Detailed Description

Technical Specifications for Multifunctional Transport Vehicles

1、Introduction to intermodal transport vehicles

The multi-functional transfer vehicle is primarily designed for handling containers, energy storage cabinets, and non-standard oversized items during material handling and loading/unloading operations across production process stations. Featuring lifting and unloading capabilities, load-bearing mobility, high-efficiency maneuverability, versatility, and reliable safety, this vehicle can independently complete the transfer, handling, and loading/unloading of heavy containers and energy storage cabinets without requiring additional equipment.

The multi-functional cross-carrying vehicle consists of a chassis, powertrain, hydraulic system, control system, lifting mechanism, steering mechanism, lifting device, and safety/auxiliary functions. Its working principle is as follows: The powertrain (diesel/electric) drives a hydraulic variable pump to provide hydraulic power for all hydraulic motors and cylinders, enabling the vehicle's movement, steering, and lifting operations. During operation, the operator either drives the vehicle manually or uses a remote control. The vehicle travels along the container's length until it reaches the top, where the lifting device is secured to the container by either an automated system or manual installation. Subsequently, the vehicle's lifting, moving, and turning functions are controlled to facilitate loading/unloading and transshipment of containers.

6、Introduction to the main performance features

Product features:

Ø Compact structure with robust performance: The load-bearing structure meets Q355 steel strength standards, while the entire vehicle undergoes ANSYS finite element analysis for optimization.

Ø The hydraulic system is mature and easy to maintain, with imported hydraulic components and an optimized hydraulic system.

Ø Compact and maneuverable: The vehicle features a compact design with four-wheel steering, enabling a narrow turning radius. This makes it ideal for indoor factory operations without requiring AGV assistance.

Ø High safety performance: The system features lifting and pulling safety anti-fall locking, load adjustment, audio-visual warnings, outline lights, dangerous action locking, and protective devices. Additionally, it employs remote control operation, ensuring operator safety when working at a distance from heavy objects.

Ø Smart Control: The remote control is easy to operate, and the vehicle display shows real-time status, including operation, steering, and lifting data. A single button allows you to check vehicle faults instantly.

The main components of the transshipment vehicle are frame, powertrain, hydraulic system, control system, lifting mechanism, steering mechanism, lifting device and other safety and auxiliary functions.
1. The main body of the vehicle frame
act on	It is used to fix the parts and keep them in the right relative position, and to bear the static and dynamic loads from the car and the ground.
Performance Introduction	Ø The manufacturing material of the main load-bearing component must match the performance of Q355 steel, and the equipment's mobile load should withstand a 10% overload. Ø The steel is cut by CNC, and the weld is polished smoothly without sharp cuts. Ø All bolts and nuts are threaded to the metric 10.9 standard and comply with ISO specifications. Both bolts and nuts are equipped with anti-loosening or anti-disengagement measures. Ø The buffer rubber is arranged at the contact position between the rack and the container. Ø The steel surface must undergo sandblasting or shot blasting prior to painting. The minimum degreasing and rust removal grade is Sa2.5, with manual rust removal applied to localized blind spots at a minimum grade of St2.5.

Performance Introduction	Ø The valve group sensitive proportional valve ensures precise control. Ø Hydraulic cylinder features reliable performance, built-in magnetic scale, and imported oil seals. Ø The pipe joint is clamped and fixed on the frame to withstand vibration and impact. Ø The design of the hydraulic oil tank is convenient for cleaning, the filter element is easy to replace, and the oil level gauge is easy to observe. Ø The hose length at the lifting section is moderate and is secured and protected by a tank chain or other means to ensure that it does not get blocked or damaged by bending or external forces during operation. Ø The hydraulic system of the lifting mechanism has the ability of self-locking.
4. Control System
act on	The vehicle control is realized by controlling the valve group of the hydraulic system.
Performance Introduction	Ø The car computer control has simple control logic and convenient maintenance. Ø The anti-interference measures and electrical isolation measures in the design of control cabinet can avoid magnetic field interference. Ø The door of the electrical control cabinet is equipped with a button spring lock for easy maintenance. The edges and corners of the cabinet are sealed to prevent dust from entering and accumulating inside. Ø The emergency stop button can cut off all power sources as an emergency trigger.
5. Lifting mechanism, walking and steering mechanism
act on	Monitoring and Execution of Lifting, Pulling, Moving and Turning Actions of Cross-transport Vehicle
Performance Introduction	Ø The running adopts the static pressure transmission, the reducer and the hydraulic motor are placed in the drive wheel, which is safe and reliable. Ø The steering mode can be realized by the steering mode of straight line with reverse gear, small angle slant, front wheel steering and rear wheel steering. Ø The walking speed can be adjusted freely. Ø The lifting hydraulic cylinder is equipped with a hydraulic lock (balance valve), so that the hydraulic cylinder will not slide down even if the external pipeline bursts.
6. Safety and Auxiliary Features
act on	Improving the Vehicle Safety Performance and Operation Convenience
Performance Introduction	Interlock function: The lifting system is not allowed to operate when the vehicle is turning. Self-locking mechanism: In case of pipeline leakage or rupture, the hydraulic system automatically locks to prevent load collapse. The limit of the turning cylinder is set to the lifting and turning, etc. When the limit is reached, the pressure will be released if the oil is supplied. Height limit: there are mechanical limit and soft limit. Two-speed: Features high and low speed settings. Warning and lighting lights: anti-vibration lighting lights and warning lights are installed on the side of the vehicle frame. Safety signage and protection: All signs, cables, and pipelines are installed in iron conduits or steel clamps, with protective sleeves on oil pipes to ensure overall aesthetics.
