Platform-Supported Boiler in-Furnace Scaffolding and Lifting Systems
SKYFFOLDING™ Systems, A flagship brand of KLES, first off build up 'Hydraulic lifting system' on the topmost of the boiler (Heavy girder), and then platform-supported pendant scaffolds assembled at ground/Zero level are lashed down with wire ropes and lifted up at intervals to systematize the upper & the lower scaffold lifting system each, whereupon stepping up work efficiencies by way of stabilization of the system with minimized swaying, while proactively warding off workplace disaster arising from the chain reaction triggered by a failure of a member component in the case of the conventional upright scaffold. Currently, the system has been adopted and operated in most domestic thermal power plants in Korea, over 98%.

Scenes of the collapse of the existing system
On the heavy girder in the penthouse of the boiler, the strand lift jacks are installed, and then thereto connected by the strand down to the platform which supports the upper and lower parts of the system, so that all the loads can be supported from the top.
The structural safety and stability have been secured by verifying the stress and strain amounts at the upper support points when the loads are applied to downward scaffolds. In addition, the working loads on the scaffold have been figured out and reviewed to the extent to work by 20 persons in one layer of all 4 sides, or by 5~6 persons on each side.
The loosen-proof safety design of wire clamp
The more load is applied, the farther the clamp tightens the wire rope, therewith beefing up its clamping force.
Walk plate designed to ensure easiness and convenience for the working, together with staircase put up between layers in consideration of mobility. In an effort to reduce manufacturing costs and improve installation conveniences, the prefabricated system scaffold components and members are used in.
Perfectly improving work efficiencies in detail inspection and repairs by way of putting up walk plates on all fronts in four sides of the water wall.
The upper scaffold lifting system added up
Geared up to be workable for either planned preventive maintenance or contingency maintenance on the section of SH Platen and Division.

Smart Scaffolding Safety-Management System
This Smart in-furnace scaffolding safety-management system has been designed and developed for the safety and security of the workmen who are working inside the dark and noisy furnace. Organizing the system coupled with SKYFFOLDING™ Systems, you can efficiently manage the safety of the scaffolding along with the wellness of workers in the furnace exposed to many kinds of dangers, by means of installing ‘the load measurement’, ‘the displacement measurement’, ‘the workman monitoring [IR/IP camera]’, and ‘the alarm modules’. In addition, it can be extensively applied to various construction and maintenance environments such as system scaffolding.
Realtime monitoring of load distribution onto in-furnace scaffolds, wherewith preventing any accidents on account of the unbalanced load across the system.
Measuring the displacement of the support structure (Platform), in order to monitor any outbreak of deformation or displacement anomaly.
Network screening all four sides and corners throughout the boiler so that you can figure out the location and status of the workmen in realtime in case he or they are left in the furnace, by putting into use IR/IP cameras featuring pan & tilt - zoom in/out - infrared thermal image - motion detection functions all together.
Alarming the danger to workers staying in the furnace when any contingency signal(s) is detected, including overloads in the rated or work load on in-furnace scaffolds.
Compiling and storing measured load and displacement data, with the server and client software configured.
Activating the alarm system when abnormal load or displacement is detected, so as to warn the workers of such a danger. Managing load and displacement trends and system errors, by referring to history inquiry function.
Detecting in realtime if any outbreak of eccentric load or abnormal displacement of the scaffold support structure, so as to alarm the danger to in-furnace workers when such an abnormal signal(s) takes place; which shall relieve the workers from worksite anxiety as well as beef up supervisory usability. Besides, the system can check if any presence of residual workers inside the furnace workplace, after installing/disassembling the scaffolding or repairing the boiler putting the scaffold to use.
Safety Plus is configured with the Server system and the Client system. The Server collects, stores, and manages the load and displacement data in realtime. Particularly, on the Safety Plus Viewer program installed in the Client system, the user can monitor in realtime the scaffold state in 3D, and the whereabouts of the checked-in workers, alongside the functions of thermal image verification, data history trend analysis, alarm history trace management, etc.
Realtime monitoring of the loads acting on the scaffolds and the displacements of the boiler tube makes it feasible to take immediate action in response to the outbreak of abnormalities across the system
