Abstract: A suspension lift apparatus includes a platform, a plurality of direction changing sheaves and lifting sheaves mounted to the platform, a plurality of cables and a lifting mechanism positioned on the platform. Ends of cables mounted above the platform extend through the sheaves and are coupled at the opposite cable ends to the lifting mechanism disposed on the platform.

The suspension lift apparatus may include legs to provide an overhead anchor point.

Abstract: In a vehicle braking system for stabilizing vehicle behavior: a motor control unit determines whether or not the motor control unit receives a drive forbid signal from a yaw-moment control unit, when the motor control unit receives a drive instruction signal from a vehicle-behavior stabilization control unit. The motor control unit receives the drive forbid signal when the yaw-moment control unit performs yaw-moment control. The motor control unit forbids prepressurization using a slave cylinder, when the motor control unit receives the drive forbid signal.

Abstract: Disclosed herein is a chassis assembly device of a vehicle assembly line used to assemble a plurality of components on a vehicle body in an assembly process including a main lift disposed on a carriage and configured to move along a carriage line, support a vehicle body, and lift upward or downward; and a sub lift unit disposed on the carriage to lift the plurality of components to an assembly position of the vehicle body.

Abstract: A power ramp for a vehicle and a control method thereof are disclosed.

Abstract: A pallet positioner includes a support frame that consists of a main upright structure with a pair of spaced, parallel outriggers extending horizontally at ground level. The distal ends of the outriggers are connected by a low-profile ramp. The upright structure includes a pair of vertical guide masts rigidly mounted on a horizontal base bracing the proximal ends of the outriggers. A pneumatically and hydraulically controlled, or electrically and hydraulically controlled, cantilevered carrier with a rotatable platform is mounted for vertical motion along the vertical guide masts. When the carrier travels downward, the carrier stops automatically at a level above the outriggers and must be manually restarted. A braking system under the platform prevents rotation thereof at ground level.

Abstract: The invention relates to a method and a device for monitoring a lifting system (11) for lifting loads, particularly vehicles, in which for lifting a load (14), the lifting movement is initiated by a starting phase, and lifting devices (12) are individually driven in the starting phase. Load holding means (18) of the lifting devices (12) are raised until a pre-set minimum load is detected by the pressure sensor (24), and the load holding means (18) are raised by a pre-selectable displacement distance in a load recognition phase of the lifting process following the starting phase, and after the pre-selected displacement distance is passed through, a load inquiry is carried out and the determined load is stored as a reference value for the further lifting process.

Abstract: In a method for monitoring a stationary condition of a drive device, a monitoring device provides the drive device with a temporally varying monitoring signal which, when a sensor device connected to the drive device functions properly, modulates a sensor output signal of the sensor device in accordance with the monitoring input signal. The monitoring device receives the sensor signal and monitors it for the presence of a corresponding signal component. In the absence of such a signal component, the monitoring device controls a safety device which converts the drive device into a safe state. When the drive device is controlled by means of at least two phase-shifted current regulators, it is possible for the monitoring device to monitor an output signal of at least one of the current regulators for constancy and to control the safety device when the output signal of the at least one current regulator changes.

Abstract: A lifting platform for vehicles having at least one column, at least one support arm shiftable on the column by vertical guides and having supports. The lifting platform also includes a prime mover having switching and control elements and a transmission disposed between the prime mover and the associated support arm, the transmission having at least one flexible traction cable coupled to a rotating member positioned at the upper end of the respective column and to the associated support arm.

Abstract: Vehicle lifting device comprising a number of columns, guides on each column for guiding a carriage for substantially vertical displacement along the column, which carriage bears vehicle supports. Lifting supports engage on the columns and the carriage. The lifting supports are connected to a motor, and a synchronization system for causing the carriages of all columns to run synchronously. The lifting supports of each column are provided with their own motor.

Abstract: An operating device for a lifting platform, particularly for a vehicle lifting platform, includes a housing including a plurality of operating elements for operating the lifting platform. The housing is arranged in the floor in a sunken manner and includes a cover disposed on the floor level, in which the operating elements formed as foot switches are disposed.

Abstract: A vehicle lift assembly prevents accidental slippage of a vehicle therefrom. The vehicle lift assembly comprises a plurality of vertically disposed posts and a runway slidably coupled to the plurality of vertical posts. A hoist system supplies the force necessary for elevating the runway along the plurality of posts. A sensor arrangement detects whether the runway has tilted beyond a predetermined angular displacement. A lift control circuit controls the hoist system to elevate the runway selectively in a prescribed direction, and suspends operation of the hoist system, when necessary, to prevent the vehicle from accidentally sliding off the runway.

The elevation system further includes a control device which is electrically connected to the drive assemblies and is operational in a first mode wherein the elevator platforms may be raised and lowered independently of each other and a second mode wherein the elevator platforms may be simultaneously raised and lowered.

Abstract: A fallproof safety parking apparatus including a main body having a transverse beam and a lateral beam on which a detector and a detecting means are respectively disposed beside driving chains. The detector has a resilient pressing rod and the detecting means has a resilient pressing post for abutting against the chains without affecting the operation thereof. In case any section of the chains is broken apart, the resilient pressing rod of the detector or the resilient pressing post of the detecting means immediately bounds out from the broken section of the chains to actuate a microswitch of the detector or detecting means, making a fallproof means powered off. At this time, a brake block of the fallproof means is inserted into an insertion hole of a fixing lever of the main body and locked therein so as to instantaneously prevent an upper parking platform from straightly falling down. Two pairs of steel cables are disposed on the beams of the main body to help in holding the upper parking platform.
