Designed purpose of use 

The AVANT Heavy duty timber grab is an attachment that is designed and manufactured to be used with 

AVANT multi-purpose loaders that are shown in Table 1. The Timber grab is intended for lifting and stacking 

of tree trunks, branches, or other similar materials. The rotating grab makes it possible to move materials 

sideways or parallel to the machine. 
The strong hydraulic grapple allows firm grip of lifted material. The hydraulically rotating grab makes it easy to 

drive on narrow areas, and to rotate the load into correct position for loading on a trailer or for stacking. The 

hydraulically operated rotation is selected with an electric switch, or a switch of the attachment control switch 

pack.  
Any straps, chains, or ropes must not be attached to the timber grab for lifting purposes. The Heavy duty 

timber grab is not designed for any other use than specified and must not be used for any other purposes than 

what is intended for. 

 

The attachment has been designed to require as little maintenance as possible. The operator can perform 

regular maintenance tasks. All repair work can’t be performed by the operator, and demanding repair and 

maintenance operations are to be left for professional maintenance. All maintenance work must be done using 

proper safety equipment. Spare parts must be identical with original specifications, which can be ensured by 

using only original spare parts. A separate spare parts catalogue may be available, consult your Avant dealer. 
Familiarise yourself with the manual's instructions regarding service and maintenance. Please contact your 

AVANT retailer if you have additional questions about the operation or maintenance of the equipment, or if 

you require spare parts or maintenance services.

It is recommended to use the attachment only with loaders marked with 

 in Table 1. When using with models 

marked with (

compatibility with a model not shown in table, contact your Avant dealer. 

 

Compatibility recommendations are based on the weight of the loader and available lifting capacity.
