Disclosed herein is a motorized motorcycle stand. The motorized stand includes a lifting platform. The motorized stand further includes an electric motor. The motorized stand further includes a lift column. The motorized stand further includes at least one stabilizing column. The motorized stand further includes a motor housing. The electric motor is oriented at an acute angle with respect to a plane defined by said lift column and stabilizing column.

A rotating shaft lifting jig is inserted between a rotating shaft of a rotary machine and a bearing stand surrounding the outer periphery of at least a lower part of the rotating shaft. The jig for lifting the rotating shaft includes: a pedestal which is supported on an inner peripheral surface of the bearing stand; and a jack part which is disposed between the pedestal and the outer peripheral surface of the rotating shaft and extends/contracts in the radial direction. The radial dimension of the pedestal is smaller than a radial clearance between the rotating shaft and the bearing stand. A rotor receiver having a cylindrical surface conforming to the outer peripheral surface of the rotating shaft is provided between the jack part and the rotating shaft. The rotor receiver is provided with a plurality of support members in directions different from the direction of the jack part.

Apparatus and methods for lifting loads are described. The load lift includes a support frame and a lift assembly with main cylinder and at least one standby cylinder connecting a rotatable cross beam with a clamp plate. A rotary actuator assembly is connected to the lift beam to move the lift assembly out of the way while not in use by rotating the lift assembly from a lift position to a standby position.

An article conveying equipment includes: a carrying apparatus, configured to carry one or more articles to be transported; a travelling apparatus, where the travelling apparatus includes at least two driving wheels located at the bottom of the travelling apparatus, the at least two driving wheels are configured to control the travelling apparatus to rotate in a first rotation direction; and a rotation supporting apparatus, which is located between the carrying apparatus and the travelling apparatus and connected to the carrying apparatus and the travelling apparatus respectively, where the rotation supporting apparatus is configured to rotate in a direction opposite to the first rotation direction when the travelling apparatus rotates in the first rotation direction.

A jack for lifting segments of a structure includes a pair of masts, a mast base, a mast cap, a hydraulic ram, a bottom bracket and a shuttle. The masts are identical and upright with a plurality of evenly spaced holes. The mast base supports the mast and the mast cap receives the upper ends of the masts and maintains the masts in a parallel, relationship. The hydraulic ram moves between a retracted position and an extended position with a stroke distance which is significantly less than the mast height. The bottom bracket is removably pinned to the masts and receives and supports the lower end of the hydraulic ram. The shuttle receives the upper end of the hydraulic ram. The bottom bracket and shuttle, when not pinned to the masts, can slide vertically up the masts. The shuttle includes features for connecting to a segment of a structure.

A pneumatic lifting device includes a base, a first mast attached to the base, and a second mast attached to the base opposite the first mast. The first mast has a first rail extending therealong, and the second mast has a second rail extending therealong. A lift platform is operatively coupled to the base. The platform includes a first pair and a second pair of bearings coupled thereto so as to move in conjunction with the lift platform. The first pair of bearings is operatively coupled to the first rail so as to enable the first pair of bearings to move with respect to the first rail. The second pair of bearings is operatively coupled to the second rail so as to enable the second pair of bearings to move with respect to the second rail.

A chamber conveyor belt machine having a machine frame, a chamber cover with two or more columns and a lifting device for lifting the chamber cover. The lifting device may include a safety system that includes a latching rail that cooperates with a latching hook disposed on at least one of the two columns. The safety system may include one or more sensors for determining whether the lifting device is working correctly or is in a failure condition. The safety system may prevent the chamber conveyor belt machine from operating if a failure condition is sensed.

A system for manufacturing radionuclide generators includes an enclosure defining a radioactive environment. The enclosure includes radiation shielding to prevent radiation within the radioactive environment from moving to an exterior of the enclosure. The system also includes a conveyance system having a forward track and first carriages positioned on and movable along the forward track for conveying racks in a first direction. The conveyance system also includes a first walking beam mechanism magnetically coupled to the first carriages to move the first carriages. The conveyance system further includes a return track and second carriages positioned on and movable along the return track for conveying racks in a second direction opposite the first direction. The forward track and the return track form a loop.
