Delimbing grapples

This grapple is fitted with blades, which can be used for removing branches and producing clean limbed logs, by sliding it from the top to the stump, before the cut. Easy and quick. 

The delimbing grapples are a standard feature on professional tree shears.

See how the delimber works in video. 

CPR Rotator

Fast and limitless rotation device.

Suitable for tree shears and saw grapples, the CPR9 and CPR15 from Baltrotors enable the grapple rotation on excavators. The BA90 (Back Attachment 90°) on the grapple’s rear and the flat box are designed to be fitted with these rotators. 

New rotator adapter 140 mm

We now propose a new adapter model for rotators 140x140 mm / 4 bolts. 

In the center of the adapter is a bushing for hydraulic hoses. It can be fastened on Tree Shears, where is a standard flange ⌀173 mm, such as Biojack 180, Biojack 230, Biojack 300, Biojack 400S and Biojack 400 Combi.

The tree shears are always delivered with the correct adapter, so the rotator fastening is quick and easy. 

The adapter’s fastening flange to the rotator is the 140 mm bolt pattern. It’s securely fastened to the grapple’s standard flange.

Measures:

  • Fastening to the grapple: bolt pattern ⌀173 mm / 6 bolts
  • Fastening to the rotator: bolt pattern 140 x 140 mm / 4 bolts
  • Width 180 mm
  • Total height 95 mm

FELLING GRAPPLE 650S FOR EXCAVATORS

Saw grapple

⌀ 65 cm

 

 

The biggest saw grapple from Biojack, for forest harvesting, urban felling and wood handling. 

In municipal applications the grapple can be used, for instance, for removing trees around power lines and buildings. The trunk is cut with a chainsaw. During the loading cycle the saw remains in the frame and is activated by pressing a power button; this means that the grapple can be used flexibly for cutting and loading.
