Weighing & Specification Parameters for Aircraft Maintenance Hydraulic Jacks

Aircraft maintenance hydraulic jacks are critical ground support equipment (GSE). The complete system consists of custom hydraulic cylinders and hydraulic power units, widely used for landing gear replacement, tire service, aircraft weighing and full-aircraft jacking for commercial jets, business jets and helicopters. Load and weighing specifications are the top priority during procurement, which directly affects aircraft structural safety and aviation compliance.

Our heavy-duty hydraulic cylinders are not limited to aerospace maintenance. They also serve oil tank synchronous jacking, bridge lifting, building relocation, mining heavy support and marine lifting applications. We offer single-acting / double-acting cylinders and custom synchronous hydraulic power units, supporting OEM & ODM for global equipment manufacturers and GSE suppliers.

Core Weighing & Specification Parameters

1. Rated Load and Safety Margin Aircraft jack load capacity includes rated working load, proof load and burst load. A high safety factor is built into the design. The proof load is at least 1.5 times rated capacity to resist eccentric load and impact. Available tonnage covers 3 ton, 12 ton, 25 ton, 65 ton, 100 ton and custom sizes.

2. Stroke & Min / Max Lifting Height Cylinder stroke is customized for aircraft jack point clearance, including hydraulic travel plus mechanical extension sleeves. Collapsed height and fully extended height are engineered to fit tight hangar space, easy storage and long lifting travel.

3. System Operating Pressure Hydraulic cylinders match perfectly with hydraulic power units. Rated pressure and overflow protection pressure are preset. Built-in hydraulic lock keeps load locked if pressure loss or hose rupture occurs, preventing aircraft drop and meeting GSE safety standards.

4. Synchronous Control for Aircraft Weighing For full aircraft weighing and multi-point jacking, PLC synchronous hydraulic systems are optional. Real-time pressure and displacement monitoring across multiple cylinders ensures even load distribution to avoid fuselage stress deformation and maintain weighing precision.

Procurement Guidance

Aircraft maintenance hydraulic jacks are highly custom products. Aircraft model, jack point layout, gross aircraft weight and hangar conditions determine cylinder tonnage, stroke and power unit setup. Off-the-shelf cylinders rarely meet aviation weighing and safety requirements.

UNL Hydraulic delivers complete hydraulic solutions for aircraft maintenance jacks, including custom hydraulic cylinders, hydraulic power units and synchronous control systems. Factory load test reports and pressure certificates are available for global project support. Equipment manufacturers and GSE suppliers are welcome to request technical proposals and quotations.
