A working machine may include a battery box and a battery detachably attached to the battery box. The battery box may include a top cover, and a battery cover having a shape that covers the battery attached to the battery box and being pivotable about a pivot axis with respect to the top cover. When the battery box is viewed in a top plan view in an open state in which the battery cover is open, the battery cover and the top cover may at least partially overlap with each other. When the battery box is viewed in the top plan view in a closed state in which the battery cover is closed, the battery cover and the top cover may at least partially overlap with each other.

A dolly includes a frame having an axle extending between dolly wheels and defining a pivot axis. The frame has a support member with a ground-engaging element spaced apart from the dolly wheels. A lever arm is mounted to the frame and extends to a handle. The lever arm is positioned on a first side of the axle. A container support is mounted to the frame on the first side of the axle. The handle is manipulable to pivot the support member, the lever arm, and the container support about the pivot axis between at least a storage position and a discharge position. In the storage position, the container axis has an upright orientation and the ground-engaging element is spaced from the ground surface. In the discharge position, the container axis has an orientation being substantially parallel to the ground surface, and the ground-engaging element abuts against the ground surface.

A tool can aid in articulating a water heater onto, and off of, an elevated pedestal. The tool can consist of at least a frame that is pivotally attached to a stationary base via a fulcrum feature. The frame may be sized to support a water heater with at least a pair of rails. The stationary base can have at least one rigid pivot stop cantilevered from a base body and shaped to maintain the stationary base at a non-normal tilted orientation.

A trolley for collecting waste includes: wheels, a steering handle, and a housing with a bottomwall and a sidewall extending vertically from the bottomwall, wherein the housing forms a waste chamber, wherein the sidewall comprises an opening, wherein a flap is connected by a first bearing to the sidewall of the housing, such that the flap is pivotable about a horizontal flap axis between a closing position and an opening position. The flap in its closing position closes the opening of the sidewall, and the flap in its opening position opens the opening in the sidewall, wherein the handle is connected by a second bearing to the housing, such that the handle is pivotable about a handle axis between a first handle position and a second handle position, and the handle is linked to the flap by a mechanical linkage, such that pivoting the handle from its second handle position to its first handle position results in a pivoting of the flap from its opening position to its closing position.

A device for spraying a liquid for use in dye penetration inspection into an inner cavity of a workpiece for making a turbine engine part, the device including a workpiece support, a manifold for spraying the inspection liquid into the inner cavity, a manifold for sucking up and discharging the sprayed inspection liquid, and a mechanism for tilting at least a portion of the support from a substantially horizontal position to an inclined position in which the workpiece is inclined so that the inspection liquid sprayed into the cavity flows under gravity to a zone from which it is sucked up.

A collapsible cart having a frame that extends from a handle to an opposing wheel housing is provided. The wheel housing may provide a plurality of wheel, each wheel independently movable between a folded condition nested therein and an extended condition operably protruding from the wheel housing so that a user manipulating the handle steers the collapsible cart along a supporting surface. A plurality of collapsible brackets and crates may be provided along the frame so as to be movable between an operable configuration for transporting objects and a collapsed configuration for storage of the collapsible cart.

A wheeled shoveling device which allows the user to scoop up snow, lift the load using the natural weight of the user as a counter-balance, and transport the load to a location whereby it can be frontally discharged using a hand-powered pulling motion on an attached jointed lever. The scoop is attached using a bushing-style hinge, to a large inverted A-shaped frame, allowing the scoop to pivot forward after application of the jointed lever, effectively discharging the scoop. The inverted “A” frame has an axle and pair of wheels which act as both a fulcrum, as well as a means for transporting the load to another location with the load being held above the ground. The scoop has a pair of small protruding wheels attached to the sides of the scoop box, preventing the scoop's leading edge blade from jamming against terrestrial surface imperfections.
