A small tracked crane is a compact lifting machine on rubber tracks, named after its four outriggers that extend like spider legs to create a stable base on uneven ground. A small tracked crane typically lifts 3 to 8 tonnes, but its real advantage is fitting through standard doorways (just 980 mm wide for the YG-3), riding passenger elevators, and working on rooftops. If you handle indoor renovation, glass installation, bridge inspection, or plant maintenance, this machine solves access problems that ordinary cranes cannot.
Mini Tracked Crane vs Conventional Lifting Methods
1. Access – fits where nothing else does
Conventional truck cranes or wheeled mini cranes need wide roads, large turning circles, and big stabilizer footprints — they cannot enter standard doorways or work inside buildings. A mini tracked crane, however, squeezes through a 980 mm wide doorway (YG-3 model), travels indoors, climbs stairs step by step on rubber tracks, and even rides a passenger elevator to upper floors. For rooftop projects or retrofit work, this access advantage alone saves weeks of disassembly and manual rigging.
2. Surface protection – no damage to finished floors
Wheeled cranes concentrate weight on small contact points, leaving marks, scratches, or dents on marble, polished concrete, tiles, or hospital floors — often requiring plywood or steel plates for protection. In contrast, the machine uses rubber tracks that spread weight over a large area, creating extremely low ground pressure. You can drive it across marble lobbies, hospital hallways, freshly laid tiles, or data center raised floors without leaving a trace. No mats, no extra labor — just drive and lift.
3. Control and safety – wireless remote vs. cab operation
Cab-operated cranes force the operator to view the load from a distance, often with obstructed sightlines, relying on hand signals or radios, which increases communication errors and accident risks. This small tracked crane comes standard with a wireless remote, allowing the operator to stand exactly where the load needs to be placed — next to a fragile glass panel, near a rooftop HVAC unit, or inside a tight mechanical room. Proportional controls let you creep the load at millimeters per second, dramatically reducing accidental swings and impacts.
4. Setup time – under one minute vs. hours of rigging
Assembling a gantry crane takes hours; a boom lift requires truck delivery, outrigger pads, and manual leveling; wheeled cranes need outrigger extensions and cribbing. Roll a mini tracked crane into position, and with a single button push, its outriggers extend horizontally then vertically to lift the tracks off the ground. It auto-levels on slopes up to 25 degrees. The entire process takes less than 60 seconds — no tools, no cribbing, no extra crew. Compare that to waiting for a gantry or boom lift to arrive and set up.

FAQ about Mobile Spider Crane
Yes. The rubber tracks and hydraulic drive allow it to climb standard stairs step by step. Always check the step height against the machine’s ground clearance.
Typically, a 50–100-meter line-of-sight. You can stand safely away from the load while still having full control.
Yes, the electrical system is weather-sealed. However, avoid submerging or using it in extreme storms. Ground conditions should be firm.
Keep them clean of sharp debris, check tension monthly, and replace when worn. YG Machinery stocks replacement tracks and parts.
Yes. YG tracked spider cranes can travel with approximately 30% of their rated load. This is very useful for repositioning heavy objects without re-rigging.
