Document Type and Number:
WIPO Patent Application WO/2021/031324
Kind Code:
A1
Abstract:
Disclosed is a calling system for a traction-type building construction hoist, the system comprising a calling device (1) and a prompt device (2). The calling device (1) is in signal connection with the prompt device (2), and the calling device (1) is used for an operator to input calling information and can send the calling information to the prompt device (2); the prompt device (2) is used for receiving the calling information transmitted by the calling device (1) and prompting a driver; and the independently arranged calling system is used for calling a cage (6) of the traction-type building construction hoist. Firstly, the calling device (1) and the prompt device (2) are in direct signal connection, circuit arrangement is quite simple, and maintenance and inspection are facilitated. Secondly, the calling device (1) does not directly control the cage (6) to move up and down, but sends information to the prompt device (2), and prompts the driver by means of the prompt device (2), thereby endowing the driver with a higher control right, and the complex environment of a construction site can be flexibly handled.
