A multi-level deck system for a blowout preventer and a method, of which the system includes a first deck positioned at least partially around and coupled to the blowout preventer, a second deck positioned at least partially around and coupled to the blowout preventer and vertically spaced apart from the first deck, and a third deck positioned at least partially around the blowout preventer and vertically spaced apart from the second deck.

Currently, a drywaller on the ground physically lifts the 100+ pound sheet of drywall up to the person on the scaffold, who then has to lift/pull the 100+ pound sheet of drywall up onto the scaffold to hang on the wall. Both people must use their arms, shoulders and back to lift the drywall, and the man on the scaffold sometimes uses his foot to slide the drywall up onto the scaffold. The DSR eliminates this unsafe lifting procedure by providing a rolling mechanism to roll the sheet of drywall instead of lifting. It takes most of the heavy weight of the drywall off the workers, making it safer and easier, which may reduce the number of arm, shoulder, back and foot injuries from manually lifting the heavy sheet of drywall from the ground up onto the scaffold. It is an inexpensive way for drywall companies to more likely than not reduce the number of workplace injuries and worker's compensation claims.

A rack and a hoist system. The rack is L-shaped with a first planar floor/leg and a second planar floor/foot, which is a solid plate. The first floor has three pairs of wheels with the middle pair larger than the other pairs and a mount to couple to the hoist via a hooked line that couples to a double-hooked line that hooks into apertures through paired mounting plates near the top end of the leg. The foot includes a tag-line mount from which a tag-line may be mounted to help guide movement thereof using the hoist. The foot includes wheels such that when the first floor is tipped up while being lifted, the wheels of the foot engage with the surface while the wheels on the leg are disengaging. There are flanking posts, strap structures, and flanking plates that help to secure the load (e.g. rebars, pipes, and sheet rock).

Work platform, comprising an elevatable platform deck provided with a rail system having one or more rails extending in a longitudinal direction along a trailing edge of the deck; a trolley engaging with the one or more rails and configured for being moved in the longitudinal direction; and a crane device mounted on the trolley, configured for lifting and moving objects above the platform surface.

A hoist system includes a motor with a drive shaft connected to a traction sheave, traction drum, or pinion. The hoist system further includes a compartment configured to at least partially enclose a direct current power supply such that the direct current power supply is electrically connected to the motor. The motor is configured to receive an input and convert the input to movement of the drive shaft as an output, and the motor is configured to be coupled to a load such that movement of the drive shaft moves the load.

A runback backstructure access system for removably providing access between building floors of a building structure. The system includes: first and second tower legs with first and second rosette attachment connectors; a first landing beam mountable between the first and second tower legs; first and second landing beam support connectors connectable respectively to the rosette attachment connectors; at least one building support connector for connecting the first landing beam to the building structure; third and fourth tower legs with third and fourth rosette attachment connectors; a second landing beam mounted between the third and fourth tower legs; third and fourth landing beam support connectors for connecting to the third and fourth rosette attachment connectors; and at least one strut member for connecting the first landing beam to the second landing beam.

A multi-level deck system for a blowout preventer and a method, of which the system includes a first deck positioned at least partially around and coupled to the blowout preventer, a second deck positioned at least partially around and coupled to the blowout preventer and vertically spaced apart from the first deck, and a third deck positioned at least partially around the blowout preventer and vertically spaced apart from the second deck.

A support platform for enabling a worker to service an oil well next to a wellhead having a valve tree includes a platform having an upper floor, a lower floor and a cavity in between the floors. A platform provides a periphery, a central opening and radially extending beams. A plurality of walls attached to the periphery of the platform, said beams connecting to said walls below said upper floor. A drain that enables fluid to drain from the upper floor to the lower floor and into the cavity. A coupler that spans between the floors for enabling a connection to be made between the platform and valve tree. A liquid guard or other provision that disallows the escape of fluid from a floor via the central opening. One or more sleeves are provided in the cavity, each connecting to the upper floor, each sleeve having a bore that extends to and through the upper floor. Fluid that drains to the cavity is not able to escape the cavity via the sleeve or sleeve bore.

A scaffolding lift assembly includes a scaffolding and a lift boom that is removably attachable to a respective one of a pair of end frameworks of the scaffolding which is pivotable in a deployed position having the lift boom extending laterally away from the respective end framework. A winch is attached to the lift boom to lift a load of building materials onto the scaffolding. A safety gate is removably attachable to a respective end framework which is biased into a closed position to inhibit a user from inadvertently passing between the pair of end frameworks and falling from the scaffolding. A side gate is removably attachable to the scaffolding and the side gate is slidable into a closed position extending between each of a pair of end sections of the scaffolding to inhibit the user from passing between the pair of end sections and inadvertently falling from the scaffolding.
