AI Technical Summary

Technical Problem

Aerial work platforms face risks of operator injury from obstacles and communication difficulties, especially at significant heights, and existing safety solutions and communication methods are inadequate when the operator is obstructed.

Method used

A gondola with a pressure-sensitive anti-crushing safety device that controls platform movement and communication channel opening based on pressure thresholds, allowing safe operation and communication even when the operator is obstructed.

Benefits of technology

Ensures operator safety by preventing platform movement and enabling communication when obstructed, simplifying design and use by integrating safety and communication controls.

Abstract

The invention relates to a bucket (1) comprising: - a platform (7) equipped with a control console; - a system (2) for moving the platform (7); - a member for activating / deactivating at least one control (4) of the system (2) for moving the platform (7); - a control unit (5); - a communication device (6) managing a closable two-way communication channel between two transceivers (61, 62), one (61) of which is arranged on the platform (7); and - a pressure-sensitive anti-crushing safety device positioned in front of the control console (3). The control unit (5) is configured to control the opening and closing of the communication channel and to prevent the system (2) for moving the platform (7) from being controlled from the platform (7) when the duration and / or the value of the pressure exerted on the safety device are / is greater than a first threshold value. The control unit (5) is configured to control, for each active or inactive state of the activating / deactivating member, the opening of the communication channel (63) at least according to the pressure exerted on the safety device.
