An modular lift system for hoisting objects along a track to a predetermined height. The lift system may include a limit switch, a carriage with an automatic emergency braking system, and a peak to engage the track, whereby the carriage rolls along the side rails of the track between the peak mounted to the top of the track and the bottom of the track. The carriage can be adjustable thereby permitting it to be adapted to various types and sizes of tracks. The automatic emergency braking system is adapted to prevent the uncontrolled descent of the carriage in the event of a cable or primary brake failure.

The apparatus for moving a load includes a carrier cable having a first end connected to the load, and a second end connected to a movement device, the movement device including an operating line connected to a movement carriage. An electric motor is configured to move the carriage as a function of a force exerted on the operating line.

A free-fall safety device for installation on a machine assembly having a load includes a base member having a locking member disposed thereon, a lifting member releasably secured to the base member, the lifting member for supporting the load in position on the machine assembly, wherein the base member is rotatable in response to a reduction in tension applied to the lifting member, in order to engage the locking member to lock the base member and lifting member in position on the machine assembly. In one embodiment, rotation of the base member is effected by decompression of a moveable member in response to a change in tension within the lifting member. If the lifting member suffers a sudden catastrophic failure, then tension in the lifting member will be released, which in turn will activate and decompress the moveable member and cause the base member to rotate into a locking position.

A suspension lift apparatus includes a platform, a plurality of direction changing sheaves and lifting sheaves mounted to the platform, a plurality of cables and a lifting mechanism positioned on the platform. Ends of cables mounted above the platform extend through the sheaves and are coupled at the opposite cable ends to the lifting mechanism disposed on the platform. Actuation of the lifting mechanism causes the platform to rise or descend. The cables are anchorable to a structure such as a ceiling above the platform. The suspension lift apparatus may include legs to provide an overhead anchor point.

A lifter includes a support base, a first elevating stand assembly, a first elevating-drive mechanism, a turning-drive mechanism and a bracket mechanism. A lower portion of the first elevating stand assembly is provided with two sets of first fixing racks. The support base is symmetrically mounted on the first fixing racks. One side of the first elevating stand assembly is provided with a first elevating-drive mechanism. A first elevating stand is installed inside the first elevating stand assembly. The first elevating-drive mechanism drives the first elevating stand to move through the transmission mechanism. The turning-drive mechanism is provided with a support base. One end of the support base is hinged to a movable support frame. The other end of the support base is provided with a locking assembly. The turning-drive mechanism is provided with a bracket mechanism.

A portable dry chemical delivery robot comprised of a cart, a hoist mounted to the top brace; a moveable hopper with a flared inlet tapering to an outlet and connected to the hoist and contained within the cart, a screw conveyor connected to the outlet of the moveable hopper, a motor with transmission connected to the screw conveyor with a remote power supply, a flow controller connected to the motor for regulating operation of the screw conveyor, the flow controller being in communication with a network for providing both local and remote control of the screw conveyor from at least one client device connected to the network.
