second hinges 500 510 in the illustrated configuration the hinge pins 520 530 are rotatable within the hinges 500 510 to allow the door assembly 200 to rotate with respect to the loader 10 the door assembly 200 further includes a latching mechanism 550 on the opposite side of the door assembly 200 as the hinges 500 510 and hinge pins 520 530 when an operator desires to enter or exit the loader 10 the latching mechanism 550 can be actuated to allow the door assembly 200 to pivot at the hinges 500 510 about hinge pins 520 530 in some circumstances the door assembly 200 cannot pivot about the hinges 500 510 and hinge pins 520 530 due to lack of space an object in the way of the door path or various other reasons also in some emergency cases it may be desirable to detach the door assembly 200 from the loader 10 to allow for quick egress from the operator compartment 35 a lever 560 is provided on the interior of the operator compartment 35 for rotation relative to the door frame 210 the lever 560 is coupled to a cam member 570 for rotation with the cam member 570 the hinge pins 520 530 are coupled to the cam member 570 for substantially linear movement into and out of the hinges 500 510 in response to rotation of the lever 560 and cam member 570 the illustrated hinge pins 520 530 and the cam member 570 are positioned on the exterior of the loader 10 rotation of the lever 560 causes the door assembly 200 to detach from the loader 10 and thereby allow.
