Control cab support mechanism

An apparatus comprising:

• (A) a mineral processing machine having a portable chassis;
• and
• (B) a control cab assembly for housing an operator, said control cab assembly including
• (1) a control cab;
• and
• (2) a control cab support mechanism on which said control cab is mounted, said control cab support mechanism being actuatable to raise said control cab from a first position in which said control cab is supported on said chassis to a second position in which said control cab is lifted from said chassis and supported on the ground, wherein said control cab support mechanism includes
• a. an upper platform on which is mounted said control cab;
• b. a lower platform for engaging the ground;
• c. a support platform which is positioned between said upper and lower platforms and which rests on said chassis when said control cab is in said first position;
• d. an upper scissor mechanism connecting said upper platform to said support platform;
• and
• e. a lower scissor mechanism connecting said lower platform to said support platform.

A mineral processing machine comprising:

• (A) a portable chassis;
• (B) a mineral processing device mounted on said chassis;
• (C) a control cab;
• and
• (D) means for moving said control cab vertically and linearly from an in pit transport position in which said control cab is supported only on said chassis to an operative position in which said control cab is (1) lifted from said chassis and (2) supported only on the ground.

An apparatus comprising:

• (A) a portable chassis;
• (B) a mineral processing device mounted on said chassis;
• (C) a control cab;
• (D) means for lifting said control cab from an in pit transport position in which said control cab is supported on said chassis to an operative position in which said control cab is (1) lifted from said chassis and (2) supported on the ground;
• and
• (E) a pair of support arms attached to and extending transversely away from said chassis and forming a support assembly for said control cab when said control cab is in said in pit transport position.

An apparatus comprising:

• (A) a mineral processing machine having a portable chassis;
• and
• (B) a control cab assembly for housing an operator for said mineral processing machine, said control cab assembly including
• (1) a control cab;
• and
• (2) a control cab support mechanism on which said control cab is mounted, said control cab support mechanism being actuatable to move said control cab vertically from a first position in which said control cab is supported on said chassis to a second position in which said control cab is lifted from said chassis and supported on the ground at a location beneath said chassis, wherein said control cab is at a first designated height when in said first position and at a second designated height when in said second position, said second designated height being higher than said first designated height.

An apparatus comprising:

• (A) a portable chassis;
• (B) a mineral processing device mounted on said chassis;
• (C) a support assembly mounted on said chassis;
• (D) a control cab;
• and
• (E) a scissor lift mechanism on which said control cab is mounted, said scissor lift mechanism being movable from a first position in which said control cab is supported on said support assembly to a second position in which said control cab is lifted to a designated height above said support assembly and supported on the ground, said scissor lift mechanism including
• (1) an upper platform on which is mounted said control cab;
• (2) a lower platform for engaging the ground;
• (3) a support platform which is positioned between said upper and lower platforms and which rests on said support assembly when said scissor lift mechanism is in said first position;
• (4) an upper scissor mechanism connecting said upper platform to said support platform;
• and
• (5) a lower scissor mechanism connecting said lower platform to said support platform.
