| In an elevator, preferably one without machine room, a hoisting machine engages a set of hoisting ropes via a traction sheave, said set of hoisting ropes having a load-bearing part twisted from steel wires of circular and/or non-circular cross-section, and in which elevator the hoisting ropes support a counterweight and an elevator car moving on their tracks. The weight of the hoisting machine of the elevator is at most about null of the weight of the nominal load of the elevator. | ||||||
| 142 | Connector for connectible belt and method for using same | US529946 | 1990-05-29 | US5011462A | 1991-04-30 | Thomas R. Smith |
| The belt connector of the present invention comprises an elongated shank having two J-hooks at its opposite ends. Each J-hook is performed to make an elongated slot which is approximately one half the width of the diameter of the loop member which forms the loops at the ends of the connectible belt. When the loops are forced into the slots of the J-hooks of the connector, they are compressed to form an oval shape which resists movement or turning within the slot. | ||||||
