How Does the 3 Ton Spider Crane Work?
The 3 ton spider crane operates through a simple hydraulic system. A diesel or electric power pack drives hydraulic pumps. These pumps send pressurized oil to cylinders and motors throughout the machine.
The operator controls all functions from a manual station or wireless remote. The controls manage boom extension, lifting, slewing, and walking. The remote option keeps the operator at a safe distance from the load.
Key components include:
- Five-section telescopic boom: Pentagonal structure for maximum strength
- Hydraulic winch: Handles lifting and lowering with precision
- Slew ring: Enables 360-degree continuous rotation
- Crawler tracks: Allow movement across various surfaces
- Outriggers: Provide stability during lifting operations
The crawler tracks and outriggers set up in minutes. The machine arrives on site, unfolds its legs, and levels itself. This quick deployment reduces waiting time and increases productivity.

What Makes the 3 Ton Spider Crane Stand Out?
Compact Transport Dimensions
The YG-3 folds to just 2950mm long and 980mm wide. This allows it to fit through standard single doorways. It travels on standard elevators. Access to indoor jobs and roof spaces becomes possible.
Extreme Maneuverability
Rubber tracks protect finished floors. Independent track motors enable sharp turns. The machine turns 360 degrees in its own footprint. This level of maneuverability is essential on crowded job sites.
Quick Setup and Breakdown
Smooth, vibration-free operation comes from the power pack design. Outriggers extend and level the machine quickly. Setup takes minutes, not hours. The telescopic boom extends to full height rapidly.
Operator Control Options
Manual controls provide direct feedback. Wireless remote control keeps the operator positioned safely away from the load. Both options offer precise control over all machine functions.
Low Ground Pressure
Rubber tracks distribute weight evenly. This minimizes impact on sensitive surfaces. The small spider crane operates on finished floors without damage. It works on grass, paving, and delicate landscaping.
Where Can You Use a Small Spider Crane?
High-Rise Construction
The 3 ton spider crane rides construction elevators to upper floors. It handles curtain wall installation, window fitting, and equipment placement. Its light weight protects the building structure.
Glass Installation
Glass panels require careful handling. The spider crane’s precision controls allow accurate positioning. This reduces the risk of breakage and installation delays.
Steel Structure Erection
Steel beams and columns need precise placement. The mobile spider crane reaches heights needed for structural work. Its compact design works around existing structures.
HVAC and MEP Installations
Heating and cooling equipment often sits on rooftops. The spider crane lifts units weighing several tons into place. It works where tower cranes cannot reach.
Plant Maintenance and Equipment Installation
Industrial plants need equipment relocation and maintenance. The spider crane moves through factory spaces. It lifts heavy machinery for installation or repair.
Infrastructure Projects
Bridge construction and tunnel work benefit from the spider crane’s abilities. Its compact size and reach handle these demanding applications.
