Jump elevator and jumping method

A jump elevator comprising:

• a machine room provided in a hoistway and configured to be fixed or movable relative to the hoistway;
• at least one lifting assembly comprising:
• a frame attached to the outside of the hoistway and partially extending into the hoistway;
• a pulley assembly including a winch, a fixed end of the frame, and a plurality of pulleys disposed on the machine room and the frame;
• wherein a pulling line is disposed between the winch, the plurality of pulleys, and the fixed end;
• wherein the frame includes a first arm and a second arm;
• wherein a first end of the first arm and a first end of the second arm extending into the hoistway and respectively mounting a first pulley and a second pulley;
• and wherein a second end of the first arm and a second end of the second arm extend and are fixed to the outside of the hoistway;
• wherein the winch is disposed at a second end of the first arm and the fixed end is disposed at a second end of the second arm.

• wherein the frame further comprises a connecting arm, wherein the first arm and the second arm are attached to the connecting arm;
• wherein the connecting arm, the first arm and/or the second arm are removably fixed in place out of the hoistway by one or more spacer arms.

A method of jumping, comprising:

• 1) installing at least one detachable lifting assembly outside a hoistway above a machine room, wherein the lifting assembly is disposed below a covering portion of the hoistway and configured to suspend the machine room, a frame attached to the outside of the hoistway and partially extending into the hoistway, the frame having at least one arm extending through a wall of the hoistway;
• 2) separating the machine room from an inner wall of the hoistway;
• 3) activate the at least one detachable lifting assembly to move the machine room to a target location;
• 4) positioning the machine room in relative to the inner wall of the hoistway at the target location.
