Product Overview
The 25 ton hydraulic crane delivers robust lifting performance for medium-scale projects, featuring a hydraulic system that generates 100 kN·m of lifting moment to handle heavy loads with precision. Its compact design (overall length 10.5m × width 2.5m × height 3.2m) makes it ideal for urban lifting tasks where space is limited (e.g., downtown construction sites, residential neighborhoods). Equipped with a 28m 6-section steel boom (Q345B high-strength steel) and 5t removable counterweight, it can lift 25t at 3m radius and 8t at 15m radius—suitable for diverse lifting needs. The crane’s 3.8m wheelbase and 4x2 drive train ensure maneuverability on narrow urban roads (≤8m width).
Product Features
High-Pressure Hydraulic System: 17-21 bar high-pressure hydraulic system with dual hydraulic pumps and pressure relief valves ensures smooth load control, even when lifting 25t loads at 3m radius; prevents load sway via proportional valve adjustment.
Extendable Outriggers: 5.2m-span hydraulic extendable outriggers with rubber pads (300mm diameter) distribute the crane’s 28t operating weight evenly (≤50 kPa ground pressure), maintaining stability on uneven ground like sloped construction sites and gravel lots.
Efficient Winch: 2-speed hydraulic winch with 12mm steel cable (breaking strength 150 kN) lifts loads at 60 m/min (high speed) for light loads (≤5t) and 25 m/min (low speed) for heavy 25t loads; includes a free-fall function for quick cable deployment.
Durable Boom: 28m 6-section steel boom with wear-resistant coating and anti-corrosion treatment handles 25t loads at 3m radius; features a telescoping cylinder with built-in wear sensors to alert operators to maintenance needs.
Applications
Building material hoisting in 5-8 story residential construction: Lifting 1500kg steel beams, 2000kg concrete slabs, and 800kg window frames to heights up to 25m; compatible with beam clamps and concrete slab spreaders.
Heavy equipment installation in factories: Positioning 5t air compressors, 8t milling machines, and 12t generators in industrial facilities; uses lifting slings and shackles for secure load attachment.
Container loading at small ports and warehouses: Lifting 20ft light containers (≤20t) onto trucks or storage platforms; equipped with container spreaders for quick attachment.
Utility pole setting for municipal projects: Erecting 8-12m concrete utility poles (≤5t) for power lines, streetlights, and telecommunications infrastructure; uses pole claws for stable gripping.
FAQ
Q: What’s the minimum turning radius?
A: 8.5 m for maneuvering in urban areas with narrow streets (≤12m width) and tight construction yards, allowing the crane to navigate around existing buildings and obstacles without repositioning.
Q: Does it require special operators?
A: Yes, operators must hold a valid mobile crane operator certification (e.g., CCO certification in the U.S., NPORS certification in the UK, or local equivalent) to ensure safe operation—certification verifies knowledge of load calculations, safety protocols, and crane mechanics.
