Description

Technical Field

[0001] The present invention relates to the field of handling equipment, and in particular to a module integrating multiple powertrains and steering systems, and handling equipment. Background Art

[0002] Electric pallet trucks are an indispensable component of modern, efficient cargo handling and are commonly found in warehouses, factories, and docks. They primarily consist of a main frame with fork legs, a drive train that propels the vehicle, a hydraulic system for lifting cargo, a hydraulic cylinder, and a steering control system (handlebars and control handles). Most commercially available pallet trucks, as described in patents CN209938657U and CN211255144U, have the hydraulic system and battery mounted on the main frame. With the increasing use of electric pallet trucks in diverse industries and scenarios, there is a growing demand for more flexible performance configurations. Due to the diverse pallet sizes (container pallets are very narrow), varying cargo types, and environmental requirements, electric pallet truck manufacturers must adjust the main frame and fork dimensions, cylinder and hydraulic system parameters, drive train parameters, and battery parameters to meet these requirements. Existing standard models on the market face these challenges, requiring a complete redesign of the vehicle architecture and reliability testing of the new structure. This results in high management costs, low production efficiency, high losses, and long production cycles. Aiming at the pain points of existing vehicle models, the present invention provides a module integrating multiple powertrains and steering systems for use on electric transport trucks, and transport equipment thereof.
