Apparatus for transporting a device along a tower, which comprises a rail susceptible of being fixed to a tower and extended according to a substantially rectilinear guide direction, and a trolley slidably constrained to the rail and adapted to support a device to be transported provided with at least one power cable. The rail comprises at least one hollow shaped profile with elongated form, which is longitudinally extended according to the guide direction between a lower edge thereof and an upper edge thereof, and is provided with an internal surface which defines a guide seat in which the trolley is slidably housed and in which the power cable of the device is susceptible to pass.

An apparatus designed for climbing poles, trees and other such columnar objects. The apparatus is a remote-controlled work station that provides a scaffold for mounting semi-robotic articulated arms and video cameras. The articulated arm has a quick-release coupler on an end thereof that is able to repeatedly and releasably couple attachments thereto, such as saws, blades, and other pruning objects. The device includes an expandable frame that may be opened and closed to fit around the vertical structure to be climbed. The frame has horizontal and vertical supports, drive system compression supports, and wheels. A drive system is mounted to each of the drive system compression supports. The drive system includes motorized tracked-climbers that are maintained in contact with the vertical structure to be climbed via adjustable independent suspension. The suspension uses adjustable spring shocks and drive system slide rails to connect the frame to the drive system.

An elevator system comprising an elevator cabin, and a traction wire rope for driving the elevator cabin and/or a safety wire rope, wherein the elevator system further comprises an upper transverse element provided above the elevator cabin and adapted to be guided along the traction wire rope and/or the safety wire rope, and a support structure which is adapted to support the upper transverse element and substantially impede its movement in a downwards direction and in a horizontal direction, and to allow movement of the upper transverse element in an upwards direction.

A supersized elevator for use in building a large ship or an offshore plant is provided. The supersized elevator includes an elevator structure (100), an elevator cage (200) configured to accommodate passengers and heavy articles, a counterweight (230) configured to maintain a weight balance with the elevator cage (200), a wire rope (220) configured to interconnect the elevator cage (200) and the counterweight (230), and a winding machine (210) configured to wind the wire rope (220). A wind shield module (800) configured to prevent a tail cable (910) from being affected by a strong wind is vertically installed on one inner side surface of the elevator structure (100).
