The intended use of VAHVA grapples
A VAHVA grapple is a piece of equipment intended for loading and handling timber. The C and E
models of our VAHVA range are mounted suspended on a rotator, while the KC models are
mounted on an excavator with quick coupling. If the model type is E, the grapple is fitted with
spikes instead of jaws. The number after the letter E indicates the amount of spikes.
The maximum permissible load of the grapple denotes a load applied evenly on both jaws. See the
model-specific maximum load in the Technical Specifications table at the end of the manual.
When in use, the possible effect of torque on the structure must be taken into account.
The following accessories are available for the grapples:
-
Hose break valve: prevents the jaws from opening suddenly in the event of a hose break.
-
Pressure relief valve, if the max. working pressure of the hydraulic system of the machine
chassis is more than 250 bar. The warranty is valid only on the condition that the
manufacturer’s reference values are observed.
-
Load relief valve: ensures that the jaws are evenly opened, even under heavy loads, and
prevents the jaws opening suddenly in case of a hose break (KC36 E7 and KC42 E9).
-
Demolition jaws for the VAHVA KC36 E7 and the VAHVA KC42 E9 models.
-
Gravel jaws for the VAHVA C26 model.
