HYDRAULIC JACKS

Hydraulic Jacks with Manual Pumping Units

Product Code: MSI 2062 (Series MSI 2062A to MSI 2062G)

The Hydraulic Jacks series offers multipurpose utility across a broad spectrum of structural and geotechnical testing applications. Engineered for maximum reliability under extreme force, these systems are used for real-time field load investigations, determination of the load-carrying capacity of piles, tensioning wires in pre-stressed concrete members, and analyzing structural deformation characteristics.

Every hydraulic jack system comes fully integrated with a hand-operated hydraulic pumping unit, a high-precision Bourdon tube type load gauge, and a heavy-gauge high-pressure flexible hose pipe. The standard configuration models feature a uniform piston stroke travel of 50 mm. For added operator convenience, all jack models scaling up to a 1000 kN capacity are equipped with built-in internal retraction springs for automatic piston resetting.

🎯 Applications

• Field Pile Load Capacity Determination & Foundation Testing

• Tensioning of Structural Wires in Pre-Stressed Concrete Structures

• Deformation & Displacement Testing of Structural Members

• On-Site Geotechnical & Geological Field Investigations

• Civil Engineering & Specialized Structural Testing Laboratories

• Bridge Construction, Dam Site Audits, & Infrastructure Projects

⭐ Features

• Multipurpose Utility Scope: Easily adapts to field foundation testing, laboratory structure loading frames, and prestressing wires.

• Automatic Piston Return: Systems up to 1000 kN capacity feature robust retraction springs that automatically pull the ram back post-test.

• Precision Load Tracking: Outfitted with an expertly calibrated Bourdon tube analogue dial indicator tailored to each model's maximum capacity.

• Rugged Fluid Transmission: Supplied complete with a flexible high-pressure hydraulic hose pipe to maintain system pressure safely at a distance.

• Independent Powering: Hand-operated double-acting manual pump provides excellent, gradual force control without needing electrical grid power.

• Customisable Travel Stroke: While the standard piston stroke is 50 mm, customized travel ranges up to 150 mm can be fabricated upon request.

🔬 Working Principle

The hydraulic jack cylinder is structurally positioned against the pile or structural beam member under test. The manual pumping unit is connected via the high-pressure flexible hose pipe, and the bleed valve is closed. By operating the manual pump lever, hydraulic fluid is driven into the cylinder chamber, acting on the precision-machined piston area (ranging from 50 mm up to 272.2 mm depending on the model chosen).

This fluid pressure forces the piston outward through its 50 mm travel stroke, applying a direct, linear load onto the structural component. The pressure is cross-referenced live on the integrated Bourdon dial indicator. Once testing thresholds are met, releasing the pressure valve triggers the internal springs (on models up to 1000kN) to cleanly pull the piston back to its starting base line.

💡 Advantages

• Covers all structural fields with an expansive capacity envelope starting from a nimble 50 kN scaling up to a massive 3000 kN.

• Simplifies multi-stage field loading cycles through fine analogue gauge increments (least count down to 0.2 kN).

• Guarantees testing independence on deep remote pipeline or piling foundations without requiring electrical generators.

• Built-in safety margins in the high-pressure hose and steel housings prevent catastrophic bursting during peak operations.
