Key Benefits

What This Unit Does Well

  • WD615.338 engine is widely used across Chinese truck cranes, so filters, injectors and oil are easy to source locally
  • Double pump confluence system allows simultaneous boom extension and hoisting, reducing cycle time on site
  • 6.9m outrigger span provides stable base for full 50-ton lifting at 3m radius, reducing tipping risk
  • 2000-hour warranty covers major components, reducing long-term maintenance uncertainty
  • Max 85km/h travel speed allows fast relocation between job sites on paved roads
  • Air-assisted gear shift improves driver comfort during frequent repositioning and travel
Application Scenarios

Where It Is Used

  • Heavy lifting at oil and gas construction sites where 50-ton capacity and 57.7m height are required
  • Bridge and power plant construction with tight access roads and need for rapid crane setup
  • Infrastructure projects in Southeast Asia and Africa where crane parts must be available within 30 days
  • Mining site operations requiring frequent crane repositioning and reliable lifting under high load
Fit

Who It Is For

  • Contractors managing large-scale infrastructure or industrial projects needing 50-ton lifting capacity
  • Machinery dealers stocking truck cranes for resale in markets with limited access to OEM parts
  • Fleet managers replacing older cranes with units that share engine and hydraulic components
  • Government procurement teams sourcing equipment with documented warranty and local service support
Buyer Pain

Problems It Solves

  • Lifting operations delayed by crane breakdowns due to rare or unavailable spare parts
  • Inconsistent performance on site due to outdated hydraulic systems or single pump designs
  • Lack of warranty coverage for critical components, leaving buyers exposed to repair costs
Engineering

Technical Features

  • We coordinate shipping to your designated port and provide export documentation
Quality Control

Checks Before Loading

  • Engine, hydraulic system and boom operation are tested under load before shipment
  • All welds and structural joints are inspected for integrity and fatigue signs
  • Outrigger extension and retraction cycles are timed and recorded for consistency
  • Loading and lashing photos are sent before vessel departure
Customisation

What Can Be Changed

  • Outrigger extension length or jib configuration for site-specific lifting needs
  • Cab colour or interior finish to match fleet branding
  • Additional lighting or warning systems for night or high-visibility operations
  • Custom mounting brackets for auxiliary tools or winch attachments
  • Pre-installation of service access panels for easier maintenance
Honest Comparison

How It Compares With the Alternatives

40-ton truck craneThe 50-ton unit handles heavier loads at full radius but has higher fuel consumption and requires more space for outrigger setup
Crawler crane with fixed baseThe truck crane offers faster relocation between sites but has lower stability at maximum lift compared to a fixed crawler
Crane with single pump systemDouble pump confluence allows faster boom and hoist cycles, reducing cycle time on high-frequency jobs
Use Guide

Using It Well

  • Run the first 100 hours at reduced load to allow hydraulic and mechanical systems to settle
  • Inspect outrigger pads and ground contact points before each setup to prevent sinking
  • Use the recommended oil grade for WD615.338 engine to avoid injector clogging
  • Keep spare hydraulic hoses and seals on site to avoid delays during breakdowns
