Log Max 6000Twin

Log Max 6000Twin is a light-weight head suitable for “low branches” featuring a twin bottom knife for optimal delimbing from the lowest part of the trunk to the top. This head combines low weight with high power and is especially designed for large wheeled carriers.

 

The delimbing unit is composed of five movable knives with patented positioning to minimize friction losses and increase the active pulling force.The knives have wide cutting edges for handling thick branches, their shape assures good delimbing and minimized damage to the log.

 

The unique compound curve delimbing knife profile provides outstanding stem coverage and increased log quality.

 

Log Max 6000Twin can be equipped with Hultdins Supercut saw. Log Max 6000Twin is built on well tested hydraulics with a max hydraulic pressure of 260 bar (3,771 psi) and a max flow of 280 l/‌min (74 gpm).

FEED ROLLERS

v-steel rollers  

V-Steel

By placing the stud bars in angled rows, Log Max has obtained a self cleaning feed roller with very high pulling force both in forward and reverse, without risk of spinning.

v-steel aggr. rollers  

V-Steel Aggressive

The V-steel Aggressive roller has studs that sink deeper in the tree trunk.

eucalyptus rollers  

Eucalyptus

Log Max Eucalyptus rollers have angled edges for debarking as eucalyptus demands complete debarking when felling.

MULTI-STEMMING

  • cut stump

Accumulation kit

 

This allows the head to be used as a combination head - both as a conventional harvester as well as a multi-stemming head for thinning small wood or in late brush cuttings.

 

The Log Max Accumulation Kit can be run with Log Mate 500 (LM 402), Motomit, CabsWin, Dasa 380, Ponsse Opti, Timbermatic and Komatsu Maxi.
