Overview
Mini crawler (spider) cranes of the YG series are designed for confined indoor, rooftop and restricted-access lifts where standard boom cranes cannot operate. Models cover lifting capacities from 3 t to 8 t and have compact transport dimensions to pass through single doors and freight elevators. Dual-power (diesel + electric) configurations and wireless remote controls enable low-emission indoor operation and reduced site labour.

Key Uses

• Glass curtain-wall and panel installation using vacuum handling systems
• Indoor, underground and confined-space lifts where narrow clearances and low floor loads prevent conventional cranes
• Steel structure and rooftop installation where machine weight and compact transportability are critical
• Maintenance in municipal, airport and high-foot-traffic public zones requiring fast deployment and small footprint

Available Models Mentioned

• YG-3 — 3 t
• YG-5 — 5 t
• YG-8 — 8 t

Configurations & Options

• Power systems: standard dual-power (diesel + electric); optional region-specific engines and motor wiring for local voltage/frequency
• Accessories: auxiliary fly jibs (approx. 2–5 m) and work baskets (1.35 m or 1.8 m)
• Safety & controls: torque limiters with LCD displays, anti-tilt alarms, emergency stop, intelligent load/radius monitoring and wireless remote operation
• Operation modes: manual operation and manual walking standard; remote control and operator cabin options available on larger models

Shipping & Packaging Notes
3‑ton units are commonly stocked and can be containerized efficiently: roughly 5–6 crated YG-3 units per 40HQ; fewer units fit per container for 5‑ton and larger classes.

Production & Lead Time
Standard 3‑ton models are often available for immediate dispatch. 5‑ton, 8‑ton and customised or painted units typically require a short production lead time (example: 5–7 days for some non-stock variants).

Parameters Summary

• YG-3: Capacity 3 t; Max working radius 8.83 m × 0.15–0.2 t; Max lifting height 9.9 m × 0.7 t; Winch speed 0–8 m/min (4-rope); Rope φ8 mm × 45 m; Boom 5-section pentagonal; Boom length 3.1–9.2 m / 20 s; Boom angle 0°–78° / 13 s; Slew 0–360° continuous / 60 s; Walking drive hydraulic / 0–2.5 km/h; Gradeability (25°) 36%; Transport 2950 × 980 × 1560 mm; Deadweight ~2,700 kg
• YG-5: Capacity 5 t; Max working radius 14 m × 0.5 t; Max lifting height 16.8 m; Winch speed 12 m/min (4-rope); Rope Φ11 mm × 80 m; Boom 5-section pentagonal; Boom length 12.3 m / 54 s; Boom angle 0°–78° / 13 s; Slew 0–360° continuous / 38 s; Walking drive hydraulic / 0–2.5 km/h; Transport 5000 × 1500 × 1900 mm; Deadweight ~6,200 kg
• YG-8: Capacity 8 t; Max working radius 16.5 m; Max lifting height 18 m; Winch speed 12 m/min (4-rope); Rope Φ11 mm × 80 m; Boom 5-section pentagonal; Boom length 12.3 m / 54 s; Boom angle 0°–78° / 13 s; Slew 0–360° continuous / 38 s; Walking drive hydraulic / 0–2.5 km/h; Transport 5000 × 1600 × 2180 mm; Deadweight ~7,200 kg

Real Field Case
A 3‑ton dual‑power mini crawler solved an indoor lifting constraint where passage widths were ~1.1 m and floor loads were restricted. Electric plug‑in operation enabled zero‑emission indoor lifts, remote control reduced site labour and a fly jib allowed faster placement than larger crane alternatives. The case also highlights containerization efficiency for 3‑ton units.

FAQs

• Crate & container guidance: crated YG-3 gross ≈ 3,200 kg; a 40HQ can fit roughly 5–6 YG‑3 units or about 2 YG‑5 units (illustrative)
• Safety systems: emergency stop, anti-tilt warnings, torque limiters with radius/load display and outrigger pressure alarms
• Lead time: stocked 3‑ton units common; 5–8 t and customised variants typically need several days
