A drop table can employ a number of lifting columns respectively arranged with a nut and traveler each positioned on a rotating core with the nut separated from the traveler by a nut gap. The nut gap may be measured with a first sensor positioned within the nut and the first sensor detecting a nut gap distance with a first sensing feature. The first sensor can be changed to a second sensor that detects the nut gap distance with a second sensing feature that is different than the first sensing feature.

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 vehicle lift comprising a base, a carriage configured to receive a portion of a vehicle, and an actuator configured to vertically raise and lower the carriage relative to the base. The vehicle lift is configured to send and receive wireless signals. The vehicle lift further comprises a processor configured to (i) control the actuator, and (ii) process the wireless signals.

An apparatus for lifting a vehicle comprises at least two posts, at least two lifting assemblies, at least one actuator, and an overhead assembly. The at least two posts are configured to cooperatively raise a vehicle. Each lifting assembly is associated with a corresponding post. The at least two lifting assemblies are configured to move simultaneously to raise a vehicle. The at least one actuator is in communication with the at least two lifting assemblies. The overhead assembly is secured to each of the at least two posts such that the overhead assembly extends from one post to another post. The overhead assembly is selectively movable relative to the at least two posts between a first position and a second position.

A vehicle lift includes a hydraulic cylinder having a component that rotates as the cylinder lengthens and shortens. A sensor measures the rotation or rotational position of the rotating component, and the sensor's output is used by a controller to control the vehicle lift. In some embodiments, the vehicle lift includes a scissor or parallelogram mechanism, while others are column lifts. In some embodiments, the controller uses the sensor's output to manage the limits of travel of the vehicle lift, and in others, the controller uses it to coordinate lift operations with other lifts.

A vehicle lift includes a vehicle support member, a cylinder, and a controller. A linear transducer—such as a string potentiometer—is (preferably removably) positioned inside the cylinder. The transducer detects the position of the cylinder and sends a corresponding signal to a controller that controls the height of the support member in response to the signal. The cylinder acts on the vehicle support member through a scissor mechanism, parallelogram linkage, or straight vertical hydraulic lifting.

An apparatus for lifting vehicles includes a runway, a base, an actuation assembly, a first armature assembly, a second armature assembly, and a third armature assembly. The runway is designed to vertically lift a vehicle from a lowered position to a raised position. The runway is connected to the third armature assembly. In turn, the third armature assembly is connected to the actuation assembly, which is pivotally fixed to the base. The first and second armature assemblies also connect the base with the third armature assembly. The actuation assembly is configured to lift the third armature assembly, which is guided by both the first armature assembly and second armature assembly. In response to the actuation assembly, the third armature assembly then forces the runway from the lowered position to the raised position, thereby lifting the vehicle.
