A system is used for lifting a heavy oversized structural element. At least two opposing lifts are placement adjacent opposing sides of the element. Each lift includes a base, a tower, an elevator, and an actuator. The tower extending vertically from the base, and the elevator is disposed on the tower. A support extends from the elevator outward from the tower to engage a point on the element. A guide of the elevator is configured to ride along a rail of the tower. The actuator is connected to the elevator and is configured to move with the elevator vertically along the tower. The actuator can include a strand jack disposed on the elevator. Hydraulic operation of the stand jack moves the jack and elevator along a strand extending along the tower. The arrangements of the lifts leave space below the raised element free for access to other operations.

The present invention relates to a lifting system and method for lifting a vehicle, wherein the lifting system including one or more lifting devices and: a frame with a carrier configured for carrying the vehicle; a drive for driving the carrier in at least one of the ascent or descent of the carrier; and a controller including an indoor positioning system with a transponder, wherein the transponder is provided on or at the carrier such that the controller determines the location and the height of the carrier in at least one of the ascent or descent of the carrier.

A three-level vehicle lift. The lift includes a four-post configuration in which each post includes a pair of vertically extending, side-by-side channels. Two platforms are provided. Each includes a carriage configured to engage a respective one of the channels in each post and a hydraulic actuator and lifting cable system disposed within the platform for lifting the platform. An actuation system having a single hydraulic pump is provided with a valve for selectively supplying hydraulic power to either an upper- or a lower-platform hydraulic circuit. The simplified lift and actuation system configuration reduces manufacturing, shipping, installation, and materials costs and complexities.

A lift assembly including a lifting structure, a lifting arm, a yoke structure fixed to the lifting structure, a pin pivotally coupling the lifting arm with the yoke structure, and an integrated anti-rotational assembly associated with both the yoke structure and the pin. The lifting structure can actuate relative to the ground between a lowered position and a raised position. The lifting arm is configured to actuate with the lifting structure between the lowered position and the raised position. The integrated anti-rotational assembly can inhibit rotation of the pin relative to the yoke structure about the longitudinal axis of the pin.

An intelligent platform may employ a unitary platform positioned between articulating legs with each articulating leg connected to a leveling module. The leveling module can be configured to execute a leveling strategy that involves extending at least one articulating leg to establish the unitary platform in a level orientation relative to an underlying, non-level terrain.

A lifting column can provide optimized performance with a nut gap system that efficiently and precisely measures a nut gap during lifting operations. The nut gap system can have a rotating core onto which a nut and traveler are positioned. The nut can be separated from the traveler by a nut gap that is monitored by at least one sensor that continuously extends through the nut to access the nut gap.

A lift system includes a lift structure and a lift structure actuation assembly. The lift structure can actuate between a lowered position and a raised position. The lift structure actuation assembly includes a hydraulic cylinder operably coupled with the lift structure, a motor, a hydraulic pump powered by the motor, and a flow control assembly that can limit hydraulic fluid exiting the hydraulic cylinder to a maximum volumetric flow rate. The hydraulic pump can pump hydraulic fluid into the hydraulic cylinder in order to raise the lift structure. The lift structure actuation assembly can lower the lift structure in a fast descent mode and a slow decent mode. In the slow descent mode, the hydraulic pump pumps hydraulic fluid toward the hydraulic cylinder such that the hydraulic fluid exits the hydraulic cylinder at a slower volumetric flow rate compared to the maximum volumetric flow rate.

A vehicle lift system includes a vehicle lift operable to lift a vehicle to be serviced by a technician. The vehicle lift includes lifting components for engaging and lifting the vehicle at liftable structures of the vehicle. Electrodes are positioned on the lifting components of the vehicle lift. The electrodes are operable to make electrical contact with the liftable structures of the vehicle when the lifting components engage the liftable structures. A voltage detector system is in electrical communication with the electrodes. The voltage detector system is operable to detect voltages at the electrodes capable of harming the technician. The voltage detector system is also operable to send a warning signal to the technician indicating that a harmful voltage has been detected on the electrodes when the electrodes make electrical contact with the liftable structures of the vehicle.

A cord protector comprising at least one elongated body and at least one coupler. The elongated body has a base and a lid, and has a cavity in each of the first end and second end of the elongated body. The base has a channel extending between the first end and the second end in which a cord may rest. The channel may have one or more ridges. The lid is configured to insert into and cover the channel, and may have one or more grooves sized and shaped to receive a ridge. The coupler has a leading end and a trailing end. The leading end is sized and shaped to mate with the cavity of the first end and the trailing end is sized and shaped to mate with the cavity of the second end. Multiple elongated bodies can be coupled together through the use of the couplers.
