Title:
INSULATED AERIAL WORK CAR AND AUTOMATIC RANGE LIMITING METHOD FOR INSULATED WORK PLATFORM THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/170982
Kind Code:
A1
Abstract:
Disclosed are an insulated aerial work car and an automatic range limiting method for an insulated work platform thereof. The insulated aerial work car comprises a range limiting device of a work platform. The range limiting device of a work platform comprises: a lower arm inclination angle detection sensor (5); and a lower arm length detection sensor (6), an upper arm range variation detection sensor (7), and an upper arm length detection sensor (8), each comprising an insulated ranging cable and an extension and retraction measurement mechanism for the insulated ranging cable. An extension length of each insulated ranging cable is detected in real time and converted into an actual working range of an insulated work platform. An operator is allowed to take operational actions to increase a working range when the actual working range is less than a set working range maximum, and the operator is prevented from taking any operational actions to increase a working range when the actual working range is greater than or equal to the set working range maximum. Thereby, the present invention guarantees the stability of an entire car, and avoids tipping over of the entire car or damage to arm supports caused by a working range of an insulated work platform being beyond a required working range.
