Description

Technical Field

[0001] The utility model relates to the technical field of lift trucks, in particular to a bidirectional rail-changing walking lift truck. Background Art

[0002] The bidirectional rail-changing walking lift truck is an advanced industrial equipment designed for operation scenarios that require flexible movement and height adjustment. This equipment integrates a bidirectional rail system and a lifting platform, and can move freely in the horizontal and vertical directions to adapt to various complex working environments, such as narrow passages and changing terrains. The bidirectional rail design of the lift truck enables it to quickly switch between different rails to achieve multi-directional movement, greatly improving the flexibility and efficiency of operations. The height of the lifting mechanism can be precisely adjusted according to requirements, making it perform excellently in high-altitude operations, cargo handling, and equipment maintenance. Through an intelligent control system, the lift truck can achieve automated operation and path planning, reducing the dependence on manual labor while improving the safety and precision of operations.
