Construction sites with limited access need a crane that fits through standard doorways yet lifts heavy loads. A crawler spider crane does exactly that. Its compact body and extendable outriggers deliver stable lifting power in confined areas. The YG series features a 360-degree continuous rotation system and a telescopic U-shaped boom. Three models cover lifting needs from 3 to 8 tons. These machines are widely used for glass installation, HVAC placement, and steel assembly in urban construction. This guide walks you through specifications, working principles, key advantages, and real project applications.
Crawler Spider Crane Product Specifications
The specifications listed above are for our standard 3T, 5T, and 8T spider crane models. If you require other capacities or customized configurations, please contact us for professional recommendations and solutions.
The crawler spider crane gets its name from the outrigger layout. Four extendable legs spread out like spider legs for stability. The crawler track base allows the machine to move on its own across uneven ground.
The working process follows these steps:
Position the crane at the work site using the crawler tracks
Extend the outriggers to create a wide and stable base
Adjust each leg independently for level positioning on slopes
Extend the telescopic boom to the required length
Rotate 360 degrees to place the load at the exact position
The 5-section U-shaped boom provides an excellent strength-to-weight ratio. Each section slides smoothly during extension and retraction. The hydraulic system controls all movements with precision. Operators use a wireless remote or cabin controls depending on the model.
Safety features are built into every YG crawler spider crane. Load moment indicators prevent overload situations. Anti-two-block systems protect the wire rope and hook assembly. Emergency stop buttons are located on both the remote and the crane body. These features ensure safe operation in busy work environments.
The hydraulic system uses high-quality seals and hoses rated for continuous duty. Regular oil changes and filter replacements keep the system running smoothly. YG designs each hydraulic circuit for easy access during routine maintenance checks.
Crawler spider cranes serve many industries where space is limited but lifting power is essential.
Glass and curtain wall installation — The compact design allows work inside building atriums. The precise hydraulic controls position glass panels accurately.
HVAC and equipment placement — Rooftop units and chillers need precise placement in tight mechanical rooms. The crane lifts heavy equipment through narrow access paths. This reduces reliance on multiple workers and manual rigging.
Steel structure assembly — Small to medium steel beams require accurate positioning. The 360-degree rotation speeds up assembly work significantly. Operators can swing the load between pickup and placement points without repositioning the crane.
Interior renovation projects — Material handling inside existing structures benefits from the crane footprint. Floor loading limits are easier to manage with the tracked base. The rubber tracks protect finished flooring surfaces from damage during movement.
Film and stage production — Mini spider cranes position lighting and camera equipment on indoor sets. The quiet hydraulic system works well in noise-sensitive venues.
Power plant maintenance — The YG-8T handles valve replacement and pipe lifts in congested plant areas. Its stability on industrial flooring makes it ideal for scheduled outages. Plant managers appreciate the quick mobilization time during emergency repairs.
Telecommunications tower work — The YG-5T lifts antenna sections and cable trays to elevated positions. Its outrigger spread provides stability on unpaved ground around tower bases.
Spider Crawler Crane FAQ
Can a spider crane work on slopes?
Yes. The independent outrigger legs adjust to different heights. The crawler tracks provide traction on mild inclines up to 15 degrees.
How fast can the boom extend?
The YG-3T extends its boom in 20 seconds. The YG-5T and YG-8T take 54 seconds for full extension.
Do I need a special license to operate it?
Requirements vary by country. Most regions require crane operator certification. YG provides an operation manual and video training for every unit.
What maintenance does the crane need?
Regular checks include hydraulic oil levels, track tension, and wire rope condition. YG recommends servicing every 500 working hours. Proper maintenance extends the crane’s lifespan significantly and reduces unexpected breakdown costs.
Can the crane be transported easily?
The YG-3T weighs 2700kg and fits on a standard flatbed trailer. The larger YG-5T and YG-8T may require heavy transport permits depending on your local regulations.
