HIGH-EFFICIENCY TIMBER & LOG LOADING SOLUTION

The Terra Knuckle Boom Crane with Wood Grappler (also known as a Log Loader or KMU with Grapple) is the professional choice for the forestry, recycling, and municipal industries. Unlike stiff boom cranes, its folding articulated design allows for maximum flexibility in loading and unloading logs, waste, and scrap. Whether you are in the Amazon, Southeast Asian forests, or Northern Europe, this crane is built for heavy-duty operational efficiency.

WHY CHOOSE OUR LOG LOADER CRANE?

SUPERIOR FOLDABLE DESIGN

The knuckle boom (articulated) design allows the crane to fold compactly behind the cab, saving valuable truck bed space for maximum timber payload.

HIGH-STRENGTH HYDRAULIC GRAPPLER

Equipped with a 360-degree continuous rotation rotator and claws made of HG70 high-strength steel, the grappler provides an unbreakable grip on logs of various sizes.

PRECISION HYDRAULIC SYSTEM

Our advanced dual-pump hydraulic system ensures that the boom movement and grapple operation are synchronized and smooth, reducing loading time by up to 30%.

ALL-TERRAIN DURABILITY

Designed with reinforced structural components and weather-resistant coatings, this crane excels in high-humidity rainforests and extreme cold logging sites.

FREQUENTLY ASKED QUESTIONS ABOUT LOG CRANES

Q: Can the wood grappler be replaced with other attachments?

A: Yes, our knuckle boom cranes feature a universal quick-coupling interface, allowing you to switch between a wood grappler, scrap metal grab, or a standard hook for versatile lifting.

Q: What is the benefit of a knuckle boom over a stiff boom for logging?

A: An articulated (knuckle boom) crane can reach over obstacles and has a much smaller footprint when folded. It is specifically designed for the high-frequency loading cycles required in the timber and waste industries.

Truck Mounted Crane FAQs

Q1: What is the main difference between a Telescopic Boom Crane and a Knuckle Boom Crane?

Answer: The choice depends on your specific operational needs:

  • Telescopic Boom Crane (Straight Boom): Features a wire-rope winch mechanism for precise vertical lifting. It is ideal for long-range reach, high-altitude hoisting, and projects where stability at height is critical, such as power grid maintenance or building construction.
  • Knuckle Boom Crane (Folding Boom): Features an articulated arm that can fold compactly behind the truck cab. It is designed for maximum versatility in tight spaces, loading/unloading cargo over obstacles, and allows more space on the truck bed for payloads. It is commonly used in logistics, waste management, and forestry.

Q2: How do I choose the right lifting capacity (tonnage) for my truck crane?

Answer: Choosing the correct tonnage requires considering two main factors: Max Load Weight and Working Radius.

  • A “10-ton crane” refers to its maximum lifting capacity at its shortest radius.
  • As the boom extends (working radius increases), the lifting capacity decreases.
  • For light-duty tasks (landscaping, signage), 2T-5T is sufficient.
  • For general construction and infrastructure, 6.3T-12T is the industry standard.
  • For heavy industrial use, mining, or machinery relocation, we recommend our 14T to 200T heavy-duty series.

Q3: Which truck chassis brands are compatible with your cranes?

Answer: We provide fully integrated solutions with world-renowned chassis brands to ensure global serviceability. Our cranes can be mounted on HOWO, Shacman, Dongfeng, Isuzu, Foton, and FAW chassis. Depending on the crane tonnage, we offer various drive configurations including 4×2, 6×2, 6×4, and 8×4 to comply with local road regulations and terrain requirements.

Q4: Can the crane trucks be customized for specific industrial applications?

Answer: Absolutely. We offer extensive customization options, including:

  • Hydraulic Attachments: Augers for drilling, grapples for timber or scrap, brick clamps, and aerial work baskets.
  • Remote Control: Optional proportional remote control systems for safer and more precise operations.
  • Chassis Reinforcement: Specialized sub-frames and heavy-duty outriggers for extreme lifting stability.
  • Tropical/Cold Climate Packages: Enhanced cooling systems or heaters for specialized environments.

Q5: What safety features are included in your crane-mounted trucks?

Answer: Safety is our top priority. All our units are equipped with:

  1. Load Moment Indicator (LMI): To prevent overloading beyond the rated capacity.
  2. Hydraulic Outriggers: Ensuring a stable footprint during lifting operations.
  3. Over-winding Alarm: To protect the wire rope and winch system.
  4. Emergency Stop Buttons: Located at all control stations for immediate shutdown.
  5. Anti-Corrosion High-Strength Steel: Ensuring structural integrity under extreme stress.

Q6: Why should I buy a complete crane-mounted truck unit instead of buying them separately?

Answer: Purchasing an integrated unit (Complete Unit) from us ensures that the crane and chassis are perfectly matched. We perform professional weight distribution calculations, sub-frame reinforcement, and comprehensive stability testing before delivery. A turn-key solution minimizes installation errors, ensures full warranty coverage, and makes the vehicle ready for work the moment it arrives at your site.
