Elevator with an operation space in a center of a machine room

An elevator system comprising:

• an elevator shaft in which a cage and a counterweight that are suspended by a hoist rope as a jig back are vertically moved;
• a machine room that has a floor area equivalent to a cross-sectional area of the elevator shaft, and is arranged above the elevator shaft;
• an elevator hoist that is arranged along a first inner wall surface of inner wall surfaces of the machine room, the first inner wall surface extending above one of right and left sidewalls of the cage in a front and back direction;
• a rope hitching portion for hitching at least one of ends of the hoist rope, and arranged near a second inner wall surface of the inner wall surfaces of the machine room, the second inner wall surface extending above the other of the right and left sidewalls of the cage in the front and back direction;
• and
• a control panel that is arranged along a third inner wall surface or the second inner wall surface of the inner wall surfaces of the machine room, the third inner wall surface extending adjacent to the first inner wall surface in a right and left direction, perpendicular to the front and back direction,
• wherein each of the elevator hoist, the rope hitching portion, and the control panel is arranged around and outside of a unified operation space in a center part of the machine room, wherein said unified operation space is a space free of all equipment.

An elevator system comprising:

• a machine room that has a floor area equivalent to a cross-sectional area of an elevator shaft, and is arranged above the elevator shaft;
• a cage that is guided by a pair of right and left cage-side guide rails to vertically move in the elevator shaft;
• a counterweight that is guided by a pair of counterweight-side guide rails to vertically move in the elevator shaft on one side of right and left sidewalls of the cage;
• a traction sheave that is rotated about a rotational axis extending in a front and back direction, and is arranged along a first inner wall surface of inner wall surfaces of the machine room, the first inner wall surface extending above the counterweight in the front and back direction;
• a driving apparatus for driving the traction sheave in rotation, and arranged along the first inner wall surface in the machine room such that an axis of the driving apparatus extends in the front and back direction;
• a cage-side sheave disposed on the cage;
• a hoist rope that is passed round the traction sheave, and has one end extending down apart from an inner wall surface of the elevator shaft to suspend the cage via the cage-side sheave and another end extending down along the inner wall surface of the elevator shaft suspending the counterweight;
• a cage-side rope hitching portion for hitching the one end of the hoist rope suspending the cage, and is arranged near a second inner wall surface of the inner wall surfaces of the machine room, the second inner wall surface extend opposite to the first inner wall surface in the front and back direction;
• and
• a control panel for controlling the driving apparatus, and arranged along a third inner wall surface adjacent to the first inner wall surface of the inner wall surfaces of the machine room, or the second inner wall surface,
• wherein each of the traction sheave, the cage-side rope hitching portion, and the control panel is arranged around and outside of a unified operation space in a center part of the machine room, wherein said unified operation space a space is free of all equipment.

• a cage that is guided by a pair of right and left cage-side guide rails to vertically move in the elevator shaft;
• a counterweight that is guided by a pair of counterweight-side guide rails on a side of a rear wall of the cage to vertically move in the elevator shaft;
• a traction sheave that is rotated about a rotational axis extending in a front and back direction, and is arranged along a first inner wall surface of inner wall surfaces of the machine room, the first inner wall surface extending above one of right and left sidewalls of the cage in the front and back direction;
• a driving apparatus for driving the traction sheave in rotation, that is arranged along the first inner wall surface in the machine room such that an axis of the driving apparatus extends in the front and back direction;
• a cage-side sheave disposed on the cage;
• a deflecting sheave arranged along an inner wall surface of the elevator shaft;
• a hoist rope that is passed round the traction sheave, and has one end extending down apart from an inner wall surface of the elevator shaft to suspend the cage via the cage-side sheave and another end extending down along the inner wall surface of the elevator shaft extending to the counterweight by being guided by the deflecting sheave to suspend the counterweight;
• a cage-side rope hitching portion for hitching the one end of the hoist rope suspending the cage, and arranged near a second inner wall surface of the inner wall surfaces of the machine room, the second inner wall surface extend opposite to the first inner wall surface in the front and back direction;
• and
• a control panel for controlling the driving apparatus, and arranged along a third inner wall surface adjacent to the first inner wall surface of the inner wall surfaces of the machine room, or the second inner wall surface,
