Abstract

The invention discloses a heavy forklift sharp turn safety control system and method. According to the method, when it is judged that the speed of a vehicle is greater than or equal to a preset value,it is indicated that the whole vehicle runs at a high speed; if the steering angle change rate of a steering wheel is greater than or equal to a preset value, it is indicated that the vehicle is in asharp turn state currently; the steering angle of a rear axle is limited at a preset angle limit value; the speed of the vehicle is limited at the preset value; and braking force is gradually increased to realize slow braking.

Description

technical field

[0001] The invention relates to a safety control system for sharp turns of heavy-duty forklifts, and also relates to a safety control method for sharp turns of heavy-duty forklifts based on the system, which belongs to the technical field of safety control equipment for heavy-duty forklifts. Background technique

[0002] The terms involved in the present invention are explained as follows:

[0003] Heavy-duty forklift: A forklift used to fork heavy goods, usually a forklift with a rated forklift capacity of 4.5 tons or more is defined as a heavy-duty forklift.

[0004] Steering wheel steering angle change rate: The initial steering angle of the steering wheel within a period of time is calculated as a difference, which is used to describe the variable of the speed of the steering wheel steering angle change.

[0005] Heavy-duty forklifts generally have narrow operating sites and high operating intensity, which requires the vehicle to have flexible turning an...
