The disclosed modular dozer platform provides systems and methods for safely accessing a platform for mounting a mobile piece of mining equipment. The disclosed systems and methods comprise a platform with modular frame, a plurality of ground engaging members supporting the frame and one or more sets of stairs providing access to the modular frame. In practice, the mobile piece of mining equipment is positioned in a central location and the modular frame sections are positioned around the mobile piece of mining equipment.

A brake/ballast assembly for a movable structure. The brake/ballast assembly includes a movable brake/ballast plate movable between a movable brake/ballast plate first position in which the movable brake/ballast plate is positioned proximate the fixed member and a movable brake/ballast plate second position in which the movable brake/ballast plate is spaced from the fixed member. An engagement member is connected to the movable brake/ballast plate. The engagement member is movable between an engagement member first position and an engagement member second position. When the engagement member is in the engagement member first position, the movable brake/ballast plate is provided in the movable brake/ballast plate first position allowing the movable structure to be moved along a surface, when the engagement member is in the engagement member second position, the movable brake/ballast plate is provided in the movable brake/ballast plate second position preventing the movable structure from moving relative to the surface.

The claimed invention relates to a folding utility scaffold that greatly reduces the space requirement for shipment when the utility scaffold is in the folded configuration while maintaining or increasing stability. The scaffold includes first and second ladder frames and a hinge assembly interconnecting the ladder frames. The scaffold comprises first and second ladder frames and a hinge assembly interconnecting the ladder frames. The hinge assembly enables movement of the scaffold between an unfolded configuration in which the ladder frames are spaced apart and a folded configuration in which the ladder frames are disposed side by side, i.e., with the ladder frames touching. The ladder frame and hinge assembly are designed to avoid interference between components of the hinge assembly and components of the ladder frame in the folded configuration so that the ladder frames can be disposed in side-by-side relation in the folded configuration.

A scaffold having a structure assembly. The scaffold has a frame attached to the assembly. The frame having a deck upon which a user can stand that is disposed inside the rectangle. The deck has a plans table. The plans table has a closed position in which the plans table is flat and can support a weight of a user standing on the plans table, and has an open position in which the plans table is at an angle on which plans, drawings or documents can be placed on the plans table for viewing by a user standing on ground. A scaffold having connectors. A method of using a scaffold. A method for connecting a first scaffold to a second scaffold. A method for making a scaffold with connectors. A method for making a scaffold having a plans table.

The claimed invention comprises a tool shelf for a multi-function scaffold comprising two spaced apart ladder frames supporting a platform and a guard rail mounted to the platform. The tool shelf is specially designed to mount to either the ladder frame, or to the guard rail system. When the platform is adjusted to the maximum height, the worker can mount the guard rail system so that the items placed on the tool shelf will be within reach without bending over. When the platform is lowered, the tool shelf can be mounted to the ladder frame.

An illustrated view of an exemplary scaffolding for providing access to high areas is presented. The scaffolding is useful for positioning the scaffolding at a desired height dependent on the need of the user. Also, the scaffolding provides a quick and easy way to erect, reduce the size of and reposition or re-height the scaffolding. The scaffolding is cost effective and re-uses a commonly owned tool to create a more efficient working with the scaffolding. The scaffolding is useful for framing, hanging and finishing drywall, painting, plumbing, electrical, etc.

A side rail assembly useful for securing a deck of a scaffold comprises a side rail configured to be supported between two ladder frames in first and second orientations. The side rail includes first and second support surfaces for supporting the deck in the first and second orientations, respectively. First and second vertically aligned slots are formed in respective opposing surfaces of the side rail. The side rail assembly further comprises a locking pin assembly comprising a shaft, a locking tab, and a biasing member to bias the locking tab into engagement with the deck and secure the deck against one of the support surfaces of the side rail depending on the orientation. The locking pin assembly is configured to be removably engaged with the first and second slots of the side rail in both the first and second orientations.

Various implementations described herein are directed to a load bearing ledger fitting, a modular header beam, a perimeter safety deck, a multi-purpose bearing plate, and a mega-shore bearing plate of an integrated construction system.

A lightweight, multi-function scaffold includes an adjustable height platform that slidably mounts between two ladder frames. The side rails of the platform are reversible so that they can be mounted between the ladder frames in either a first orientation or in a second orientation. In the first orientation, the adjustable height platform is vertically movable between a first threshold and a maximum height. In the second orientation, the adjustable height platform is vertically movable between a second threshold and a minimum height. The ranges of movement in the first and second orientations may overlap.
