A storage system includes a framework structure, at least one container lift device, and a plurality of storage containers. The framework structure includes multiple storage columns, in which the storage containers are stored on top of one another in vertical stacks. The container lift device includes a lifting frame for releasable connection to one of the storage containers when the lifting frame is lowered into one of the storage columns to retrieve said storage container. An outer periphery of each storage container includes a vertical guiding pin recess at each of four container corners. A vertical guiding pin is provided at each of four frame corners of the lifting frame. A lower part of at least two of the guiding pins have a container support portion including a container support surface.

A movement device is moved along an X axis and a Y axis by providing a sensor configured to measure angle of rotation of at least one of a first and a second kinematic link about a respective axis of rotation. A force is imparted on the first and second kinematic links such that an angular displacement of the first and second kinematic links about the respective axis of rotation is achieved. The angular displacement of the first and second kinematic links about the respective axis of rotation is determined. The movement device is moved along the X axis and/or the Y axis in response to the determination of the angle of rotation of the first and second kinematic links about the respective axis of rotation until first and second kinematic links are vertical.

A support for a trolley, having a running surface that is formed on the support for the trolley, an upper chord, a lower chord and braces that connect said chords together, wherein the braces are designed to be flat, and each brace has a main surface that faces away from the support longitudinally between the upper chord and the lower chord. Two of the braces form a brace pair in each case and are arranged next to one another as viewed in the direction of the longitudinal axis of the support, preferably on the outside of opposite longitudinal sides of the support. To provide such a support, the flat braces are releasably secured to the upper chord and/or to the lower chord. The invention also relates to an overhead transport device having such a support and a trolley that can be moved along the support on the running surface.

A suspension type lifting device includes a base unit, a bearing unit, a balance unit, a servo unit and a hanging unit. The base unit includes a first plate, a second plate and a third plate. The bearing unit includes a positioning piece and two forks. The balance unit is connected with the third plate of the base unit. The servo unit is connected with the first plate of the base unit. The hanging unit is mounted on the first plate of the base unit. When the servo unit detects that a foreign object is placed on the bearing unit, the servo unit calculates a value required for reaching a balance weight and transmits a power to drive the balance unit to swing leftward and rightward, so as to reach a balance state.

A transfer system for spent fuel canisters includes a carrier, a shielded bell trolley movable along the carrier and carrying a shielded bell, and a canister trolley movable along the carrier and carrying a lifting mechanism for raising and lowering the spent fuel canister into and out of the shielded bell. The canister trolley can move along the carrier independent of the shielded bell trolley and the shielded bell trolley can move along the carrier independent of the canister trolley. The shielded bell trolley and the canister trolley can be selectively interlocked for selected transfer operations.
