Penstock internal maintenance system, the penstock comprising an inclined portion between upper and lower ends, the upper end comprising a water collecting chamber and at least one gate bearing structure allowing a gate to close the penstock tight of water, at least the gate bearing structure adjacent to the water collecting chamber forming a vertical pit. The system comprises a set of units assembled in an assembled configuration and separated in a dismounted configuration, and comprising an anchor unit, a launching unit and a penstock inspection platform unit, the units in the dismounted configuration being configured to enter the penstock through the gate bearing structure adjacent to the water collecting chamber, the units are assembled when located in the penstock, the anchor unit being further configured to be slidingly received and retained in the gate bearing structure, the anchor unit having two lateral edges being guided and retained in two vertical lateral grooves of the gate bearing structure. In the assembled configuration, the penstock inspection platform unit is parked on the launching unit when in a parking state and the penstock inspection platform unit being away of the launching unit when in an operation state, the penstock inspection platform unit being linked to the anchor unit through the launching unit with cables allowing the penstock inspection platform unit to move away passively along the incline of the penstock by unwinding the cables or, reversely, move toward the launching unit by winding the cables, the launching unit being fastened to the anchor unit.

In a ladder assistance device, a cable pulled by a controlled driving apparatus is laid in a loop along the height of the ladder, the user being attached to the cable by a lanyard, a sensor element detecting movements along the ladder, a control element controlling the driving apparatus. A remote control activates or deactivates assistance and allows user weight input, the remote control remaining in the reach of the user and including a stop button deactivating assistance and two activation buttons for activation of assistance, one each for “up”/“down”. A memory stores sets of control values for assistance level(s) for each direction of movement, corresponding to at most two levels in the steady state of the assistance. The program of the control element allowing: the selection that corresponds to the user weight, the activation which is only obtained by the activation buttons of the remote control.
A portable davit base for removable attachment to a rooftop davit pedestal having a mounting plate includes two opposed side plates and two metal transverse supporting members for mounting on the mounting plate and secured thereto with connector pins that extend underneath edges of the mounting plate on opposite sides of the davit pedestal. The opposed side plates have vertically spaced apertures for inserting davit mast supporting pins for pivotal mounting of a mast on the assembly. A davit arm connected to the mast is rigidly attached to the portable davit mounting assembly for use in suspending scaffolding over the side of a building.

A system and method for a scaffold deck with a fall arrest assembly is disclosed. The fall arrest assembly comprises a deck structure (102) and a rail assembly (122) for permitting an individual to tie-off in a manner that permits the individual with a range of motion along the deck structure. The fall arrest assembly further includes an uplift hook mechanism (120) connected to or otherwise installed on the deck structure such that the uplift hook mechanism is employed for both securing the deck structure to and releasing the deck structure from at least one supporting member. A plurality of deck hooks (118) connectable to or otherwise installed on the decking structure for connecting the decking structure to the supporting member is additionally provided. A deck latch assembly located connected to the uplift hook mechanism additionally facilitates connection of the deck structure to a second deck structure.
