Technical Field
[0001] This disclosure relates to the field of tools for crushing and/or cutting material
and more particularly to the frames of the tools having jaw sets.
Background
[0002] A device for crushing and/ or cutting material is generally known. The device may
have a jaw set for example suitable for crushing concrete. A different jaw set may
be used for crushing or cutting other materials, for example for cutting scrap iron
and/or iron sections. Thus, different devices may be used for crushing or cutting
different materials. The jaw sets may be interchangeable in order to be used for varying
work requirements. Each jaw set may be supported by a frame that is connectable to
a machine arm. The frame may be rotatable relative to the machine arm.
[0003] EP2578752 discloses a demolition apparatus and an adapter frame of the demolition apparatus.
The demolition apparatus may have a jaw set having a first jaw and a second jaw. The
first jaw may be pivotably coupled to the second jaw. The second jaw may be pivotable
about the pivot pin. The adapter frame may be formed with coupling seats that engage
the ends of the pivot pin on the jaw set to assemble the demolition apparatus. The
demolition apparatus may be rotatable relative to a machine arm.
[0004] US4961543 discloses a rotation adjusting apparatus in a crusher that adjusts the wear during
use of a rotational mechanism. The crusher may have a rotational housing with a pair
of pawls which crushes or cuts an object, such as a reinforced concrete or a steel
frame. The object to be crushed or cut may be held to a fixing member by a holding
member such that a wear is adjustable, and the housing can be rotated to a desired
rotational angle and fixed by rotation restricters and a rotation stopper.
[0005] US200517528 discloses a device for mounting a rotating implement to a crane arm or similar. The
device comprises a rotator located between the crane arm and the unit that at one
end is pivot-mounted to the implement for rotating the same relative to the crane
arm and at the other end is mounted to the crane arm via a hinged link.
[0006] DE202010007136 discloses a rotatable bucket that is movable relative to an arm through a horizontal
motor and a rotary motor. The motors connect the bucket to an adapter.
[0007] US5664734 discloses a crusher having a frame that is rotatable relative to an arm. The frame
is rotatable relative to the arm through a relative movement between a bearing ring
and a ring gear. A motor for providing the rotation of the frame is located in a bracket.
[0008] The present disclosure is directed, at least in part, to improving or overcoming
one or more aspects of the prior art system.
Brief Summary of the Invention
[0009] The present disclosure describes a demolition tool comprising a frame. The frame
comprises: a housing having a machine end and a jaw end; a bearing assembly positioned
