Product Details

① Product Overview

This 12-ton truck crane is a heavy-duty lifting machine designed for construction, mining, infrastructure and small-scale urban engineering projects.

It is widely used in urban construction sites, small engineering operations and mining sites, with excellent flexibility and site transfer efficiency.

It is especially suitable for contractors, fleet operators and mining companies who require compact design, precise lifting and reliable performance in limited working spaces.

② Key Features

Compact Design for Urban & Small Site Access

The 3-axle structure ensures a compact body size, allowing the crane to enter narrow urban areas and small construction sites.

It solves the problem of limited working space in urban projects and small-scale engineering, avoiding the inconvenience of large cranes being unable to access.

It brings higher operational flexibility and faster site transfer efficiency, helping customers complete lifting tasks in complex environments quickly.

12 Ton Truck Crane

Dual-Pump Intelligent Flow Distribution for Precise & Efficient Lifting

The electro-hydraulic control system adopts dual-pump intelligent flow distribution, with pressure-boosted buffering and sequential braking technology.

It addresses the issues of slow combined-motion response, large impact and poor control precision in traditional hydraulic systems.

It delivers fast response, minimal impact and millimeter-level precise lifting (single-rope speed 1.2m/min, slewing speed 0.1°/s), improving operational safety and fuel efficiency while reducing equipment wear.

High-Performance Chassis for Long-Term Reliability

The chassis uses a new structural frame that has passed 200,000 cycles of fatigue testing.

It solves the problem of structural fatigue and low reliability under long-term heavy-duty operations, especially in harsh mining and construction conditions.

It ensures stable load-bearing capacity and extended service life, reducing maintenance costs and downtime for customers.

12 Ton Truck Crane

Intelligent Control System for Efficient Operation & Maintenance

The CAN bus system integrates controllers, displays, instruments, I/O modules and sensors, with a fault diagnosis system (BCM module) and Sany load limiter.

It addresses the issues of slow response, difficult fault location and potential safety risks from overload in traditional control systems.

It provides rapid system response, accurate fault positioning and overload/over-lowering/over-winding protection, improving operational efficiency and safety while simplifying maintenance.

Precise & Economical Control for Cost Optimization

Hydraulic valves and components achieve superior micro-movement performance, combined with load sensing and constant power technology.

It solves the problems of poor control accuracy and high fuel consumption in heavy-duty lifting operations.

It enhances lifting precision while optimizing fuel efficiency, reducing operating costs and improving economic benefits for customers.

Mining & Heavy-Duty Earthmoving Projects

The reinforced chassis and high load capacity adapt to harsh mining conditions, providing reliable lifting support for ore handling, equipment maintenance and large-scale earthmoving operations, with excellent fatigue resistance and stability.

Infrastructure & Road Construction

The long boom length and precise control system meet the lifting needs of bridge construction, road maintenance and power facility installation, ensuring efficient and safe operation in large-scale infrastructure projects.

⑤ Model Comparison

Model	Lifting Capacity	Boom Length (Full Extension)	Application Scenario
12t Truck Crane	12t	28.1m	Urban construction, small engineering, mining
16t Truck Crane	16t	30.5m	Large-scale construction, heavy-duty mining
20t Truck Crane	20t	34.2m	Super-large infrastructure, industrial installation

The 12-ton model is suitable for customers who focus on compactness and flexibility in urban and small-scale projects.

The 16-ton model is recommended for those who require higher load capacity in medium-to-large mining and construction projects.

If your project needs ultra-long boom and heavy-load lifting, the 20-ton model is a better choice.

⑥ Buying Guide: How to Choose the Right Model

Define Your Working Conditions

Road condition: For narrow urban roads, choose the 12-ton compact model; for rough mining sites, prioritize models with reinforced chassis and high ground clearance.
Payload & lifting height: Match the lifting capacity and boom length to your maximum load and operating height requirements.
Daily working hours: For long-term continuous operation, select models with high fatigue resistance and reliable cooling systems.

Select the Proper Configuration

Engine & transmission: Choose engines with sufficient power and fuel-efficient transmission systems to ensure stable output under heavy load.
Axle & suspension: 3-axle configuration offers a balance of load capacity and flexibility; reinforced suspension improves stability in harsh conditions.
Hydraulic & control system: Prioritize intelligent flow distribution and CAN bus control systems for precise lifting and easy maintenance.
