Order the bucket and thumb as one geometry
The JT01 assembly supplies the bucket and gripping structure together. Keep 350 or 400 mm width on the quote alongside the mounting and 900 mm jaw opening. This is a different purchase from welding a standalone thumb onto an existing stick.
Separate cylinder thrust from lifted load
The 2.9–4.9 t figure describes cylinder thrust. Lifted load is defined by the excavator lift chart at the working radius, with the 156 kg assembly and mounting included.
350 mm and 400 mm are complete bucket-width selections
| Component | Model selection |
|---|---|
| Bucket | 350 or 400 mm width; 900 mm opening |
| Mount | Upper pin-on or coupler pickup geometry |
| Gripping | Cylinder and 25–35 L/min / 90–150 bar circuit |
| Wear | Bucket tooth system, thumb pivots and cylinder seals |
Cleanup uses the bucket and gripping section together
Close the gripping section against the bucket to collect branches, stones or irregular objects, then place the load at the receiving pile. The integrated assembly keeps the bucket and thumb geometry together; the standalone JT02 follows an existing bucket instead.

JIANGTU JT01 thumb bucket Buying Questions
Is JT01 a standalone bolt-on thumb?
The JT01 configuration on this page is the supplier’s complete thumb bucket. A standalone thumb requires a separate stick or main-pin mounting design.
Does cylinder thrust define lifting capacity?
No. Thrust describes the cylinder’s force; the excavator’s load geometry and lift chart define the lifted combination.
Which widths can be specified for JT01?
The model column gives 350 and 400 mm bucket choices.
Which parts are replenished with the bucket assembly?
Selected tooth/retaining sets, thumb/bucket pivot pins and bushes, cylinder seals and hose ends.
