Product catalog summary

Overview: The document provides technical specifications and features of the Valmet 380 and 385 harvesting heads, designed for high production output in challenging forestry conditions. These heads are known for their robust construction, reliable hydraulics, and advanced control systems.

Dimensions:

Valmet 380: Width (arms closed) - 51" (1300 mm), Width (arms open) - 65" (1650 mm), Height - 90" (2286 mm), Weight - 4800 lbs (2177 kg).
Valmet 385: Width (arms closed) - 57" (1450 mm), Width (arms open) - 75" (1900 mm), Height - 106" (2692 mm), Weight - 6300 lbs (2858 kg).

Felling and Cutting: Both models feature a hydraulically driven chain saw. The 380 uses a .404” 18H main saw bar with a maximum cut diameter of 29.5” (750 mm), while the 385 offers an optional 3/4” chain and a top saw with a maximum cut diameter of 16” (410 mm).

Feeding:

Valmet 380: Equipped with Black Bruin Motors, 940 cc standard motor size, max feed speed of 15 ft/sec (4.57 m/sec), and max feed force of 6500 lbf (29 kN).
Valmet 385: Uses Poclain MS11 motors, 1147 cc motor size, max feed speed of 14.5 ft/sec (4.4 m/sec), and max feed force of 7350 lbf (33 kN).

Delimbing: Both models feature floating front/top knives, four delimbing arms, and proportional delimb pressure with a max knife opening of 28” (710 mm).

Control & Measuring System: Controlled by MaxiHead, providing accurate measuring, complete harvest data, and onboard diagnostics.

Hydraulic Requirements: Pressure ranges from 3625-4640 psi (250-320 bar) with a flow of 65-110 gpm (250-425 L/min).

Optional Equipment: Includes feed roller options and photo optic sensors for increased accuracy and efficiency.

Additional Features:

Durable delimbing knives made of abrasion-resistant steel.
Heavy-duty frame and main pin assembly to minimize stress points.
Auto cut control to minimize snags and damage.
Proportional knife pressure to maximize harvest efficiency.

Conclusion: The Valmet 380 and 385 heads are engineered for durability and efficiency, suitable for various timber types, including heavy timber and hardwoods. They offer advanced features for precise processing and are supported by a robust hydraulic system.
