Product Details
U shaped main boom :
1. Our ingeniously engineered U-shaped arm utilizes an optimized multi-section arc arm system. With its large cross-sectional modulus, this arm boasts an impressive bearing capacity and exceptional stability. It significantly decreases the crane's weight without compromising on strength, fulfilling the demands for a lightweight design.
2. The U-shaped arm is not only user-friendly but also extraordinarily adaptable to various performance needs and working conditions. Its sleek and stylish design beautifully embodies our commitment to safety, environmental consciousness, and reliability. This arm is lighter, safer, more upscale, environmentally friendlier, and functionally superior.
Rope release method:
Our product offers two versatile rope release methods: inner rope out and outer rope out, crafted meticulously to cater to customer specifications.
Before utilizing the crane, a thorough inspection of the steel wire rope's clamp is vital. Ensure the clamp secures the wire rope effectively and that the rope is properly grooved. If the wire rope is twisted, creased, or shows signs of wear, severe corrosion, more than 10% breakage, a diameter reduction exceeding 7%, or discoloration from overheating, it requires replacement.
Hydraulic Oil Cylinder:
The powerful extension and retraction of the on-board crane are primarily driven by the hydraulic oil cylinder's actions.
We offer both single cylinder and double cylinder configurations to suit diverse operational needs.
A strategically placed balance valve between the telescopic rods ensures systematic boom extension and retraction.
The cylinder barrel's raw materials undergo quenching and tempering, achieving remarkable tensile strength.
Our piston rod is fortified through quenching and tempering, then coated with hard chromium, enhancing its rust-proof and wear-resistant properties.
Sealing components adhere to high standards, perfectly suited to the host machine's operational environment.
High Quality Slewing Support:
Known as the 'joints of machines,' our rotary bearings are indispensable for seamless operation.
For small tonnage truck-mounted cranes, we utilize integrated slewing supports, while large tonnage cranes benefit from split slewing supports.
Our crane's remarkable 360° infinite rotation capability enhances its versatility and operational efficiency.
Rear outrigger :
Choose from three robust rear outrigger forms: fixed, single cavity, or double cavity, tailored to your specific operational needs.
Customers have the flexibility to select the ideal rear leg configuration to meet their particular requirements.
