Abstract

The invention discloses a manual control and remote control integrated electric fork lift truck, which belongs to the field of electric fork lift truck and comprises an electrically-driven fork lift truck on a working face. The fork lift truck is provided with an operating room; the operating room is provided with a manipulation button which is connected with a control system; and a power supply end of the control system is connected with a power supply cable arranged on the rear part of the fork lift truck. The fork lift truck is characterized in that: the fork lift truck on the working face is provided with a wireless monitoring system and a wireless control system; a terminal operating floor of the wireless monitoring system and the wireless control system are arranged in a work station; and the wireless control system is connected in parallel and mutually locked with the manipulation button in the operating room and then connected with the control system. An operator can monitor the conditions of the working face and control the work of the electric fork lift truck on the terminal operating floor of the work station. When the wireless control system controls the fork lift truck, the manual operation system stops so that the fork lift truck receives only one command; and the fork lift truck operates in a large range and is convenient to control.

Description

technical field [0001] The invention provides a scraper, which belongs to the field of engineering machinery, in particular to an electric scraper integrated with manual manipulation and remote control. Background technique [0002] The empty space left after underground magnetite mining, especially the large empty area with a width of more than 10m and a length of 40m, may have the possibility of "roof fall". The area of ​​"roof fall" and the size of the collapsed rocks cannot be estimated. To ensure the safety of personnel, unmanned electric loaders should be used to fill empty spaces. [0003] Chinese patent (CN200720018164.2) provides a kind of electric forklift, and it has bracket, and bearing and another bearing are respectively installed in the upper and lower bearing sleeve, and sleeve is installed on the inner side of two bearings, and the upper end 56FA of sleeve is fixed with support The upper end of the cable is wound on the runner, the other end of the wire rop...
