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 jaws' high-strength steel reduces the grapple weight.
  • 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 Outokumpu Metalli factory in Finland.
  • Strong quality: robotic welded frames and jaws, machined peg lines, factory-made cylinders, 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 HD (Heavy Duty) models for particularly challenging applications. In the jaws of the HD models, the side plates and the jaw tips are thicker than in the standard model. 

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