Key Benefits

What This Unit Does Well

Octagonal lifting arm provides higher structural strength and reduces bending under heavy loads
Self-developed load-sensitive hydraulic system ensures smooth operation and energy savings during lifting cycles
Dual-mode engine allows lower fuel consumption during idle or light-duty operation
Digital torque limiter with bus technology reduces false alarms and improves reliability in high-interference environments
Single-cylinder bolt expansion system enhances safety during boom extension by preventing partial collapse
39.5m main boom and 8.3m fly jib extend total reach to 47.8m, suitable for multi-level construction tasks
31750kg curb weight balances stability and road mobility for transport between sites

Application Scenarios

Where It Is Used

Lifting steel beams and precast panels on mid-rise construction sites with narrow access roads
Installing rooftop HVAC units on commercial buildings where crane access is limited to side streets
Supporting bridge deck assembly on rural road projects with uneven ground and no crane pads
Moving heavy machinery between temporary work zones on large infrastructure projects

Fit

Who It Is For

Construction contractors managing multiple site types with tight access and variable load requirements
Machinery dealers stocking mobile cranes for resale in Southeast Asia, Africa and the Middle East
Government infrastructure teams procuring equipment for rural road and bridge projects
Engineering firms needing a crane that can be transported on standard flatbed trailers without oversize permits

Buyer Pain

Problems It Solves

Crane instability or boom deformation when lifting near maximum capacity due to weak arm design
High fuel costs from inefficient engine operation during idle or partial load cycles
Frequent hydraulic system faults caused by poor load sensing and pressure spikes
Delays in site setup due to slow or unreliable boom extension mechanisms
Lack of local spare parts for crane control systems in remote regions

Materials

Materials and Build

High-strength steel for the octagonal lifting arm and boom structure
Cast steel components for the boom pivot and joint housings
Welded steel chassis frame with automatic welding for structural integrity
Rubber bushings and seals in hydraulic cylinders and pivot joints
Steel cab shell with factory paint finish, grey by default

Process

How an Order Is Handled

You provide the site access details, typical load weight, and required reach
We match the QY25K5-I configuration to your lifting needs using available stock or plant build schedules
You confirm the final spec sheet including engine type, cab colour, and tyre choice before deposit
Unit is prepared, tested, and photographed with video of boom operation and engine start
We book RoRo or container shipment and provide export documents including COO, commercial invoice, and packing list

Quality Control

Checks Before Loading

Chassis, engine, and boom serial numbers are photographed and matched to the approved spec sheet
Full boom extension and load-lifting test is recorded on video before loading
Hydraulic system pressure and torque limiter function are verified during test run
Paint, glass, and cab trim are inspected for transport damage at the port

Customisation

What Can Be Changed

Cab colour other than default grey
Tyre brand and spare wheel count
Additional tool box or storage compartment
Engine type selection (SC9DF290Q4, SC8DK280Q4, D10.29A-40) based on fuel availability
Fifth wheel height adjustment for trailer coupling compatibility

Honest Comparison

How It Compares With the Alternatives

Truck crane with standard round boom	The octagonal arm provides better load distribution and less deformation under stress, but is more complex to maintain
Crane with mechanical torque limiter	Digital bus-based limiter has fewer false trips and better durability in dusty or humid environments

Use Guide

Using It Well

Use the dual-mode engine setting for idle or low-load tasks to reduce fuel consumption
Keep the digital torque limiter firmware updated if future software upgrades are released
