A spider crane for sale features a compact crawler chassis, extendable outriggers, and a telescopic boom. Its narrow body allows access through restricted entrances, while adjustable boom length and angle provide flexibility when positioning loads at different heights and distances. YG Machinery offers 3-ton, 5-ton, and 8-ton spider cranes for different lifting tasks. Buyers can request current prices, confirm production lead times, and discuss delivery arrangements directly with the factory.

Spider Crane Lifting Capacity at Different Working Distances
Spider crane lifting capacity changes with working distance, boom extension, and boom angle. A crane can lift heavier loads close to its chassis but has lower capacity when its boom extends farther.
Before lifting, consider three factors:
- Working distance: Measure horizontal distance from the crane’s slewing center to the load.
- Boom position: Boom length and angle affect permitted load weight and hook position.
- Load chart: Confirm rated capacity for the planned lifting configuration.
For glass installation beside a building, each panel may require a different boom position. Operators must follow the load chart throughout the job rather than rely on nominal crane tonnage alone.
Spider Crane Size and Access Requirements
A mini spider crane can enter spaces that restrict larger lifting equipment. However, chassis dimensions alone do not determine whether a machine can reach the work area.
Measure doorways, corridors, turns, and floor transitions along the access route. Allow extra space for outriggers, which extend beyond the chassis during lifting.
Ground conditions also matter. Indoor floors, paved surfaces, and compacted soil have different load-bearing capacities. Each surface must support machine weight and lifting forces. A site assessment may be necessary when ground strength remains uncertain.
A crawler spider crane uses hydraulic motors to drive its tracks. This system allows controlled travel across suitable work areas. Operators must follow manufacturer limits for gradients, ground conditions, and machine movement.
Boom Reach and Lifting Height for Different Jobs
Boom reach determines horizontal access, while lifting height indicates whether a crane can reach the required position.
- Glass installation: Account for facade height, distance from the building, and obstacles such as scaffolding.
- Indoor machinery installation: Measure ceiling clearance and distance from the crane to the equipment foundation.
- Steel structure assembly: Confirm required lifting height and working distance for each component.
- Building maintenance: Plan boom movements around roofs, walls, and nearby structures.
A telescopic boom changes length, a luffing system adjusts its angle, and a slewing system rotates the crane. Operators must coordinate these movements when positioning loads.
Spider Crane Controls and Outrigger Stability
Listed models use manual operation, with remote control available as an option. A spider crane with remote control allows operators to control supported functions from a separate position. This arrangement can improve visibility during certain lifting tasks.
Before operation, inspect the hook, wire rope, controls, and safety devices. Deploy outriggers on stable ground and keep personnel clear of suspended loads.
The 5-ton model can include a torque display, an emergency stop button on its remote control, anti-overturning protection, and an outrigger warning function. Available features depend on the confirmed order configuration.

YG Machinery also provides export coordination, product information, and after-sales support for overseas customers. Contact the factory for model prices, availability, and delivery arrangements.
FAQ
When does a spider crane need a fly jib?
A fly jib serves as an auxiliary lifting attachment. It can provide access to certain lifting angles beyond the standard boom’s range. Requirements depend on load position and nearby obstacles.
How many cylinders and strokes does the standard EV80 engine on the 3-ton spider crane have?
The standard EV80 engine has two cylinders and uses a four-stroke design.
What does a torque limiter do?
A torque limiter displays boom extension height, boom angle, and load weight, helping operators monitor lifting conditions.
What safety systems are available for the 5-ton spider crane?
Options include a torque display, remote-control emergency stop button, anti-overturning protection, and an outrigger warning function. This warning system alerts operators when outriggers experience uneven loading.
Can buyers customize crane color or select a Euro V or EPA engine?
Yes. Buyers can request custom colors and alternative engine options where available. Engine selection depends on model availability and applicable requirements in the destination market.
