Key Benefits

What This Unit Does Well

Octagonal lifting arm provides higher structural strength and reduced deformation under heavy load
Self-developed load-sensitive hydraulic system ensures smooth operation and energy savings
Digital torque limiter with bus technology reduces interference and improves reliability
Dual-mode engine allows lower fuel consumption during idle or light-duty work
Single-cylinder bolt expansion technology enhances stability and safety during boom extension
39.5m main boom and 8.3m fly jib extend reach to 47.8m for high-level lifting tasks
31750kg curb weight balances mobility and stability on uneven terrain
ISO9001:2008 certification confirms documented quality control in manufacturing

Application Scenarios

Where It Is Used

Lifting steel beams and precast panels at mid-rise construction sites with narrow access roads
Installing rooftop HVAC units on commercial buildings where crane access is restricted
Supporting bridge component assembly in remote areas without dedicated crane transport
Moving heavy machinery between temporary work zones on large infrastructure projects

Fit

Who It Is For

Construction contractors managing multiple site locations with tight access
Engineering teams requiring a crane that can operate on unpaved or soft ground
Machinery dealers stocking mobile cranes for resale in Southeast Asia and Africa
Government procurement teams sourcing equipment for road and bridge projects

Buyer Pain

Problems It Solves

High fuel costs from inefficient engines during idle or partial-load operations
Boom collapse or instability during extension due to weak expansion mechanisms
Lack of spare parts or technical support for foreign-made cranes in remote markets
Inconsistent performance from cranes with analog torque limiters prone to failure

Engineering

Technical Features

Octagonal lifting arm with inserted arm head and embedded sliding block for smooth extension
Self-developed load-sensitive hydraulic system with digital control and energy-saving function
Single-cylinder bolt expansion technology for improved active safety during extension
Digital torque limiter using bus technology with low failure rate and strong interference resistance
Main structural parts manufactured with automatic welding for zero-defect welds
Dual-mode engine operation to reduce fuel use during low-load phases
39.5m main boom and 8.3m fly jib extend total reach to 47.8m
Maximum lifting height of 46.6m at full extension with 25-ton capacity at 7.6m radius
Chassis based on Dongfeng platform with 31750kg curb weight and 12300mm overall length

Materials

Materials and Build

Steel frame and lifting arm with high-strength alloy steel construction
Automatic welded joints on main structural components with zero defect verification
Hydraulic cylinders and hoses rated for high-pressure operation in continuous lifting
Rubber bushings and seals in boom joints for vibration damping and wear resistance
Dongfeng chassis with steel ladder frame and load-bearing suspension system

Process

How an Order Is Handled

You send the site access details, lifting height requirement, and typical load weight
We match the QY25K-II configuration to your site constraints and confirm availability
You review the final spec sheet, including engine model, boom length, and warranty terms
Unit is prepared, tested, and photographed with video of boom extension and engine start
We book RoRo or container shipment based on your port and delivery timeline

Quality Control

Checks Before Loading

Chassis, engine, and boom serial numbers are cross-checked against the specification sheet
Full boom extension and retraction cycle is recorded on video with load test data
Hydraulic system pressure and torque limiter function are verified before loading
Paint, glass, and cab integrity are inspected at the loading yard for transport damage

Customisation

What Can Be Changed

Engine model selection from SC9DF290Q4, SC8DK280Q4, or D10.29A-40
Boom length adjustment within standard QY25K-II range (39.5m main arm, 8.3m fly jib)
Cab colour or interior trim change from standard configuration
Additional tool box or storage compartment on the chassis side
Mounting brackets for site-specific accessories like lights or cameras

Honest Comparison

How It Compares With the Alternatives

Fixed crane on a trailer	The truck crane moves between sites without disassembly but has lower maximum height and reach
Crane with analog torque limiter	Digital bus-based limiter reduces false alarms and improves safety during high-load lifts

Use Guide

Using It Well

Inspect boom joints and pin connections monthly for wear or misalignment
Use only the recommended engine oil and hydraulic fluid grades to avoid system damage
Store the crane with boom fully retracted and secured to prevent wind load damage
