An example electric motor includes a housing, a stator fixed relative to the housing, a rotor, a brake assembly, a first bearing, and a second bearing. The rotor has a hub portion, a cylindrical portion, and a disk portion. The hub portion of the rotor has a first end, a second end, and a through hole therethrough. The brake assembly is fixed relative to the housing and configured to selectively couple the disk portion of the rotor to the housing. The first bearing is mounted between the first end of the hub portion of the rotor and the disk portion of the rotor. The second bearing is mounted between the second end of the hub portion of the rotor and the disk portion of the rotor.

A rope grab for a vertical fall protection system is provided. The rope grab includes a housing with an elongated member passage. The elongated member passage is configured to receive an elongated member. A locking cam is pivotally coupled to the housing and selectively engages an elongated member received in the elongated member passage. A cam spring is coupled between the housing and the locking cam to provide a relatively slight biasing force on the locking cam in a direction towards an elongated member received in the elongated member passage. A locking arm, pivotally coupled to the housing, has a first end that is configured to be coupled to a safety harness of a user and a second end that selectively engages the locking cam to lock the locking cam on an elongated member in the elongated member passage during a fall event.

A cable connector assembly comprises a first stop, a second stop, and a connector. The first stop is configured and arranged to receive a first end of a cable, and the second stop is configured and arranged to receive a second end of the cable. The connector is configured and arranged to pivotally interconnect the first stop and the second stop.

An energy absorber comprises an intermediate portion interconnecting a first end and a second end. The intermediate portion and the first and second ends are on the same plane. The intermediate portion includes curved portions configured and arranged to deform and begin to straighten when subjected to a pre-determined load to absorb energy from the pre-determined load. Should a user fall, the energy absorber will deform (begin to straighten) to absorb energy from the fall. Optional pins prevent material from getting caught in the energy absorber, assist in stiffening the energy absorber, and assist in pre-stressing the energy absorber so that it will not open up when subjected to a load less than the pre-determined load. Optional tabs and slots or protrusions and notches prevent material from getting caught in the energy absorber.

A fall protection safety device including a braking mechanism comprises a first component, a second component configured and arranged to move relative to the first component, and at least one magnet operatively connected to one of the components and another of the components being at least partially made of a non-ferromagnetic and electrically conductive material. The at least one magnet and the non-ferromagnetic and electrically conductive material creating an electromagnetic field force when the second component moves at a rate greater than a predetermined rate relative to the first component.

Jet bridge shuttle

A fall protection system that includes at least one rail section, at least one shuttle and at least one connecting member is provided. The at least one rail section is configured and arranged to be coupled to a structure that changes in length. The at least one shuttle is configured and arranged to movably engage the at least one rail section. In addition, the at least one connecting member is configured and arranged to provide a connection point to the at least one shuttle.
