintenance to inspect sensors and control systems. Never attempt forced movement to prevent rollover accidents. Regular maintenance significantly reduces such issues, ensuring worksite safety and extending equipment lifespan while minimizing operational disruptions.
