Precision Lifting Tools for Industrial Warehouses & Heavy Platforms
🛠️ Precision Lifting Tools – Technical Operation & Operator Assistance
The Precision Lifting Tool, featuring a step wedge design, is engineered to safely and progressively elevate heavy platforms or equipment in areas where clearance is too limited for forklift tines. Its low‑profile geometry allows insertion into tight gaps, enabling controlled lift without the need for conventional lifting machinery.
🔧 How It Works
- Progressive Lift Control: The stepped wedge profile provides incremental lifting, giving operators precise control over elevation without sudden shifts or instability.
- Low‑Profile Insertion: The tapered leading edge enables easy placement between objects or under components with minimal clearance.
- Load Distribution: The wide base and stepped geometry distribute force evenly, reducing the risk of flange damage or misalignment.
- Safety Features: Anti‑slip surfaces and mechanical stops prevent over‑extension or slippage under load.
👷 Operator Benefits
- Hands‑Free Elevation: Minimizes the need for crowbars, prying, or manual lifting—reducing pinch‑point hazards and ergonomic strain.
- Compact & Portable: Lightweight design allows easy transport and use in confined or elevated workspaces.
- Compatible with Fit‑Up Tools: Often used in conjunction with forklifts for added versatility.
Variants: Precision Lifting Tools
- Dual-Wedge Action: The tool features two interlocking forged steel wedges—one fixed and one mobile. When pressurized hydraulic fluid is applied, the mobile wedge slides over the base wedge, converting horizontal force into vertical lift.
- Step Engagement: The stepped wedge profile allows incremental lifting with secure mechanical engagement at each stage, preventing slippage and enabling precise elevation control.
- External Hydraulic Interface: The WJ19K, a variant of the precision lifting tools, connects to standard 700 bar (10,000 psi) hydraulic systems, delivering up to 183 kN (18.3 metric tons) of lifting force.
🔧 Operating Principle
🧰 WJ19K Hydraulic Lifting Wedge Jack – Technical Description
The WJ19K is a high-force hydraulic lifting wedge engineered for precision lifting, pushing, and spreading in flange alignment, gasket replacement, and confined-access maintenance tasks. Unlike the WJ19P, the WJ19K operates with an external hydraulic pump, making it ideal for teams already equipped with 10,000 psi power packs and seeking compact, modular lifting solutions.

The WJ19P, is a compact, high-force variant of the precision lifting tools designed for precision lifting, pushing, and spreading in tight-access industrial environments. Engineered with an integrated hydraulic cylinder and pump unit, the WJ19P eliminates the need for external power sources, making it ideal for remote or confined field operations.
🔧 Operating Principle
- Step Engagement: The stepped profile allows incremental lifting with secure mechanical engagement at each stage, preventing slippage and ensuring controlled elevation.
- Self-Contained Hydraulic System: The integrated 10,000 psi pump delivers up to 183 kN (18.3 metric tons) of lifting force without external hoses or power packs.
- Dual-Wedge Action: The tool features two interlocking steel wedges—one fixed and one mobile. As the operator actuates the built-in hydraulic pump, the mobile wedge slides forward over the base wedge, converting horizontal motion into vertical lift.
