Premier Manufacturer of Compact 14t 14000kg Knuckle Boom and Stiff Boom Lift Cranes
Our cranes feature an innovative design using multiple hydraulic cylinders, creating a joint-like suspension mechanism. This advanced engineering allows for quicker action and maximizes efficiency, ensuring seamless operation in various settings.
Premier Manufacturer of Compact 14t 14000kg Knuckle Boom and Stiff Boom Lift Cranes Expertly crafted for confined spaces, our folding arm cranes excel in narrow environments like factory warehouses. Their structural efficiency contrasts with straight arms that require more deployment space, making them perfect for tight settings.
Premier Manufacturer of Compact 14t 14000kg Knuckle Boom and Stiff Boom Lift Cranes Our cranes are versatile with the ability to accommodate a wide array of accessories.
Premier Manufacturer of Compact 14t 14000kg Knuckle Boom and Stiff Boom Lift Cranes Equipped with a sophisticated hydraulic cylinder device, our cranes mimic the flexibility of an articulated arm manipulator. They can be fitted with auxiliary tools such as work platforms, buckets, fixtures, hanging baskets, plate forks, various grippers, spiral drills, tire loading manipulators, and pile pullers. Unlike straight arms with their constrained soft steel wire at the tip, these cranes offer unparalleled versatility.
Premier Manufacturer of Compact 14t 14000kg Knuckle Boom and Stiff Boom Lift Cranes Our state-of-the-art design ensures minimal space occupancy on the vehicle, enhancing operational efficiency.
In terms of spatial efficiency, our cranes stand out with their compact footprint, ensuring optimal use of available space. Premier Manufacturer of Compact 14t 14000kg Knuckle Boom and Stiff Boom Lift Cranes With the ability to fully retract the crane arm during transport, our design minimizes space usage significantly. In contrast, straight arm truck-mounted cranes require horizontal placement, taking up substantially more space during vehicle operation.
Product Details
U-Shaped Main Boom:
1. The ingeniously designed U-shaped arm boasts an optimized multi-section arc arm system. This design offers a pronounced cross-sectional modulus, ensuring robust load-bearing capacity combined with exceptional stability. Notably, this innovation significantly reduces the crane's weight while maintaining its impressive load-bearing prowess, perfectly aligning with the industry's demand for lightweight solutions.
2. The U-shaped arm is not only user-friendly but also exhibits remarkable adaptability across various performance metrics and operational conditions. Its sleek and stylish appearance beautifully embodies the core principles of production, emphasizing safety, environmental consciousness, and reliability. This novel arm design brings a host of advantages: it's lighter, safer, more sophisticated, eco-friendly, and functionally versatile.
Rope Release Method:
Our crane offers dual methods for rope release: the inner rope out and the outer rope out, tailored precisely according to customer specifications.
Prior to crane operation, a thorough inspection of the steel wire rope's clamp is essential. Begin by verifying the secure fixation of the rope clamp and ensuring the steel wire rope is properly seated in the groove. Should the steel wire rope exhibit twisting, creasing, excessive wear, severe corrosion, a breakage rate exceeding 10%, a diameter reduction of over 7%, or discoloration from overheating, it is imperative to replace the steel wire rope immediately.
Hydraulic Oil Cylinder:
The extraordinary extension and bending capabilities of the on-board crane are primarily driven by the dynamic action of the oil cylinder.
Our systems feature both single-cylinder and double-cylinder oil configurations.
A precision-engineered balance valve is positioned between the telescopic rods, ensuring a seamless and orderly boom extension and contraction sequence.
The oil cylinder barrel is crafted from materials that undergo rigorous quenching and tempering, endowing them with exceptional tensile strength.
The piston rod, undergoing quenching and tempering, is further fortified with a hard chromium coating on its outer surface, significantly enhancing its resistance to rust and abrasion.
Our sealing components are engineered to the highest standards, perfectly attuned to the demanding operating conditions of the host machine.
High-Quality Slewing Support:
Revered as the 'joints of machines,' rotary bearings are integral to our crane’s performance.
For varying crane sizes, we employ integrated slewing supports for small tonnage truck-mounted cranes, and split slewing supports for their larger counterparts.
Our advanced crane mechanism allows for infinite 360° rotation.
Rear Outrigger:
We offer three distinctive rear outrigger configurations: fixed, single cavity, and double cavity.
Customers are empowered to choose the rear leg configuration that best aligns with their specific operational needs.
