Robotic enabled lift concepts are described. In one embodiment, a vertical lift includes a vertically directed track assembly and linear actuator that extend between first and second levels. The lift further includes a lift platform having a continuous contact roller such as a continuous belt, for example, a platform guide assembly for engagement with the track assembly, and a motion translation mechanism mechanically coupled between the continuous contact roller and the linear actuator. A robotic drive unit can drive upon and dock with the lift platform. In that docked position, the robotic drive unit can rotate its drive wheels to raise or lower itself between the first and second levels based on the translation of the motive forces of the drive wheels through the motion translation mechanism and to the vertically directed linear actuator. Other embodiments include a lift arm, an inclined track assembly, and a lift carriage.

A lift system comprising an elongated rack and a roller pinion drive system. A preferred version has two parallel rack with plurality of rungs extending horizontally between the racks to form a ladder. A plurality of spaced apart mounting brackets are configured for affixing the ladder vertically to a stationary member, the stationary member not forming part of the invention. In this version, a drive unit retained within a carriage is mounted in proximity to the racks. The drive unit interacts with the racks to move the carriage upwardly and downwardly along the racks. A speed limiter is also disclosed that can be retained within the carriage below the drive unit and mounted in proximity to one of the racks. The speed limiter interacts with the rack to produce a breaking action if the drive unit fails, preventing the carriage to drop down quickly. Single rack and inclined rack versions are disclosed as alternatives.

A modular lifting apparatus includes a vehicle body assembly and a drive control assembly. The vehicle body assembly includes a vehicle body and a pedal component, and the pedal component is connected to the vehicle body. The drive control assembly is disposed on the vehicle body, and includes a control component, a drive component and an auxiliary guide component. The control component is connected to the drive component. The drive component and the auxiliary guide component are used to cooperate with a guide body to allow the vehicle body to move in an extension direction of the guide body.

Lifting devices for residential, public and industrial buildings and structures, and more specifically, lifting and carrying systems for maintaining building facades, having rail or mast-type guides, which are arranged on the external wall of the building and equipped with teeth, and a lifting device with a drive including a motor with a gearbox, and a toothed wheel mounted on the drive shaft of the gearbox to engage with the teeth of the guides so that, when the toothed wheel rotates, the lifting device moves along the guides. The shapes of the guides duplicate that of the building, and they are attached to the building by brackets passing through the building facade and secured to load-bearing structures of the building. The lifting device has a platform, each edge of which is hinged to a frame connecting two carriages each having a system of guiding thrust rollers supported on the guides.

An elevator plate assembly for use with an elevator system including an elevator car configured to move between levels of a building along a pathway, the assembly including: a plate configured to be positioned to cover an aperture defined by a floor of the building and to be carried by the elevator car as the elevator car travels along the pathway through the aperture defined by the floor of the building; and a sensor system configured to be communicatively coupled to a control system of the elevator system, the sensor system including a pressure sensitive device coupled to the plate, the pressure sensitive device being configured to detect the presence on an obstruction on the plate by detecting a force applied to the pressure sensitive device which is greater than a threshold force, such that, on detection of the presence of an obstruction by the pressure sensitive device, the sensor system is configured to send an alert to the elevator control system.

A tower assembly system can include a self-climbing platform that can carry a load to a determined height, which once attained, can place the load into position. A method for assembling a wind turbine can involve placing a first tower section in an upright position on a tower base and using an elevator assembly platform attached to the first tower section to elevate, position and connect subsequent tower sections until the subsequent tower sections are located directly above the first tower section in a vertical tower assembly. The elevator assembly platform can perform vertical displacement operations and lateral displacement operations with respect to one or more components of the wind turbine, such as, for example, the first and subsequent tower sections, nacelle, blades, etc.

A safety device is described that can be used on a column or a segment of a column which functions as a support of a lifting apparatus, such as a goods hoist or an elevator or a work platform, used on a construction site. Furthermore, the safety device can be used in combination with the lifting apparatus mounted on the column or the segment of a column. In addition, the safety device can be used in all vertical constructions that are modularly mounted from the bottom upward.

Methods and systems for assembling a wind turbine blade for a wind turbine, can involve performing a vertical displacement of a blade holder elevator during assembly or disassembly of a wind turbine. The vertical displacement can be performed by a hard connection or a flexible connection. The hard connection can be based on a gyroscopic stability and can include a holder operable based on an ability of a wind turbine blade to freely rotate from a hub end on two axes while being elevated or lowered.

A kit provides an elevator system defining an elevator transport axis with respect to an exposed vertical face of a vertical structure. The kit includes an elevator platform, rail segment modules having elevator rail element(s), a base structure and a rail segment stacking system. The rail segment modules can be serially stacked contiguously via the rail segment stacking system to provide a mast stack, forming contiguous vertical elevator rail(s) parallel to the elevator transport axis. The elevator platform can be transported along the mast stack via the vertical elevator rail. The base structure has a module receiving station which receives from a rail segment module source each rail segment module in turn, and feeds each one to the rail segment stacking system, allowing on-site coupling and bottom-to-top stacking of the fed rail segment modules, providing a progressively elongating mast stack, and transporting the progressively elongating mast stack vertically and progressively further away from the ground after each rail segment module is stacked thereto.
