The bucket thumb is an attachment that allows the
holding or clamping of objects between the bucket
and the thumb. The mechanical bucket thumb adds to
the versatility of the excavator, as it provides
grappling for long and awkward objects, can be
locked back up the excavator dipper arm when not in
use and does not impede the use of the excavator
bucket.
Bucket thumbs can be fitted to machines whether or
not they have a quickhitch fitted, and may be used
on multiple machines with the same mounting brackets
fitted.
There are no hydraulics or modifications required to
the existing excavator stick, and are available in
kit form for on-site assembly.
Performance Statement
High performance excavator mechanical bucket thumbs
from eiengineering will improve your
productivity and performance through:
Improved geometry for more efficient loading and
unloading of material
Heavy duty robust construction for increased
strength and durability
Serrated teeth for superior grab performance
Compact design folds up the dipper arm when not in
use
Flexibility – a number of widths available
Are designed to comply with OH&S requirements
What to look for in a Mechanical Bucket Thumb
Superior design for more efficient load management
Thumb width is matched to your application
Wear protection on thumb edges
High strength steel used in construction
Compact design and the ability to fold up the dipper
arm when not in use.
Adjustable length arms can have weak spots when
under load
eiengineering Mechanical Thumb Design
Our engineers calculate the proportions for the
materials being loaded with the lifting capacity of
the machine.
The serrated edge ensures that the load has a
minimum possibility of slippage
Compact design – thumb folds up the dipper arm when
not in use
Can be fitted to machines with or without
quickhitches
All
eiengineering
bucket thumbs are made from
Bisalloy, which is 3.1 times stronger than mild
steel. This ensures more strength and less weight
which means greater capacities, less fuel
consumption and less load on the excavator.
The Benefits
The benefits you will experience are:
Earn more money moving more material and different
material types
Reduce fuel costs – normally hard to load objects
require less time loading, carrying and unloading.
Increased safety as there is no need to balance
large loads on bucket edges
Save time – easier loading means less time behind
the controls, saving fuel and employee costs
Reduced servicing costs because the excavator is not
working as hard
Bisalloy construction means longer working life of
the attachment and less downtime carrying out
expensive repairs or modifications
What you get as standard
All of our bucket thumbs are delivered with serrated
edges and serrated bucket edges (if required) and
dipper arm bracket.
