Buyer Pain

Problems It Solves

  • High fuel consumption during idle or low-load operations due to non-adaptive engine systems
  • Lifting failures caused by torque limiter interference or outdated mechanical control
  • Delays in setup due to complex or unreliable arm extension mechanisms
  • Lack of spare parts availability for older crane models with no digital control systems
  • Difficulty in transporting cranes over long distances due to excessive weight or non-compliant dimensions
Engineering

Technical Features

  • Octagonal main lifting arm with inserted arm head and embedded sliding block for minimal deformation
  • Self-developed load-sensitive hydraulic system with smooth operation and energy saving
  • Digital torque limiter using bus technology for high anti-interference capability
  • Single cylinder bolt expansion mechanism for improved active safety during extension
  • Dual-mode engine operation to reduce fuel use during low-load or idle phases
  • Automatic welding on main structural parts ensuring zero defects and high reliability
  • 39.5m main boom and 8.3m fly jib for extended reach without additional support
  • Maximum lifting height of 46.6m at full extension with 25-ton capacity at 7.6m radius

Materials

Materials and Build

  • Steel chassis with automatic welding for zero-defect joints
  • Octagonal steel lifting arm with high-strength alloy steel construction
  • Hydraulic cylinders and hoses rated for high-pressure operation
  • Cast steel boom pivot and joint housings for durability under load
  • Rubber-mounted engine and transmission mounts to reduce vibration transmission
Process

How an Order Is Handled

  • You provide the site access conditions, lifting requirements, and transport route
  • We confirm the available QY25K-II units with matching engine, boom, and configuration
  • You approve the final specification sheet, including engine model and optional features
  • The crane is prepared, tested, and photographed before loading
  • We book RoRo or container shipment based on your destination and port access
  • Export documents including commercial invoice, packing list, and certificate of origin are issued
Quality Control

Checks Before Loading

  • All structural welds are inspected using automated systems to confirm zero defects
  • Engine, hydraulic system, and boom extension are tested under load before shipment
  • Torque limiter and control system are verified for digital signal accuracy
  • Final inspection includes full boom extension and retraction cycle with no binding
Customisation

What Can Be Changed

  • Engine model selection from SC9DF290Q4, SC8DK280Q4, or D10.29A-40
  • Optional cab colour or interior finish for operator comfort
  • Additional tool box or storage compartment on the chassis
  • Custom paint scheme or logo application for fleet branding
  • Pre-installation of additional safety lights or warning beacons
Honest Comparison

How It Compares With the Alternatives

Truck crane with mechanical torque limiterDigital bus-based torque limiter reduces false trips and interference, but requires compatible control software
Crane with dual hydraulic cylinders for extensionSingle cylinder bolt expansion is simpler and more reliable, but slower than dual-cylinder systems
Use Guide

Using It Well

  • Use only manufacturer-recommended lubricants for the boom extension mechanism
  • Keep torque limiter calibration records and update if the crane is used in extreme temperature zones

Buyer Questions

Questions About This Unit

Is this crane new or used

All units are new. We confirm the chassis number, engine hours, and build date before shipment.

Can you supply spare parts for this crane later

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

Do you ship by container or RoRo

RoRo is standard. Container shipment is possible but requires lowering the cab and may affect boom clearance. We quote both options for cost comparison.

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.
