C models

User-friendly and durable VAHVA C-series grapples

NEW DESIGN

The frame has been designed to be bended and symmetric, keeping stresses under better control.
The cylinder uses both jaws, and the reaction bars stabilise the movement, making the movement of the grapple jaws more balanced and symmetrical.
The tips of the jaws get into the pile at an optimal angle and grab a full load when they close.
Wider jaws and jigs on the side plates of the jaws help to align all of the timber in a bundle.

MODERN MANUFACTURING TECHNOLOGY

The grapples are manufactured at the Outokummun Metalli factory in Finland.
Strong quality: high-strength steel as material, robotic welding, machined peg lines, bronze bearings, powder coating.
Hardened and ground, dimensionally precise pivot pins with welded locking plates.
Two reaction links made from high-strength steel have been fitted with welded sleeves with slide bearing.

EASY MAINTENANCE

Quick and safe greasing in one position while the grapple is closed and lowered to the ground.
In the C-line, three different sizes of cylinders and seal kits are used, helping with the management of spare parts.

EVEN STRONGER HD-MODELS

The C line also includes three HD (Heavy Duty) models: C36HD, C46HD, and C60HD. The frame and jaws of the HD models are designed for particularly challenging applications. Compared to the basic models there is e.g. a thicker cover plate and thicker side plates with longer welds in the frame of the HD models.

Several updates has been launched to the VAHVA range in September 2018. Read more about the product redesign (pdf).
