A tracked mini crane, often called a small spider crane or spider crawler crane, is a compact lifting machine that moves on rubber tracks and stabilizes itself with four independent outrigger legs. It directly solves the problem of lifting, placing, and moving heavy loads inside buildings, narrow alleys, rooftop sites, and other restricted zones where large mobile cranes simply cannot enter. You no longer need to tear down walls, close large areas, or rely on risky manual handling. The rubber tracks protect finished floors, while the adjustable spider legs level the crane on slopes, stairs, or uneven ground. With lifting capacities from 3 to 8 tons and a narrow frame as slim as 980 mm, these machines bring true crane capability into confined spaces.

Main Components of a Spider Crane
Every spider crawler crane depends on a set of key components that work together for safe, precise lifting. Here are the main parts you will find on a YG machine:
- Tracked undercarriage: The rubber tracks spread the machine weight evenly. You can drive over sensitive floors or soft ground with very low ground pressure.
- Telescopic boom: A 5-section pentagonal boom gives you both strength and light weight. It extends and retracts quickly so you can adjust the reach while working.
- Spider outriggers: Four legs extend outward and adjust independently. This design keeps the crane level on slopes, stairs, or rough terrain.
- Winch and hoisting system: A high-speed winch and durable wire rope provide smooth, controlled hook movement for placing delicate loads.
- Slew system: A full 360-degree continuous rotation system allows you to swing the load without moving the crane body.
- Control system: Manual controls come as standard. An optional wireless remote control lets the operator stand at a safe distance with a clear view.
Mini Crane vs. Traditional Crane
When you compare a small spider crane with a conventional mobile crane, the right choice depends on your site access and ground conditions. The table below shows the most important differences.
| Feature | Mini Spider Crane | Traditional Mobile Crane |
| Access width | As narrow as 980 mm | Usually 2,500 mm or wider |
| Setup surface | Works on slopes, soft ground, or finished floors | Needs firm, flat, well-compacted ground |
| Outrigger adjustment | Four independent spider legs adjust separately | Standard outriggers, limited individual stroke |
| Indoor operation | Purpose-built for low-headroom, emission-sensitive sites | Often impossible due to height and exhaust |
| Transport | Light truck or standard trailer; some models fit in elevators | Requires heavy haulage and special permits |
| Lifting capacity range | 3–8 t (ideal for precise placement) | Often starts from 25 t upward |
| Operating cost | Lower fuel consumption, single-operator setup | Higher fuel use, larger crew, more permits |
In short, a traditional crane handles heavy lifting over open, solid ground. When you face a narrow doorway, a fragile floor, or a rooftop job, a tracked mini crane becomes the more practical tool.
Applications of Mini Spider Cranes
A small spider crane reaches places where bigger machines simply have no access. Common job site examples include:
- Glass and glazing work: Lifting large glass panels through narrow openings inside malls or atriums.
- Steel erection in tight spaces: Placing steel beams inside existing factories with low ceilings.
- Rooftop HVAC installation: Setting air-handling units on high roofs without closing the street below.
- Interior demolition and renovation: Moving materials through standard doors while protecting the floor.
- Landscaping and tree care: Carrying heavy stones or logs on soft paths without leaving deep tracks.
- Historic building restoration: Working inside sensitive structures that cannot handle heavy vibration.

Frequently Asked Questions About Mini Spider Cranes
A tracked mini crane (also called a spider crane) is a compact crawler crane with spider-type outriggers. It travels on rubber tracks and fits through narrow passages. You can set it up on uneven ground and lift loads up to 8 tons with a YG model. Its main purpose is to bring crane performance into spaces where conventional cranes are too large.
Yes. The rubber tracks distribute the machine weight over a large area, and the spider outriggers transfer the load onto stable pads or mats. This setup works well on grass, gravel, and even tiled floors when you use protective mats under the legs.
Yes. Every YG mini spider crane model offers an optional wireless remote control. The remote allows you to operate the boom, winch, and slewing from a distance, which increases both safety and visibility on the job site.
The YG-3 model weighs only 2,700 kg and fits easily on a small trailer. Even the 8-ton YG-8 travels on a standard 5,000 mm flatbed truck. The narrow width and low overall height often remove the need for wide-load permits.
Both terms generally describe the same type of machine. “Mini crawler crane” focuses on the tracked undercarriage, while “spider crane” highlights the four independent outrigger legs. In daily use, people use both names to refer to a compact tracked crane with spider-style stabilizers.
