In the dynamic worlds of construction, road rescue, and industrial maintenance, equipment that balances mobility with performance is a game-changer. Teams need cranes that can move quickly between job sites, fit into tight spaces, and deliver reliable lifting power—all while keeping operations efficient. The SUNHUNK K108 Knuckle Boom Crane checks every box, embodying the core advantages of “Lightweight and Portable, Efficient Operation” with nine standout features. Let’s dive into why this crane is becoming the go-to choice for businesses worldwide.

1. Two Extendable Boom Sections: 8.15m Working Range for Versatility

Portability doesn’t limit reach with the SUNHUNK K108. Its two extendable boom sections deliver a maximum working range of 8.15 meters—perfect for tasks like loading/unloading trucks, installing streetlights, or supporting road rescue operations. This range lets operators tackle jobs that would otherwise require bulkier equipment, all while keeping the crane nimble. As a top-tier 8.15m working range extendable boom crane, it balances flexibility and stability, making it ideal for diverse on-site needs.

2. High-Strength Steel Body: 1600kg Lightweight Design for Easy Mobility

The K108’s portability starts with its smart construction: the main body plate uses high-strength steel, ensuring structural durability while keeping the crane’s weight at just 1600kg. This means it can be transported via standard trucks (no heavy-duty haulers needed) and positioned quickly—even in narrow urban areas or small factory yards. Despite its light weight, it handles a rated load of 5000kg, proving “lightweight” doesn’t mean “low performance.” For teams prioritizing mobility without sacrificing strength, the K108 is the ultimate high-strength steel 1600kg crane.

3. Customized Hydraulic Key Components: Boost Efficiency & Competitiveness

Efficiency relies on tailored performance, and the SUNHUNK K108 delivers with customized hydraulic key components. These parts are engineered specifically for the crane’s needs, optimizing boom speed, reducing energy waste, and minimizing wear. Unlike generic hydraulics, this customized system ensures smoother movement and faster response times—critical for meeting tight project deadlines. As a leading customized hydraulic component crane, it outperforms off-the-shelf models, helping businesses stay competitive.

4. Optional Four-Section Extendable Boom: Personalize for Unique Needs

Every job is different, and the K108 adapts with an optional four-section extendable boom. For tasks requiring extra reach—like high-rise maintenance or large factory equipment installation—this upgrade extends the crane’s capabilities without needing a separate specialized machine. Whether you choose two or four sections, the K108 maintains stable operation, making customization practical and cost-effective.

5. Compliance with Domestic & International Standards: Global Reliability

Safety and regulatory adherence are non-negotiable, and the SUNHUNK K108 meets both domestic and international standards. This means it can be used in global markets—from local construction to international road rescue—without costly modifications. Compliance ensures it follows strict safety guidelines, protecting operators and loads, no matter where you work.

6. High-Quality Hydraulic Valve Lock: Maximize Reliability

The K108 uses a high-quality brand hydraulic valve lock to prevent leaks, maintain pressure stability, and avoid unexpected downtime. This critical safety feature holds the boom securely during lifts, reducing accident risks. By choosing trusted components, the crane ensures long-term reliability, lowering maintenance costs and keeping operations on track.

7. Manual Flip Vertical Cylinder: Simple, Flexible Operation

Ease of use drives efficiency, and the K108’s manual flip vertical cylinder delivers just that. It lets operators adjust the cylinder quickly—no complex electrical systems that fail in harsh conditions (like dust or rain). This design ensures stability for tasks like brick lifting or equipment relocation, simplifying operation and reducing training time.

8. High-Pressure Filter: Extend Continuous Operation

A standard high-pressure filter keeps the K108’s hydraulic oil clean, removing contaminants that damage valves and pumps. This extends the crane’s continuous operating ability, cutting interruptions for maintenance and keeping productivity high.

9. Rack & Pinion Swivel Structure: Smooth, Powerful Positioning

Precise load placement matters, and the K108’s rack and pinion swivel structure delivers 360° smooth, powerful swiveling. Unlike jerky chain-driven systems, it ensures consistent movement even under heavy loads—perfect for tight spaces like factory interiors. As a top rack and pinion swivel crane, it reduces operator fatigue and improves accuracy.

Why the SUNHUNK K108 Is Your Best Choice

The SUNHUNK K108 isn’t just a crane—it’s a solution that embodies lightweight portable crane advantages. It combines high-strength steel mobility, customized hydraulics, flexible booms, and smooth swiveling to solve real-world challenges. Whether you’re in construction, rescue, or maintenance, it saves time, cuts costs, and boosts productivity.
