The "heavy-duty, flexible hero" of machining workshops—a 25-ton Trackless Flat Car—enables smooth handling of large work-pieces


In machining workshops, heavy machine tool beds, large die-casting molds, and core components of construction machinery, often weighing over ten tons, are the "core" of production, yet they also present a "challenge" in handling. Traditional forklifts lack the load capacity and stumble around corners; rail-mounted flatcars are constrained by their tracks, making them difficult to move even with slight changes to the workshop layout.

Product Introduction

In machining workshops, heavy machine tool beds, large die-casting molds, and core components of construction machinery, often weighing over ten tons, are the "core" of production, yet they also present a "challenge" in handling. Traditional forklifts lack the load capacity and stumble around corners; rail-mounted flatcars are constrained by their tracks, making them difficult to move even with slight changes to the workshop layout.

Technical Parameters:

Load Capacity

25 t (can stably carry heavy machine tool beds, large molds

 and other work-pieces)

Table Size4000 mm*2500 mm* 550 mm
Wheel

Ultra-high molecular weight polymer 

wheels *4 pcs

Travel Speed

0 - 30 m/min (adjustable frequency conversion, 

low and stable speed when heavy load, 

speed can be increased when no load)

Operated Mode

PLC intelligent control, support for wireless remote control 

(effective operating distance ≥ 50 m, convenient 

for cross-station control) + manual emergency operation

Climbing Ability

≤5% (to cope with slight slopes on the workshop floor to 

ensure smooth transportation)

A 25-ton trackless flatcar with a load capacity of 2.5 x 4 meters and a load surface area of ​​2.5 x 4 meters is the key to solving these pain points. 

1. Optimized Load-Bearing Capacity, Precisely Matching Large Work-pieces
With a rated load of 25 tons, it easily lifts core work-pieces such as heavy machine tool beds (typically 15-22 tons) and large marine engine blocks (approximately 20 tons). Its generous 2.5 x 4 meter load surface perfectly adapts to workpiece size and shape—whether it's long steel bars or irregular molds, it can stably carry them, eliminating the risk of tipping during lifting and transfer.
2. Trackless Freedom, Adapting to Workshop Layouts
Free from the constraints of tracks, trackless flatbed carts are like "flexible giants" that navigate the complex layouts of machining centers.
In equipment-intensive areas, the intelligent steering system enables tight right-angle turns, allowing precise passage between clusters of machine tools.
In temporary material storage areas, the cart's route can be flexibly adjusted, eliminating the need for long detours required by tracked flatbed carts. This reduces the distance traveled from processing point A to processing point B by 30%. 3. Prioritizing Stability to Protect Processing Precision
Machining places stringent demands on the integrity of work-pieces; even the slightest bump can affect subsequent precision. The trackless flat car is equipped with a precise speed control system and a stable suspension device:
Starting and stopping are as gentle as still water, preventing work-piece deformation due to inertial impact.
During operation, the wheels maintain stable contact with the ground, keeping horizontal work-piece movement to the millimeter level, ensuring the ultimate precision for precision machining.
4. Workshop-Friendly, Cost-Saving and Worry-Free
Unlike rail-based flat cars, which require modified flooring and track laying, this trackless flat car utilizes highly wear-resistant rubber wheels or custom industrial wheels, resulting in zero damage to the existing workshop floor, eliminating the time and cost of floor modification. Furthermore, the wheel's vibration-absorbing design reduces driving noise, creating a more user-friendly workshop environment.

 5. "Collaboration" for Efficiency, Connecting the Entire Production Process
It seamlessly collaborates with equipment such as suspended single-girder overhead cranes and gantry cranes: the overhead crane hoists the work-piece from the storage area onto a flat car, which then precisely transports it to the processing station. After processing, the work-piece is then transferred to the next process or inspection area. This creates a highly efficient closed loop of "hoisting + horizontal transfer," improving production flow efficiency by over 40%.
For example, a heavy-duty machine tool manufacturer uses it to transport 18-ton machine tool beds from the welding section to the finishing workshop. The entire process is smooth and the positioning error is less than 5-mm, saving time on leveling during subsequent assembly. A mold manufacturer also uses it to transport large 20-ton stamping molds, nearly doubling mold change efficiency and significantly increasing production line utilization. From being "bulky and difficult to move" to "smooth in the workshop", from "worrying about bumps" to "steady protection", the 25-ton trackless flat car has become the "core aid" for transporting large work-pieces in machining workshops with its advantages of "strong load-bearing capacity, greater flexibility, and ultra-stability", allowing heavy-duty production to also have a "light and smooth experience".
