STMA 16Ton Forklift with Triplex Full Free Lift Mast
Redefining Heavy-Duty Logistics in Height-Restricted Environments
STMA FORKLIFT has announced a significant configuration upgrade to its 16-ton heavy-duty diesel forklift, now offering an optional triplex full free lift mast system with a maximum lift height of 6 meters. Engineered with industry-leading collapsed height and superior lifting performance, this upgrade effectively resolves critical industry pain points, including restricted overhead clearance, limited indoor warehouse operability, and low efficiency in high-level stacking. Compared to traditional duplex masts of equivalent lift heights, this triplex mast delivers a structural performance revolution, significantly enhancing scenario adaptability and operational flexibility for heavy material handling. It provides a high-performance solution for diverse applications, including industrial and mining enterprises, warehousing and logistics, port yards, and container handling.
Conventional duplex masts with a 6-meter maximum lift height typically result in a collapsed (lowered) height of approximately 5 meters. This excessive collapsed height severely restricts heavy-duty forklifts from operating in standard factories, indoor warehouses, and height-limited aisles. In contrast, the STMA triplex full free lift 6-meter mast utilizes a three-stage telescopic structure and an optimized lightweight, high-strength I-beam (channel) architecture to precisely control the collapsed height to 3.7 meters. This creates an extreme height differential of 1.3 meters, fundamentally breaking the spatial operational barriers of heavy-duty forklifts in its class. This dimensional advantage ensures seamless compatibility with standard warehouse entrances, height-restricted facility aisles, and municipal bridges, liberating high-capacity forklifts from outdoor-only limitations and enabling true indoor-outdoor universal operation.
In terms of core operational performance, this triplex full free lift mast achieves a maximum lift height of 6 meters, with a maximum overhead guard height of 7.2 meters. It fully satisfies the rigorous demands of high-rack storage, top-tier heavy cargo loading/unloading, and large equipment stacking, effectively unlocking vertical storage potential to increase warehouse storage density and reduce facility leasing and operational costs. Leveraging mature full free lift hydraulic technology, the equipment offers substantial free lift capacity. This allows the forks to elevate loads without extending the upper sections of the mast, making it perfectly suited for low-clearance, enclosed environments such as shipping containers and confined warehouses. This capability effectively prevents mast-to-ceiling collisions, cargo scraping, and equipment jamming, delivering significantly enhanced operational safety and precision compared to traditional duplex mast systems.
Regarding structural stability and durability, the mast incorporates a precision roller guide system and a synchronized hydraulic control system, complemented by a multi-cylinder synergistic drive design. This ensures smooth operation, high positioning accuracy, and stable performance throughout the telescoping, lifting, and tilting processes. The three-stage segmented telescopic structure effectively distributes operational stress, minimizing mast deformation and wear, thereby extending equipment lifespan and reducing long-term maintenance costs.
Under full-load and heavy-duty conditions, the equipment maintains exceptional center-of-gravity stability and anti-drift capabilities, making it ideal for high-frequency transfer and stacking of heavy materials such as steel, stone, large palletized goods, and container components. Furthermore, STMA offers a comprehensive range of specialized attachments to accommodate various heavy-duty cargo handling requirements.
The introduction of this triplex full free lift mast underscores STMA’s profound technical accumulation in the heavy-duty logistics equipment sector. By replacing traditional duplex masts with triplex full free lift masts, STMA achieves multidimensional performance breakthroughs for its 16-ton heavy-capacity forklifts: a 3.7-meter collapsed height, a 6-meter maximum lift height, and universal spatial adaptability. Moving forward, STMA will continue to focus on scenario-driven technological innovation, consistently optimizing the core configurations of heavy-duty forklifts to empower the industrial logistics industry with cost reduction, efficiency enhancement, and safe, high-performance operations.
