Supplier's note

  1. Technical Breakthroughs:
    • CE Certification: Meets EU safety standards, enabling global deployment.
    • Dual Max Heights: Accommodates both standard and oversized bridge girder designs.
    • Safety Hook: Reduces operational risks by securing the jack to structures.
  2. Version Selection Guide:
    • Base Model: Optimal for standard bridge projects requiring 50t force and mid-range heights.
    • Advanced Model: Ideal for heavy industrial applications needing 60t capacity and extended stroke lengths.
    • Pro Model: Best for complex projects demanding 70t force, customizable heights, and dual environmental certifications.

With its 50t capacity, you can efficiently stress high-tension cables in bridge construction. The Pro version’s 70t force—40% higher than the base model—enables handling of ultra-heavy loads, while its ISO 14001 certification ensures eco-friendly operation.

⭐ Customer Reviews and Testimonials

Authentic User Feedback

🏗️ Civil Engineering Contractor Reviews

⭐⭐⭐⭐⭐ James Wilkins - Senior Site Engineer
"We’ve used the LEC Hydraulic Ram Jack on three bridge girder projects since purchasing it in February 2025. The 50-ton capacity delivers consistent, precise tensioning, and the CE certification gave us peace of mind during safety audits. The yellow coating stands out on site, improving visibility—critical in busy work zones."

Purchase Date: February 2025 | Usage Period: 5 months

🚧 Infrastructure Project Manager Reviews

⭐⭐⭐⭐⭐ Elena Martinez - Project Manager, Heavy Civil Construction
"After comparing several jacks, we chose the LEC model for its adjustable max height (400mm) and safety hook integration. It’s been rock-solid under repeated high-load cycles. Setup is fast, and the hydraulic response is smooth—no jerking or pressure drops. We’re already ordering a second unit for our next overpass project."

Purchase Date: November 2024 | Usage Period: 8 months

🔧 Field Technician Reviews

⭐⭐⭐⭐☆ David Tran - Field Technician
"Solid build quality. The corrosion-resistant steel body has held up well despite daily exposure to moisture and dust. I appreciate the integrated safety hook—it’s prevented accidental slippage during tension release. Only downside: the hydraulic port could be better protected from debris, but that’s minor. Overall, a reliable tool for demanding jobs."

Purchase Date: April 2024 | Usage Period: 7 months

🏗️ Bridge Fabrication Specialist Reviews

⭐⭐⭐⭐⭐ Olivia Grant - Prefabricated Girder Specialist
"We needed a jack that could handle variable girder profiles without sacrificing precision. The dual height options (315mm/400mm) made this a no-brainer. Switching between configurations took under 15 minutes. The custom stroke length option we requested was delivered on time and performed flawlessly. This isn’t just a jack—it’s a precision engineering tool."

Purchase Date: January 2025 | Usage Period: 6 months

🏗️ Municipal Construction Supervisor Reviews

⭐⭐⭐⭐☆ Marcus Reed - Public Works Supervisor
"Purchased for a city bridge rehabilitation project in August 2024. Now 6 months into use, the jack shows minimal wear despite constant outdoor exposure. The CE-certified hydraulic system operates without leaks, and the protective coating resists chipping even after rough handling. Would rate 5 stars if spare parts were easier to source locally."
