Heavy-Lift, Threaded Ram with Safety Lock Nut Cylinders
Heavy-Lift High-Tonnage Threaded Nut Cylinders are engineered for industrial applications requiring maximum lifting capacity and reliable load holding. Featuring a robust threaded-nut mechanism, these cylinders provide mechanical load retention, ensuring the lifted load remains secure even after hydraulic pressure is released. Designed for heavy-duty lifting, jacking, and structural support, they are ideal for foundations, bridge supports, machinery positioning, and industrial maintenance tasks.
Built from high-strength alloy steel with precision machining, these cylinders deliver consistent performance under demanding conditions.
Technical Specifications:
Cylinder Capacity : 10-100 ton.
Stroke : 50-150 mm.
Closed Height : 150-475 mm.
Material : Steel.
Applications:
- Lifting and jacking heavy equipment in industrial plants and factories.
- Foundation levelling and adjustment during construction projects.
- Bridge support and structural alignment in civil engineering applications.
- Maintenance and overhaul of heavy machinery and large mechanical assemblies.
- Precise positioning of large components in fabrication workshops .
- Load support during shutdowns, retrofitting, or equipment replacement.
- Controlled lifting and holding in mining, power, and infrastructure projects.
- High-load tasks requiring sustained mechanical load holding over time.
- Heavy-duty lifting in confined spaces where standard jacks are insufficient.
- Multi-point lifting and alignment for structural or industrial installations.
Key Features:
Designed with strong materials and robust manufacturing to withstand harsh environments, heavy loads, and repeated use under demanding conditions.
Available in capacities ranging from 10 ton up to 1000 ton — suitable for heavy lifting, jacking, and load-bearing applications in industrial, construction, and infrastructure settings.
Multiple models offer different stroke lengths and closed heights — giving flexibility to choose the cylinder that best fits the job’s lifting height and clearance requirements.
Because of the mechanical lock-nut design, the cylinder ensures secure load retention — suitable for foundation work, structural support, bridge jacking, and similar critical lifting tasks.
Equipped with a heavy-duty threaded nut that mechanically locks the load after lifting, enabling sustained support even when hydraulic pressure is released — ideal for jobs requiring long periods of load holding or waiting.
Mechanical locking reduces dependence on hydraulic pressure alone, lowering risk of unintended load drop — critical for safety in structural, construction, and maintenance work.
Suitable for tasks such as foundation levelling, bridge support, heavy equipment jacking, structural alignment, maintenance, and other high-load lifting/support operations.
