A an energy storage system includes a crane and a plurality of blocks, where the crane is operable to move blocks from a lower elevation to a higher elevation (via stacking of the blocks) to store electrical energy as potential energy of the blocks, and then operable to move blocks from a higher elevation to a lower elevation (via unstacking of the blocks) to generate electricity based on the kinetic energy of the block when lowered (e.g., by gravity). The energy storage system can, for example, store electricity generated from solar power as potential energy in the stacked blocks during daytime hours when solar power is available, and can convert the potential energy in the stacked blocks into electricity during nighttime hours when solar energy is not available, and deliver the converted electricity to the power grid.

A suspended tire manipulator for use by an operator in lifting a tire having a mounting aperture includes a first handle attached to a first proximal arm. The first proximal arm is connected to a first distal arm at an obtuse angle. The manipulator includes a rotary balancer pivotally mounted to the first distal arm. The rotary balancer provides a pivoting torque to the first distal arm in response to operator movements raising and lowering the manipulator via manual force applied at the handle. A vertical support has a lower end and an upper end. The lower end connects to the rotary balancer. The manipulator includes a pair of gripper shoes. The pair of gripper shoes are slidably mounted on a rail and move in opposite inboard and outboard directions on the rail.

A conveying device of the present invention includes a holding unit configured to hold a conveying object, a support member swingably supporting the holding unit, a plurality of hanging members, each distal end of which is connected to the support member so as to hang the holding unit via the support member, reel units to which each proximal end of the plurality of hanging members is connected so as to be capable of feeding and wounding, a base part on which the plurality of reel units are mounted, a guide unit configured to engage with the holding unit, and guide the holding unit to be elevated, and a control unit configured to perform operation control on the reel units so as to feed and wind the hanging member.

There is provided a device for handling tires having an anchor for attaching to a prime mover and a clamping device rotatably mounted to the anchor that rotates relative to the anchor about a rotation axis. The clamping device has a plurality of engagement members connected by a mechanical linkage and a carrying body with a plurality of guides. The weight distribution of the clamping device is balanced about the rotation axis. Each guide carries one of the engagement members and is oriented to allow the engagement members to move perpendicular to the rotation axis between clamping and release positions. The mechanical linkage includes a rotating actuator and controls movement of the engagement members along the guides. The movement of each engagement member is rotationally symmetric about the rotation axis relative to the movement of the other engagement members. The device has an actuator that actuates the mechanical linkage.

A rope, a system and a method for measuring one or more properties of a rope. A property evaluation system for ropes can be deployed for a number of different applications including, but not limited to, moving lines, e.g., crane or winch and static lines, e.g., mooring lines, stays, etc., to evaluate physical properties of the ropes and, in some cases, to help evaluate structural health of the ropes. A sheave assembly (10) may transmit a signal into a rope (14) to measure at least one property of the rope. At least one sensor (25) may be coupled to or assembled in the rope to measure at least one property of the rope.
