Lifting assembly for dust curtain of work machine

A work machine comprising:

• a frame;
• a curtain assembly coupled to the frame and adapted to enclose a work area, the curtain assembly including a dust curtain disposed proximal to a first end of the work machine, wherein the work machine is a drilling or mining machine;
• and
• a lifting assembly for the dust curtain, the lifting assembly including:
• a pair of mounting brackets, each mounting bracket defining a first end and a second end distal from the first end, each mounting bracket being coupled to the frame of the work machine at the first end;
• an arm assembly pivotally coupled to each mounting bracket at the second end of a corresponding mounting bracket, the arm assembly being movable relative to the mounting brackets between a first state in which the dust curtain is disposed in a lowered position and a second state in which the dust curtain is disposed in a lifted position, the arm assembly defining a third end and a fourth end distal from the third end, the arm assembly including:
• a first arm member coupled to one of the pair of mounting brackets, the first arm member including a first linear portion and a first curved portion extending from the first linear portion;
• and
• a second arm member coupled to another of the pair of mounting brackets, the second arm member including a second linear portion and a second curved portion extending from the second linear portion;
• a lifting plate coupled to the dust curtain;
• and
• a linkage assembly coupling the arm assembly with the lifting plate, wherein the linkage assembly is coupled to the arm assembly at the fourth end of the arm assembly.
