A light weight plastic liner adapted for receipt over an aerial lift basket. The lift basket mounted on a wheeled boom or scissor lift. The liner includes a floor cover and four side covers for covering an inside and an outside of four sides of a frame on the lift basket. Also, the liner includes a removable door cover for covering a hinged door on the lift basket. Further, the liner includes a bungee cord in a bottom seam of the liner for holding the liner in place on the lift basket.

Service platforms are provided for accessing the collapsing frame of blown film extrusion apparatus. The service platforms provide an access platform capable of being placed proximate the collapsing frame of the blown film extrusion apparatus to allow for service, maintenance and/or cleaning of the apparatus.

Modular systems of platforms for use on a ground surface are provided along with methods for the use thereof. The system may comprise: a bottom platform; a booster platform; a railing; and/or a lifter. The system increases the modularity, customizability, portability, and safety of: providing a platform for standing above a ground surface; altering the height above a ground surface of a platform by providing a modular or stackable system of platforms; moving a platform from one place to another along a ground surface; supporting a toolbox above a ground surface; and providing a railing to help prevent a user from falling off of a platform.

Systems and methods relate to a operator selectable, variable-height attachment point system for a safety harness, where the attachment point is disposed on a radial support member that can be reversibly coupled to a vertical support member, and where the attachment point height can be selected by the operator by reversing a coupled orientation of the radial support member to the vertical support member.

A set of accessories for use in combination with a scaffold is comprised of at least one pair of support hooks, at least one stirrup member for facilitating stepping up or down from the scaffold, at least one material holder.

A set of accessories for use in combination with a scaffold is comprised of at least one pair of support hooks, at least one stirrup member for facilitating stepping up or down from the scaffold, at least one material holder.

An adjustable platform extension bracket for work platform systems comprises a post member having two posts joined by a plurality of positional structures. A first connection portion forms a first channel such that the first connection portion is symmetrical along an axis parallel with and passing through the channel. The post member is slidingly engaged in the first channel such that at least one of the positional structures is positionable in the channel. The bracket does not require any diagonal support. The dimensions of work platforms, particularly suspended work platform systems, may be extended using the adjustable platform extension bracket.

A falling prevention structure can be stably connected to an attached lift scaffold body and is provided with a hinge point in the middle. The control arm is on one side of the hinge point, and an extension portion of the control arm can be connected/matched with a lifting structure of the attached lift scaffold. An operating arm is on the other side of the hinge point, an extension portion of the operating arm is provided with a transition structure and connected to a falling prevention pin by the transition structure. The falling prevention pin is provided with an elastic restoring structure and is capable of extending and retracting, and the extending falling prevention pin can be inserted into a clamping and hanging structure in a falling prevention structure directly or indirectly fixed to a building object.

A lock mechanism (10) for a scaffolding clamp or coupler (33) having a threaded rod (15) and a securing nut (14) is disclosed. The mechanism deters unauthorised removal of the securing nut and has a locknut (12) engageable with the threaded rod and having an unconventional drive mechanism (17). The mechanism also has a substantially cylindrical hollow sleeve (13) with a cylindrical interior dimensioned to surround the securing nut and locknut. The locknut has a main body with a tapered nose (21) able to bear against the securing nut and an annular recess (23). The sleeve interior has an inwardly projecting substantially annular flange (26) through which the nose can be forced to locate the flange in the recess and thereby retain the sleeve on the locknut. In addition, the sleeve has an exterior which is smooth and devoid of projections and recesses, and an axial length greater than the combined axial lengths of said securing nut and locknut, to thereby shield both the securing nut and the lock nut. A cup shaped shield (40) and cap (45) for masonry bolts (37) is also disclosed.

A scaffold rack may have a first side and a second side. An upright portion may be located between the two sides. The first side may have at least one pair of scaffold frame tubes adapted to selectively secure at least scaffold frame. The second side may have a first arm adapted to selectively support at least one walkboard thereon and a second arm adapted to selectively support at least one scaffold bracket thereon.
