Key Benefits

What This Unit Does Well

  • Octagonal main boom provides higher structural rigidity and lifting capacity compared to round booms
  • Self-developed load-sensitive hydraulic system reduces fuel consumption during partial load cycles
  • Single-cylinder bolt expansion mechanism improves stability and reduces risk of boom collapse during extension
  • Digital bus torque limiter resists electrical interference and maintains consistent protection in dusty or humid environments
  • Dual-mode engine operation allows lower RPM for idle or light work, reducing fuel use on site
  • Automatic welding on main structural parts ensures consistent joint quality and long-term reliability
  • 39.5m main boom with 8.3m fly jib gives a total reach of 47.8m, suitable for multi-story building and bridge work
  • 31750kg curb weight allows transport on standard highway trailers without special permits
Application Scenarios

Where It Is Used

  • Urban construction site with narrow access roads and limited space for crane setup
  • Power line tower assembly in remote areas where crane must be transported over unpaved roads
  • Industrial plant maintenance where the crane must be moved between multiple work zones daily
Fit

Who It Is For

  • Construction contractors managing multiple site types with limited crane storage space
  • Engineering teams requiring a crane that can be driven directly to the work zone without disassembly
  • Machinery dealers stocking mobile cranes for resale in Southeast Asia and Africa
  • Government infrastructure projects needing a crane with documented ISO9001:2008 compliance for procurement
Buyer Pain

Problems It Solves

  • Crane downtime caused by long lead times for parts when using imported brands with fragmented supply chains
  • Inconsistent boom performance due to poor weld quality or non-standard materials in low-cost cranes
  • Fuel inefficiency on light lifts caused by fixed-rate hydraulic systems that cannot adapt to load
  • Lack of local support for digital torque limiters that fail under high vibration or moisture
  • Overweight cranes that require special transport permits and additional logistics costs
Engineering

Technical Features

  • Octagonal main boom with inserted arm head and extended embedded sliding block for minimal deformation
  • Self-developed load-sensitive hydraulic system with smooth operation and energy recovery
  • Single-cylinder bolt expansion technology for controlled and safe boom extension
  • Digital bus torque limiter with low failure rate and high resistance to electrical noise
  • Automatic welding on main structural components ensuring zero defect joints
  • Dual-mode engine operation for fuel savings during idle or partial load
  • SC9DF290Q4 or D10.29A-40 diesel engine with 213kW output at 2200rpm
  • Main boom length: 39.5m, Fly jib: 8.3m, Total extended reach: 47.8m
  • Maximum lifting height: 46.6m at 7.6m radius
  • Rated lifting capacity: 25 tons at 7.6m radius
  • Rated lifting moment: 961kN.m
  • Chassis length: 12300mm, Width: 2500mm, Height: 3350mm
  • Curb weight: 31750kg

Materials

Materials and Build

  • Steel chassis with automatic welding on main load-bearing sections
  • Octagonal steel boom with high-strength alloy steel for the arm head and sliding block
  • Cast steel boom pivot and cylinder mounting brackets
  • Rubber vibration dampers on engine and transmission mounts
  • Galvanised steel frame for the cab and operator platform
Process

How an Order Is Handled

  • You provide the site access dimensions, maximum lift height, and typical load weight
  • We confirm the QY25K-II configuration matches your lifting and transport needs
  • You approve the final specification sheet, including engine model, boom length, and cab layout
  • Unit is prepared, tested, and photographed with engine start and boom extension recorded on video
  • We book RoRo or container shipment based on your port and customs requirements
  • Export documents including commercial invoice, packing list, bill of lading, and certificate of origin are issued
Quality Control

Checks Before Loading

  • Engine, transmission, and boom serial numbers are photographed and matched to the approved spec sheet
  • Full boom extension and retraction cycle is recorded on video to verify smooth operation
  • All weld joints are inspected visually and by non-destructive testing at the factory
  • Torque limiter and hydraulic system are tested under simulated load conditions
Customisation

What Can Be Changed

  • Cab colour other than standard grey
  • Optional additional tool box or storage rack on the chassis
  • Engine model selection between SC9DF290Q4 and D10.29A-40
  • Fly jib length adjustment within the 8.3m standard range
  • Mounting for additional lights or warning beacons on the boom
Honest Comparison

How It Compares With the Alternatives

Crane with multi-cylinder boom extensionSingle-cylinder bolt expansion is simpler to maintain but slower to extend than multi-cylinder systems
Use Guide

Using It Well

  • Keep the digital torque limiter firmware updated if future upgrades are available
  • Use the dual-mode engine in low-RPM mode during idle or light lifting to save fuel

Buyer Questions

Questions About This Unit

Is this crane new or used

All units are new. We supply directly from the factory with full documentation and a 12-month warranty.

Can you supply spare parts for this crane later

Yes. We supply standard parts like hydraulic hoses, filters, boom pins, and torque limiter modules. They can be shipped separately or consolidated with the crane.

Do you ship by container or RoRo

RoRo is standard for truck cranes. Container shipment is possible but requires lowering the cab and may affect boom clearance.

What documents do I get for customs

Commercial invoice, packing list, bill of lading, certificate of origin, and ISO9001:2008 certificate are included. Pre-shipment inspection certificates are available upon request.
