A support assembly including a coupler, a first arm having a proximate end movably coupled to the coupler, a distal end opposite the proximate end, and a second arm having a proximate end movably coupled to the coupler, a distal end opposite the proximate end. The support assembly is movable between a disengaged position and an engaged position. When moving from the disengaged position to the engaged position, the distal end of the first arm and the distal end of the second arm move toward each other.

In a manual/automatic non-electric-connection borehole clinometer for a landslide, a clinometer probe completes borehole inclination measurement; a hoisting mechanism is connected to the clinometer probe by a pull rope; and a first tooth disc of an automatic clutch and a first tooth disc of a manual clutch are fixed to a left shaft end and a right shaft end of the hoisting mechanism respectively, a second tooth disc of the automatic clutch is fixed to a driving shaft of an electric driving mechanism and selectively meshes with or moves away from the first tooth disc of the automatic clutch, and a second tooth disc of the manual clutch is fixed to a driving shaft of a manual driving mechanism and selectively meshes with or moves away from the first tooth disc of the manual clutch.

The present application is directed to a tree stand lift system for elevating a person into a tree or other structure. The tree stand lift system includes, in an embodiment, a hunting platform assembly for supporting a person; a hoist assembly positioned above the platform; a hoist cable secured to the hoist assembly and positioned to lift a person from the ground up to the platform.

A winding machine wherein a motor control means is able to control driving of a drive motor in a balancer mode, and the balancer mode includes a first balancer mode in which driving of the drive motor is controlled based on a first torque command value with an assist torque that assists the operating force added thereto, and a second balancer mode in which driving of the drive motor is controlled based on a second torque command value that does not assist the operating force, and a lifting/lowering position range is set to a first position range where control is performed in the first balancer mode regardless of the direction of the operating force being in either the winding up or winding down direction, and a second position range where control is performed to select whether control is performed in the first balancer mode or in the second balancer mode.

A hoist comprising: an upper hook; a support shaft that includes a hook-side large-diameter portion inserted through an insertion hole of the hook at a center portion, end large-diameter portions at both ends, an intermediate portion between the hook-side large-diameter portion and the end large-diameter portion, and a strain deformation portion that is provided at the intermediate portion; a main frame that includes a pair of support holes and is suspended and supported by the upper hook via the support shaft with the end large-diameter portion on one side inserted in the one support hole and the end large-diameter portion on the other side inserted in the other support hole; and a load measurement means that is attached to the strain deformation portion and measures a shear load acting on the strain deformation portion, wherein at least a portion of the intermediate portion is inserted in the support hole.

A system has a hoist system to lift a payload to a position adjacent to a ceiling of a room Image sensor systems collect visual data and payload depth data within the payload and ambient depth data within the room. A controller is connected to the hoist system and the image sensor systems. The controller is configured to control the motion of the hoist system. The motion of the hoist system is controlled in part by the ambient depth data from the room.

A rack system which includes a rack frame and at least one reservoir for housing at least one rack-mounted immersion case is disclosed. The rack frame is configured to slidably accommodate racking and de-racking operations of the at least one rack-mounted immersion case. The at least one collapsible reservoir, which is configured to store a fluid therein, is fluidly connected to the at least one rack-mounted immersion case, has a first portion fixedly connected to the at least one rack-mounted immersion case, and a second portion fixedly connected to the rack frame. The at least one collapsible reservoir is configured to respectively collapse and expand along a racked space and a de-racked space, the racked and de-racked spaces being defined between a backplane of the at least one rack-mounted immersion case and a backplane of the rack frame, the de-racked space being larger than the racked space.

A system for servicing a pulverizer includes a pulverizer having a housing, a journal assembly pivotally connected to the housing, a grinding mechanism operatively connected to the journal assembly, and an opening within the housing adjacent to the journal assembly and providing an access point to an interior of the housing, and a hoist apparatus mounted to the housing. The hoist apparatus includes a frame assembly received about the opening in the housing, a sheave assembly including a plurality of sheaves supported by the frame assembly, a motor operatively connected to one of the plurality of sheaves, and a cable received by the sheave assembly. The motor is operable to at least one of retract the cable through the sheave assembly to rotate a component out of the pulverizer through the opening and controllably let out the cable to rotate the component into the pulverizer through the opening.

A lifting apparatus for a highly-mounted device includes a main body installed at a predetermined height so that a drum for winding a wire rope and a first driving motor for giving a rotating force to the drum are installed thereto; a lifting body suspended from the wire rope and having a device coupling portion provided at a lower end thereof; an accommodation structure located at a lower portion of the main body and having an open lower portion so as to be coupled with the lifting body; a stopper installed at the accommodation structure and caught by a suspending protrusion provided to the lifting body to give an anti-falling function for the lifting body; and an upper contact point and a lower contact point respectively installed at the main body and the lifting body to make contact with each other when the lifting body is moved up.
