A climbing device is proposed having at least one climbing rail for adjusting and/or climbing a scaffolding and/or a formwork and/or a platform, at least one climbing shoe being arranged on the climbing rail, at least one hydraulic cylinder comprising at least one drive piston, arranged in a cylinder housing, and having a hydraulic fluid being provided for raising the climbing shoe and/or the climbing rail and/or the scaffolding and/or the formwork and/or the platform, which at least partially avoids or at least reduces the disadvantages of the prior art. According to the invention this is achieved in that the hydraulic cylinder is embodied as a hydraulic unit, the hydraulic unit comprising at least one hydraulic tank for storing hydraulic fluid, an electric motor and a hydraulic pump driven by the electric motor for pressurizing the hydraulic fluid.

The invention relates to a holder (1) for a guide shoe (14) of a climbing system for concrete formwork having a hold-down (2) which can be fastened to a floor, and a slide part (3), which is movably guided in the hold-down (2), such as in the form of a support arm. According to the invention, the holder (1) is designed having a self-locking drive, such as a screw drive (10) for moving the slide part (3), which secures the slide part (3) against unintentional movement.

A break-away canopy assembly configured for use with a work platform in an elevator hoistway is provided. The break-away canopy assembly includes a plurality of spaced apart canopy posts in a substantially vertical orientation. A first support framework is connected to one or more of the spaced apart canopy posts. A second support framework is connected to one or more of the spaced apart canopy posts and opposes the first support framework. The first and second support frameworks each have connected first and second extension assemblies. One or more roof sections span and are connected to the first and second support frameworks. The first and second extension assemblies of the first support framework and the first and second extension assemblies of the second support frameworks are each configured to separate from each other in the event of an uncontrolled descent of the work platform.

An apparatus includes a first platform, a second platform disposed above the first platform, a scaffolding connecting the first and second platforms including an upper support beam, a middle support beam, and a lower support beam, and a cable attached to the upper support beam. The lower support beam supports the first platform. The middle support beam supports the second platform. The upper support beam is disposed above the second platform.

To ensure maintenance operations for an architectural structure using a mast climber without any limitation on the stability of a mast and locations where a mast can be erected. A side wall 101 of an architectural structure 100 is fitted with a fixing member 130 at a level higher than the ground 500. The fixing member 130 is fitted with fixture studs 132. A mast 200 is erected on the fixing member 130 with its lower end secured to the fixture studs 132. A climbing work platform 210 that travels up and down the mast 200 is fixed to the mast 200. A worker performs maintenance operations on the climbing work platform 210.

Embodiments described herein relate to a self-extending/retracting gate for a platform. In one embodiment, safety gate includes a housing that extends laterally from a back support attached to the platform. The gate includes a sliding member that is operable to retract at least partially into the housing toward the back support to substantially conceal the sliding member within the housing and provide an opening beyond the housing for users to access the platform and to extend from an opening of the housing away from the back support to block access to the platform while the housing supports the sliding member. The gate includes a gate movement assembly within the housing between a rear portion of the sliding member and the back support. The gate movement assembly is operable to cause the sliding member to extend from the housing and retract into the housing according to a height of the platform.

A scaffolding system can include a first platform and a second platform adjustably connected to a plurality of tower extensions. Fixing members coupled to the plurality of tower extensions may fix a separation distance between the first platform and the second platform. One or more dimensions of the first platform and one or more dimensions of the second platform may be adjustable. A position of the first and second platforms along the plurality of tower extensions may be manually adjustable. An extendable wall may be connected to outer edges of the first and second platforms.

This system, for performing maintenance of at least one part of an object, is provided with: at least one rope holding device which is configured to move up to said at least one part of said object and to hold at least one rope at said at least one part of said object; and a maintenance device which, configured to perform the maintenance of said at least one part of said object, is configured to move on the aforementioned at least one rope, held by the at least one rope holding device, to said at least one part of said object and to move on said at least one part of said object.

An exterior wall repair device includes a travel path body, a carriage having a traveling part capable of traveling on the travel path body and winch devices, a repair device main body having a gondola suspended and moved up and down by the winch devices, a manipulator arranged in the gondola and performing repair work, a shooting part capable of shooting images of the state of working by the manipulator, a vacuum device for detachably fixing the gondola to an exterior wall surface, and a belt having both end portions fixed to attaching/detaching means of the fixing device and wound around a drive part of the manipulator, and a remote control part having a monitor on which an operator can see an image from the shooting part and operation gloves operated by the operator and capable of remotely operating the manipulator in synchronization with the manipulator.

The present disclosure relates to a height accessible working platform. The disclosed working platform generally comprises a frame attachable to a lifting system for being moveable along the vertical axis and suspended thereto;a cradle; a first arm structure having a proximal end terminated to the frame and an distal end attached to the cradle, the first arm structure being extendable and retractable to displace the cradle respectively away from and closer towards one of lateral sides of the frame along a first axis substantially perpendicular to the vertical axis; and a counterweight mechanism mounting at one lateral side of the frame opposing to the cradle, the counterweight mechanism being configured to balance the working platform corresponding to displacement of the cradle along the first axis.
