A trailer lift that rises to high levels that may tilt for loading and unloading. The trailer lift includes a lift-and-tilt mechanism, a trailer base, and a trailer platform. The lift-and-tilt mechanism includes a lower-strut link, an upper-strut link, a support member, a lower lift cylinder, and an upper cylinder. The lower-strut link and the upper-strut link are pivotably and terminally attached to each other. The support member is positioned offset to the lower-strut link and is pivotably attached to the upper-strut link to guide the upper-strut link. The trailer platform is terminally and pivotably connected to the upper-strut link. Similarly, the trailer base is pivotably and terminally connected to the lower-strut link and the support member. The upper lift cylinder is pivotably mounted in between the upper-strut link and the trailer platform. The lower lift cylinder is pivotably mounted between the upper-strut link and the lower-strut link.

A concrete patching robot has a multi-axis robotic manipulator mounted on a powered, movable, platform that can be raised and lowered to access the underside of structures that may be substantial distances above the ground, for example, the underside of an elevated highway. The entire assembly is maneuverable under the work area and the platform may be raised to access the concrete. Once the work area is in reach of the arm, the device is able to use numerous tools to complete essential steps to repair the concrete.

An authentication module may be internally or externally installed on a lift control of a vehicle lift and allows new and updated features to be added to the vehicle lift without requiring a connection to a local or cellular network. The authentication module connects to one or more other electrical components of the lift control to allow for the exchange of data. A module containing software and configurations for enabling a feature may be removably attached to the authentication module, which uses the stored configurations to verify and enable the associated feature. The use of enabled features may be persistently tracked by the authentication module even in the absence of an external power source or network connection, and may be disabled by the authentication module if the feature use expires or is exhausted.

A lifting system for lifting and/or lowering loads having a lifting apparatus which is suitable for conveying loads along a lifting direction from a first transfer position into a second transfer position and along a lowering direction from the second transfer position to the first transfer position, and a conveyor apparatus which is suitable for taking on, at the first and/or the second transfer position, the loads conveyed by the lifting apparatus. The conveyor apparatus has at least one holding pendulum which is pivotable into a holding position, wherein the lifting apparatus has at least one holding receptacle for the holding pendulum, wherein the holding pendulum, in the holding position, can be placed in engagement with the holding receptacle, by a movement of the holding receptacle in the lowering direction, such that a movement of the lifting apparatus in the lowering direction is blocked, and/or the holding pendulum, in the holding position, can be placed in engagement with the holding receptacle, by a movement of the holding receptacle in the lifting direction, in such a way that a movement of the lifting apparatus in the lifting direction is blocked. The holding receptacle has a first guide track, wherein the first guide track is designed so as, during a movement of the holding receptacle along the lifting direction or the lowering direction, to move the holding pendulum into a first position in which the holding pendulum cannot be placed in engagement with the holding receptacle.

A DC motor drive comprises an AC to DC exchange system, a circuit protection system and a motor start system connected to a DC motor. The AC to DC exchange system is connected to an AC power supply and is configured to convert AC power to DC power. The circuit protection system is connected to the AC to DC exchange system. The circuit protection system includes a resistor connected in series with a diode. The motor start system includes a first switch and a second switch. The first switch is connected across the DC motor and the second switch connected in series with the DC motor. When the AC supply is applied to the DC motor drive of the auto lift, the AC to DC exchange system converts the AC power to DC power which starts the DC motor by means of the motor start system.

A pick and place apparatus, adapted for a carrier, includes a housing connected to the carrier, a lifting assembly movably disposed on the housing, and a pick and place assembly movably disposed on the lifting assembly. A movable direction of the pick and place assembly relative to the lifting assembly is perpendicular to a movable direction of the lifting assembly.

A booth for photographing or inspecting a vehicle includes walls that bounding a planar stage, each of the walls has a first portion and a second portion, the first portion has a first length and extending up from the planar stage. A first end of the first portion forms a first obtuse angle with the planar stage inside the booth, the second portion has a second length and extending up from a second end of the first portion. A first end of the second portion forms a second obtuse angle with the second end of the first portion inside the booth. A platform is also suspended above the stage. A lighting source is positioned on the platform. The lighting source is configured to direct light toward the second portion of each of the walls.
