SP 761 LF

Compact and heavy duty all-rounder.

The SP 761 LF is a compact, heavy duty and high performance harvester head. It is designed according to SP´s Low Friction principle for minimum friction and maximum productivity. The SP 761 LF is suited for working on both large wheel based harvesters as well as tracked harvesters and excavator carriers. The high capacity in combination with the compact, protected and heavy duty design makes the SP 761 LF able to handle a variety of different demanding harvesting applications with great performance. Regardless if the task at hand is in large diameter soft wood, crooked and limby hardwood or dense mixed wood stands you can count on the SP 761 LF to get the job done. Equipped with the specially designed processing knives and a topping saw the SP 761 LF becomes a dedicated processing head with great performance processing decked wood out of a pile. The SP 761 LF truly is a compact and heavy duty all-rounder. The SP 761 LF reaches top performance in stands with a diameter of 20 to 56 cm, but is thanks to the LF principle also capable of efficiently working larger tree sizes. SP 761 LF can be used with virtually all control systems on the market. Through a simple adaptation the SP 761 LF can be used together with the following systems: Dasa280, Dasa380, Dasa4, Dasa4 Compact, Dasa Forester, John Deere Timbermatic, Motomit IT, Motomit PC, Komatsu MAXI, Ponsse Opti, Technion, Techno Matic, TOC-MD.

Description

Knife Design

The delimbing knives are cast in high-strength steel and equipped with long cutting edges. This means that the limbs are cut off instead of being broken off. This minimizes friction during delimbing and allows the trunk to be fed through easily.

Feed rollers:

This smart solution means that when the harvester head is fully open, i.e. at maximum tree size, the feed rollers are at their greatest angle and provide maximum carrying force against the trunk. As the feed rollers carry the trunk, the pressure on the delimbing knives can be reduced, which means less friction and the harvester head can feed the trunk through quickly and easily..

Proportional pressure

Proportional pressure ensures that the harvester head automatically works at the correct pressure in relation to tree diameter. This means that the friction between the trunk and harvester head is minimized and that the harvester head run at peak efficiency. Individual settings per tree species maximises production further.

LogHold

LogHold is an evolution of proportional pressure and means that the delimbing knife pressure against the trunk can be reduced, without the risk of the trunk being dropped. If the trunk is about to fall, LogHold regulates the knife pressure so that the trunk is held in the right position. The amount by which the diameter may increase before LogHold takes action is set in the control system. No additional sensors are required.

Extra equipment

• Color marking: Used to optimize forwarding work when the assortments are difficult to distinguish by sight alone.
• Multi-tree handling: Optional equipment for heightened production when working with small-diameter stands as SP’s multi-tree handling enables you to fell and accumulate several stems to be processed together.
• Find end function: With the aid of a sensor mounted in the saw unit housing, the head automatically locates the end of the stem at the push of a button.
• Roller motors: Different size roller motors are available to optimize the head’s performance depending on working conditions and base machine size. Choose between two fixed displacements, 750 cc and 820 cc, and the multi-speed feed presented below.
• Light for saw unit housing: An LED lamp in the saw unit housing offers additional illumination of the work area.

• Eucalyptus kit: Debarking kit for eucalyptus trees.
• Feed rollers: Several different feed roller models and variants are available to suit different conditions and needs.
• Measuring system integration: SP harvester heads can be used together with essentially any measuring system on the market. This means lower investment costs and a quicker startup as the operator need not learn a new system.
• Dasa5 complete measuring system: A complete measuring system is required if mounting the head on, say, an excavator or a tracked harvester.
