    摘要： An electric hoist with a brake motor having an output shaft oriented in the horizontal direction; a shaft located immediately below the output shaft of the brake motor and pivoting parallel to the output shaft; a chain sprocket affixed on the shaft and having a load chain wound thereon; gears provided on the output shaft side of the brake motor, the gears meshing with each other between the output shaft and one end of the shaft and transmitting the output of the brake motor to the shaft; and an upper hook provided above the brake motor and horizontally suspending the shaft with no load suspended, the shaft connected to the brake motor through the gears. The chain sprocket is provided on the shaft such that the portion of the chain sprocket on which the load chain is wound is located on the vertical line which passes through the upper hook.

    摘要： A hoist limiting system (15) comprising a frame (16), a hoist drum (17) supported by the frame and rotatable about a hoist axis (x-x), a hoist driver (19) supported by the frame and configured to rotate the hoist drum in opposite upward (30) and downward (31) directions about the hoist axis, a hoist line (18) in engagement with the hoist drum such that the hoist line winds in the upward or downward direction in response to rotation of the hoist drum, at least one gear (20) mechanically coupling the hoist driver and hoist drum and configured to rotate about a gear axis (x-x), the gear having a face (21) that rotates about the gear axis in a upward or downward direction in response to rotation of the hoist drum, a first proximity limit switch (26) supported by the frame adjacent the rotating face such that the rotating face moves relative to the proximity switch and a second proximity limit switch (28) supported by the frame adjacent the rotating face such that the rotating face moves relative to the second proximity switch, the first and second proximity switches configured to sense the presence or absence of the face and communicating with a controller (29), the first and second proximity switches, the control unit, and the hoist driver configured to prevent the hoist drum from rotating in the upward direction as a function of signals from the first and the second proximity switches and configured and arranged to prevent the hoist drum from rotating in the downward direction as a function of the signals from the first and the second proximity switches.
