A cable cylinder (100) comprising a frame (1);—a pin (2) mounted on the frame and extending along a first axis (Oy);—a nut (4) engaging with the pin (2);—a first cable (10) coupled to the nut or the pin (2) and intended to be functionally connected to an element to be moved;—a motor (3) designed to rotate the pin (2) or the nut (4); characterised in that the first cable (6) comprises at least a first section (6.1) extending substantially parallel to the first axis (Ox), and the first cable (6) is designed to exert opposing forces on rotation of the nut (4) by the pin (2) or of the pin (2) by the nut (4) in order to constitute anti-rotation means so that a rotation of the pin (2) or of the bolt (4) under the action of the motor (3) causes a relative movement of the nut (4) and of the pin (2).

A robot system that simplifies a configuration and control sequence of a feed table device. The robot system includes a robot, a first table and a second table, a first feed device that feeds the first table, a second feed device that feeds the second table, an interlocking member that works the first feed device and the second feed device in synchronization with each other, and a control device that controls a first operation of the robot for a process and also controls a second operation, which is different from the first operation, of the robot for manipulating the interlocking member. The robot manipulates the interlocking member by the second operation, and thus respectively disposes the first table and the second table in a position corresponding to the process.

A screw jack system comprising of a first end plate, a second end plate, a bolt, a first nut, and a second nut. The first nut is coupled to the first end plate and allows for fine length adjustments. The second nut is coupled to the second end plate. The second nut includes an elongated barrel which receives the thread of the bolt. One or more rubber pads are secured to the first end plate and the second end plate to add length, surface tension, or a combination thereof.

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 lifting device configured with a linear bearing system operatively associated with a support system configured for raising, lowering and positioning pipes for installation, service, or removal.

A portable lifting jack has a drivable mechanism operating a jack shaft formed of telescoping lifting screws. A microprocessor controls power to selectively turn electric motor to drive the operating mechanism. An in-line current draw sensor senses electric load of the motor and communicates this to the microprocessor. One detected electrical load is an electric load spike indicative that the jack shaft has contacted a mechanical load. A potentiometer connected to the operating mechanism senses extended position of the telescoping lifting screws and communicates this position to the microprocessor, which is programmed to derive when snug contact is achieved with an encountered mechanical load and to pause operation of the electric motor. In a synchronized array of jacks, all are paused to await further operator input, which may be coordinated through a remote control.
