How the Small Spider Crane Works
- Power transmission system: The engine drives the hydraulic pump to extract oil from the tank and pressurize it, forming high-pressure hydraulic fluid. This fluid is delivered through hydraulic pipelines to each actuator. When the boom needs to extend or retract, the corresponding hydraulic valve directs the high-pressure oil into the boom cylinder, driving the piston’s movement.
- Execution mechanism: The 360-degree continuous rotation of the turntable is achieved through a hydraulic motor driving the slewing reducer. When the winch operates, the hydraulic motor drives the drum to wind the steel wire rope, enabling the lifting and lowering of heavy loads. The outriggers are raised and lowered by controlling the inflow and outflow of oil in their hydraulic cylinders.
- Integrated control system: Designed with 3D modeling, finite element analysis, and overall machine calculations, the system ensures high coordination and stability between components—this is why the small spider crane operates smoothly, reliably, and flexibly in diverse applications.
Advantages of the Small Spider Crane
- Excellent spatial adaptability: With a compact structure and a minimum width of less than 1 meter, it can easily pass through standard doorways. Whether for indoor work or underground projects where large cranes cannot enter, this small spider crane performs effortlessly and efficiently.
- Intelligent control system: It adopts both wireless remote control and onboard switch operation, featuring fast response and high precision. Operators can control it safely from a distance, enhancing safety while reducing manual effort and operational risks.
- Powerful drive configuration: Equipped with a hybrid diesel-electric power system that is both eco-friendly and economical, it adapts to various work environments. The hydraulic motor-driven walking system provides reliable traction, with a climbing ability of up to 36%.
Precision Design and Manufacturing Craftsmanship
- Optimized structural design: The boom adopts a five-section, pentagonal structure, which enhances bending strength and improves weight distribution. Through finite element analysis, the overall design ensures durability while reducing machine weight for easier maneuvering.
- High-quality materials and workmanship: Premium materials are carefully selected and processed with advanced manufacturing techniques. Every production step undergoes strict quality control, giving the mini tracked crawler crane exceptional durability and operational stability.
- Customizable production capability: The manufacturer supports customized solutions. From boom length to power systems, configurations can be tailored to meet unique working conditions—ensuring the machine perfectly matches each user’s operational needs.
