Does a 5-ton spider crane have the same allowable lifting capacity with a jib as with the main boom?

The main boom’s allowable lifting capacity cannot be applied directly when a jib is fitted. The Onchtech 5-ton spider crane offers an optional hydraulic jib, but its allowable lifting capacity must be confirmed using the load chart that matches the crane model, jib installation and operating position.

What determines allowable lifting capacity with a jib?

In addition to the jib configuration and operating position, allowable lifting capacity is affected by:

• Main boom extension length
• Working radius
• Outrigger setup
• Lifting accessory configuration

The “5-ton” designation does not mean the crane can lift 5 tons at every position with the jib installed. Use the applicable jib load chart to confirm the allowable lifting capacity for the specified configuration and operating position.

What should buyers provide to confirm jib capacity?

When purchasing an Onchtech 5-ton spider crane with a hydraulic jib, provide:

• Load weight
• Target lifting height
• Horizontal distance

Obtain the jib load chart for the specified configuration rather than relying on the main boom’s allowable lifting capacity.
