A hydraulic lift caisson for buildings including an outer rigid pipe, an inner rigid lifting post and a plurality of threaded lifting rods surrounding the inner rigid lifting post. Also included is a base lifting plate disposed within a bottom end of the outer rigid pipe and connected to a bottom end of the inner rigid lifting post and threaded rods, an anchor plate fixed to a first end of the inner rigid pipe and including a plurality of holes extending therethrough to receive the threaded lifting rods therethrough and a jacking plate disposed above the anchor plate and also including a plurality of holes extending therethrough to receive the threaded lifting rods therethrough, and at least one hydraulic jack disposed between the anchor plate and a jacking plate to lift the jacking plate, lifting post and building.

Vessel transfer systems are provide herein. The systems include bogies, including a pivoting bogie and a rack and pinion bogie, as well as associated cradles, carriages, and power and control units. The pivoting bogie includes a first side frame, a second side frame, at least one wheel coupled with each of the first and second side frames, and a lift member coupled with each of the first and second side frames. The lift member is pivotably coupled to the first side frame. The rack and pinion bogie includes a frame and pinion gears coupled with the frame. The pinion gears can be selectively coupled with a gear rack, such as at a shipyard. Also provided herein are methods of use of one or both of the bogies and associated equipment, such as for moving vessels within a shipyard.

A device for lifting a load includes: a column with a carriage sliding along the column; a structure, which is associated with the carriage, for supporting the load to be lifted; and an actuator that moves the carriage causing the load supporting structure to rise and/or descend. The supporting structure of the load includes: a single supporting arm; a longitudinal arm, having first and second ends, which is associated with the supporting arm, at the other end of the supporting arm, so as to be rotatable with respect to the supporting arm, the longitudinal arm being telescopic at one or both ends; and arms provided at one or both ends of the longitudinal arm and which develop in a transverse, or angled, direction with respect to the longitudinal arm, the arms being provided and/or configured to be engaged by members to support and/or sustain the load to be lifted.

A drop table can provide optimized lifting operations by employing motor feedback to generate and adapt a lifting strategy that controls lifting parameters. A lifting module may be connected to a first motor and consist of a lifting controller. The first motor can be mechanically coupled to a first lifting column by a first transmission and to a second lifting column by a second transmission. A service component can be lowered with the first and second lifting columns by activating the first motor that provides motor feedback. A lifting strategy can be generated in response to the motor feedback and subsequently executed to move the service component to a servicing position.

A drop table can employ one or more shearing drive couplings to optimize lifting operations. The drop table can have a motor physically attached to a first lifting column via a first rotating input shaft and to a second lifting column via a second rotating input shaft. Each rotating input shaft is connected to the motor by a drive coupling having a shearing insert positioned between a drive shaft and a collar.

A vehicle lift includes a vehicle carrier and a pair of arms. The vehicle carrier can selectively raise and lower a vehicle relative to the ground. Each arm in the pair of arms is pivotally coupled with the vehicle carrier. Each arm in the pair of arms includes a first arm segment, a second arm segment, and an adapter. The arm segments have a telescoping relationship. The adapter is coupled with the second arm segment and is slidable along at least part of the length of the second arm segment. The adapter is capable of coupling with an accessory at a first vertical profile and a lower vertical profile to thereby allow the accessory to contact a vehicle to allow the vehicle carrier to raise and lower the vehicle.

An exemplary lifting platform for motor vehicles has four supporting arms that are pivotally mounted on a lifting device, especially on two lateral lifting columns, and the free ends of which are movable under support points of a motor vehicle being raised. The supporting arms form a first pair and a second pair of supporting arms. At least the supporting arms of the first pair of supporting arms are adjustable in length and are implemented in the form of rigid supporting arms, which are pivotable solely about their articulation points on the lifting device. The supporting arms of the second pair of supporting arms are in the form of double-jointed arms having an additional articulated joint and, in the retracted state, are typically at least twice as long as the supporting arms of the first pair of supporting arms.

A fuel tank lifting apparatus includes a first lifting apparatus including a first lifting base and a second lifting base that is connected to the first lifting base by a first actuator. A positioning mount is fixedly mounted to the second lifting base. The positioning mount is configured to support a fuel tank thereon. A powered fastening gun is fixedly mounted to the first lifting base. The first actuator raises and lowers the second lifting base relative to the first lifting base. A second lifting apparatus comprising a second actuator that raises and lowers the first lifting assembly.
