A spider crawler crane combines a small footprint with serious lifting power. This machine fits through standard doorways and works in areas where large cranes cannot go. The YG series offers three models: YG‑3 (3 t), YG‑5 (5 t), and YG‑8 (8 t). Each model uses a 5‑section telescopic boom with a pentagonal structure for strength and reach. The boom extends from 3.1 m up to 9.2 m on the YG‑3, and reaches 12.3 m on the YG‑5 and YG‑8 models. Maximum working radius ranges from 8.83 m to 16.5 m depending on the model. The crane rotates a full 360°continuously. Hydraulic motors drive the tracks, giving a walking speed of 0–2.5 km/h. The machine climbs grades up to 25°(36 %). Manual operation comes standard, with a remote control option available.

Advantages of the Spider Crawler Crane
- Compact and Narrow:The YG‑3 is only 980 mm wide. This compact crane passes through doorways and moves along narrow corridors. It works inside buildings, on rooftops, and in crowded city streets.
- High Lifting Capacity for Its Size:Even this small crawler crane handles heavy loads – the YG‑8 lifts up to 8 tons. The 5‑section boom reaches 18 m high on the largest model. That gives you both power and height for many construction jobs.
- Stable and Safe to Operate:Hydraulic outriggers create a wide, firm base. The boom adjusts from 0° to 78°. You can run the machine manually or use the optional remote control, which keeps you at a safe distance during tricky lifts.
- Easy to Move Between Sites:Light weight and compact dimensions make this small tracked crane simple to transport. It fits on a standard trailer and sets up quickly. That saves time and cuts transport costs – a clear advantage if you plan to buy a mini crawler crane for sale.
Applications of Track Spider Crane
- Indoor Construction and Renovation:The narrow width lets the crane enter finished buildings. It lifts steel beams, HVAC units, and glass panels to upper floors. Ideal for office fit‑outs, shopping mall upgrades, and hospital expansions.
- Glass Curtain Wall Installation:Precision is critical when handling glass. This crawler crane offers smooth, accurate movements. The remote control allows careful positioning, reducing the risk of cracks or breakage.
- Bridge Maintenance and Repair:Rubber tracks protect bridge decks while providing excellent grip. The crane reaches over railings and works from the deck or underneath. Full 360° rotation gives access to every part of the structure.
- Factory Equipment Installation:Manufacturing plants often have tight aisles and low overhead clearance. This electric spider crane (or its diesel version) moves easily through those areas. It places heavy machinery, changes out parts, and supports maintenance without blocking production lines.
FAQ about the Track Spider Crane
Q1: What load capacities are available?
Three models: YG‑3 (3 t), YG‑5 (5 t), and YG‑8 (8 t). Choose according to your typical lift weight.
Q2: Can this crane work indoors?
Yes. Its slim width and rubber tracks make it floor‑friendly. Low noise and optional electric power (electric spider crane) allow quiet, emission‑free indoor use.
Q3: How does the remote control function?
The optional remote lets you control boom extension, rotation, lifting, and travel from a distance. It improves safety and visibility.
Q4: What maintenance is required?
Regular checks on hydraulic fluid, track tension, and wire rope are recommended. All components are standard and easy to service.
Q5: Does it handle uneven ground?
Yes. The crawler tracks provide good traction on dirt, gravel, and slopes. It climbs grades up to 25° without trouble.
