A Boom Assembly For An Earthmover

Abstract: The present disclosure discloses a boom assembly (100) for an earthmover (200). The boom assembly (100) comprises a boom, a first actuator (2), a connecting member (31) and a second actuator (32). The boom is coupled to a portion of a chassis (21) and is defined with a first portion (11) and a second portion (12). The boom is pivotable between an actuated state, an intermediate state and a lowered state relative to a cabin (40) of the earthmover (200). The second actuator (32) is connectable between the chassis (21) and the connecting member (31) and is configured to pivot the boom between the intermediate state and the lowered state. With such configuration, visibility of an operator in a cabin (40) of the earthmover (200) is enhanced and obstruction by the boom of the boom assembly (100) may be reduced or eliminated. Figure 1a is a representative figure.

Specification

Description:PLEASE REFER THE ATTACHMENT , Claims:PLEASE REFER THE ATTACHMENT

WE CLAIM:
1. A boom assembly (100) for an earthmover (200), the boom assembly (100) comprising:
a boom (1) coupled to a portion of a chassis (21), wherein the boom (1) is defined
with a first portion (11) and a second portion (12), and is pivotable between an actuated
state, an intermediate state and a lowered state relative to a cabin (40) of the earthmover
(200);
a first actuator (2) connected between the first portion (11) of the boom (1) and
the chassis (21), wherein the first actuator (2) is configured to pivot the boom (1)
relative to the chassis (21) between the actuated state and the intermediate state;
a connecting member (31), adapted to connect to the second portion (12) of the
boom (1) and the chassis (21), wherein the connecting member (31) is configured to
pivot the boom (1) relative to the chassis (21);
a second actuator (32), connectable between the chassis (21) and the connecting
member (31), wherein the second actuator (32) is configured to pivot the boom (1)
between the intermediate state and the lowered state, and
wherein the second actuator (32) is configured to pivot the boom (1) about
the second portion (12) to pivot the boom (1) relative to the cabin (40) between
the intermediate state and the lowered state.

2. The boom assembly (100) as claimed in claim 1, wherein the second portion (12) is
defined proximal to an end of the boom (1), the end of the boom (1) being connected
to the chassis (21) and the first portion (11) is defined away from the second portion
(12).
3. The boom assembly (100) as claimed in claim 1, wherein the connecting member (31)
defines at least one arcuate surface (31a) along a longitudinal direction to pivotably
accommodate a portion of the boom (1) relative to the second portion (12).
4. The boom assembly (100) as claimed in claim 1, wherein the first actuator (2) is adapted
to pivot the boom (1) away from the cabin (40) to the actuated state.
5. The boom assembly (100) as claimed in claim 1, wherein the first actuator (2) is adapted
to pivot the boom (1) towards the cabin (40) in the intermediate state, wherein the boom
(1) comprises at least one edge (1a).

6. The boom assembly (100) as claimed in claim 5, wherein the at least one edge (1a) of
the boom (1) is inclined with a lateral axis (AA’) of the cabin (40) in the intermediate
state.
7. The boom assembly (100) as claimed in claim 6, wherein the second actuator (32) is
adapted to pivot the boom (1) towards the cabin (40), wherein the at least one edge (1a)
of the boom (1) is inclined at a predetermined angle relative to the lateral axis (AA’) of
the cabin (40) in the lowered state.
8. The boom assembly (100) as claimed in claim 1, wherein the second actuator (32) is
connectable on one end to one of the connecting member (31) and the second portion
(12) of the boom (1) and is connectable to the chassis (21) on an other end opposite to
the one end.
9. The boom assembly (100) as claimed in claim 8, wherein the boom assembly (100)
comprises a plurality of pins (50) disposed at the first portion (11), the second portion
(12), and the chassis (21).
10. The boom assembly (100) as claimed in claim 9, wherein the plurality of pins (50)
operatively connects the first actuator (2), the second actuator (32) and the connecting
member (31) to the boom (1) and the chassis (21).
