Description
Technical Field
[0001] This utility model relates to the field of construction transportation equipment technology, specifically to a portable heavy object transport vehicle for construction sites. Background Technology
[0002] Material handling is a common need during construction, especially when moving heavy objects such as structural steel, steel pipes, and solid wood, which are large and bulky. Traditionally, this involves using on-site cranes in conjunction with manual labor. However, large cranes are difficult to operate indoors or in confined spaces, forcing many handling tasks to be completed entirely by hand. This not only results in low efficiency (each person can handle less than 2 tons per day) but also poses serious safety hazards such as injuries from falling objects and crushing injuries. Furthermore, the prolonged occupation of tower cranes and other equipment significantly impacts the overall construction progress.
[0003] Currently, the industry lacks specialized heavy-duty transport tools, forcing construction companies to alleviate the problem by increasing manpower and extending the construction period. While temporarily using forklifts and other equipment can partially replace manual labor, it is still limited by complex electrical wiring and poor spatial adaptability. Especially for short-distance transport of objects weighing less than 5 tons, it is impossible to fully utilize the efficiency of large equipment, and it is difficult to avoid the high risks and low efficiency of manual handling, forming a long-standing technical pain point that plagues construction safety and cost control.

[0049] In operation, the operator starts the generator 1-2 of the integrated power control platform, and activates the hydraulic pump station 1-3 and the travel motor 3-2 through the integrated control box 1-4. The telescopic frame 2-2 of the combined cargo vehicle body 2 is extended to 6 meters, and 4 tons of steel pipes are loaded into the cargo hopper 2-1. The pressure sensor 3-4 monitors the load data in real time. The hydraulic cylinder 3-1 raises the guide head 2-3 to level the vehicle body. The operator operates the travel button on the control box, and the travel motor 3-2 drives the moving load-bearing steel wheels 3-3 to transport the heavy load at a corresponding speed. When encountering a 5-degree slope, the hydraulic system automatically compensates for the balance. After reaching the target location, the hydraulic cylinder lowers the vehicle body to unload the cargo. No external power supply or auxiliary equipment is required throughout the entire process.
