  • Cast steel components for boom pivot and extension joints
  • Automatic welded joints on main load-bearing structures with zero defect verification
  • Steel chassis with factory paint finish, grey by default
  • Hydraulic hoses and seals rated for high-pressure operation in construction environments
Process

How an Order Is Handled

  • You provide the site access conditions, typical lift weight, and required reach
  • We confirm the available stock or production schedule for QY25K-II with your preferred engine option
  • You review the final specification sheet, including boom length, engine model, and cab configuration
  • We prepare the unit, photograph and video record the engine, chassis, and boom systems before loading
  • We book RoRo or container shipment and issue the export documents required for customs clearance
Quality Control

Checks Before Loading

  • Chassis, engine, and boom serial numbers are photographed and matched to the approved specification sheet
  • Hydraulic system pressure test and boom extension/retraction are recorded on video before loading
  • Paint, glass, and cab trim are inspected for damage during transport preparation
  • Loading and lashing photos are sent before the vessel departs
Customisation

What Can Be Changed

  • Cab colour other than the default grey
  • Engine model selection between SC9DF290Q4, SC8DK280Q4, or D10.29A-40
  • Additional tool box or storage compartment on the chassis

Honest Comparison

How It Compares With the Alternatives

Hydraulic crane with manual controlThe digital torque limiter and load-sensitive system reduce operator error and improve safety, but require trained personnel for full use
Used crane from EuropeNew QY25K-II has a 12-month warranty and full spare parts availability, while used units may lack documentation and have unknown maintenance history
Use Guide

Using It Well

  • Inspect boom extension joints and bolts weekly for wear or loosening
  • Use only manufacturer-recommended hydraulic oil and filters to avoid system damage
  • Store the crane with boom fully retracted and secured when not in use to prevent wind damage
