KC and K models

New models!  
Vahva KC models have been designed for use with excavators, and the line includes a suitable version for different size categories, and with different quick hitches. The grapples are used e.g. for handling wood, clearing plots, demolition, and pipeline projects.  

New features of the KC line

  •  HD jaws as standard (not in KC 30), with the side plates and piercing tip thicker than in the basic model. There is also an additional bar between the side plates for reinforcing the structure.
  • Quality quick coupling integrated into the frame, no secondary welding.
  • A lifting hook welded into the frame.
  • In the spike models (model marking: E), the tips close at the same level. This feature was designed particularly at the request of our clients who use excavators: the spikes pick up the material smoothly from the ground, without accumulating any excess soil. This feature also reduces the wear and tear of the tips.
  • The spikes of the E models have been manufactured from HARDOX 400 wear- and abrasion-resistant steel.
  • Threaded demolition jaws available as an accessory for the KC42 E9 model.

The new frame structure and other product improvements, as well as the improved manufacturing technique raise the KC line grapples to a whole new level of functionality and durability.

  • The frame has been designed to be circular and symmetrical, and the manufacturing process also includes bevelling, so the stresses directed at the frame can be handled better.
  • The cylinder uses both jaws, and the reaction bars stable the movement, making the movement of the grapple jaws smoother and more symmetrical.
  • The grapples are manufactured in Finland. Quality is ensured by e.g. robot-welded frames and jaws, machined pivot lines, cylinders manufactured on site, powder coating.

The smaller models, 15, and 21, belong to the older K line, which we have been manufacturing already for 10 years, so the grapples have been thoroughly tested in real working conditions.

Demolition jaws  
Separate threaded demolition jaws are available for the Vahva KC42 E9 grapple. This means that the grapple can be used in many ways, either with spikes or demolition jaws, depending on the work site. The weight of the demolition jaws is 336 kg, and the width (measurement F) is 980 mm.
