In an elevator hoisting machine mounting device, an elastic support device includes a supporting elastic body that deforms elastically upon reception of a load from a hoisting machine unit. A buckling suppression device disposed at a remove from the elastic support device in a horizontal direction includes first and second buckling suppression elastic bodies that sandwich, from above and below, a buckling suppression attachment portion provided on a lower portion of the hoisting machine unit, and a holding tool that holds the first and second buckling suppression elastic bodies on a machine base. The buckling suppression device suppresses, by an elastic restoring force of the first and second buckling suppression elastic bodies, buckling of the hoisting machine unit relative to the machine base due to the elastic deformation of the supporting elastic body.

An elevator system includes a lifting platform for securing at a plurality of securing positions in an elevator shaft and at least one guide rail for vertically guiding an elevator car in the elevator shaft. The lifting platform has a protective roof that protects the lifting platform against falling objects, wherein the protective roof has a rail opening, through which the guide rail extends, and wherein the protective roof has a cover covering the rail opening, the cover having a cover opening through which the guide rail extends.

A lifting system for post frame construction comprises a winch system coupled to a frame, a first bracket configured to be secured to a portion of a roof framing system, and a pulley system comprising at least two pulley wheels mounted on a second bracket. The frame is configured to be secured to a lower portion of a column of a building structure and the second bracket is configured to be secured to a top of the column.

An elevator system includes a hoistway and an elevator car positioned in and movable along the hoistway. The elevator car includes a first sheave and a second sheave spaced apart from the first sheave. The first sheave and second sheave have parallel axes of rotation and each include a traction surface and a gearless prime mover operably connected to the traction surface to drive rotation of the traction surface. A first load bearing member is positioned in the hoistway and a second load bearing member is positioned in the hoistway. The first load bearing member passes laterally under the first sheave, vertically upward between the first sheave and the second sheave, and laterally over the second sheave. The second load bearing member passes laterally under the second sheave, vertically between the second sheave and the first sheave, and laterally over the first sheave.

An elevator drive unit includes a drive shaft having at least one drive section for driving a drive belt. The drive unit also includes an electromotor, for driving the drive shaft having a stator and a rotor, a brake for braking the drive shaft, and a frame for supporting the drive shaft, the stator and the brake.

An elevator system includes a hoistway and an elevator car suspended in the hoistway via one or more suspension members. A counterweight is suspended in the hoistway via the one or more suspension members to balance operation of the elevator car. A machine is positioned at the hoistway to drive the one or more suspension members along the hoistway, driving motion of the elevator car and/or counterweight along the hoistway. A suspension member termination is supported at the machine, to secure an end of the one or more suspension members. A drive system for an elevator includes one or more elevator suspension members and a machine interactive with the one or more elevator suspension members to drive motion of an elevator car. A suspension member termination is supported at the machine to secure an end of the one or more suspension members at the machine.
