Working Range & Load Chart
This 3 ton spider crane features a scientifically optimized boom curve with multiple working radius configurations. The included load-radius diagram (load chart) shows safe lifting capacities at various boom angles and extensions — ensuring every lift is planned within safe operational limits.
Note: Actual working loads vary based on boom angle, extension length, and outrigger configuration. Always refer to the manufacturer's official load chart and operate within rated safety margins.
Dimensions & Transport
Length: 3550mm — fits in most standard freight containers and truck beds
Width: 955mm — narrower than many wheelbarrows, allowing passage through standard doorways (typically 1m wide)
Height: 1700mm — low enough for indoor ceiling clearance
These compact dimensions make the 3T spider crane one of the most transportable mini crawler cranes available, reducing logistics costs and enabling rapid deployment across multiple job sites.
Why Choose This 3 Ton Spider Crane?
1.Ideal for Space-Constrained Applications
Traditional truck-mounted or tower cranes cannot access narrow streets, indoor atriums, or rooftop installations. This compact spider crane solves that problem with its rubber crawler tracks and sub-1-meter width.
2.Dual-Fuel = Cost Savings & Versatility
The diesel + electric dual-fuel system means you can run on clean, quiet electric power indoors (no fumes, low noise) and switch to diesel outdoors for maximum performance. This flexibility reduces operating costs and expands your job site options.
3.Remote Control = Safety First
With 100m wireless remote control and 40ms ultra-fast response, operators can maintain safe distance from suspended loads, dangerous edges, or hazardous environments. The cyber proportional remote control option provides joystick-grade precision for delicate operations.
4.Proven Powertrain Reliability
The ChangChai CZ380G engine is a well-proven industrial diesel engine with 14.7kW power output, offering reliable starts, efficient fuel consumption, and easy worldwide parts availability.
