A patient support apparatus for traversing objects supported on ground surfaces. The patient support apparatus comprises a patient support deck, and a base to support the patient support deck from the ground surface. At pair of caster wheel assemblies spaced from each other are coupled to the base for pivoting movement about respective pivot axes cooperating to define a reference plane. A frame guard coupled to the base defines first and second ramp surfaces each disposed at an angle relative to the reference plane. The first ramp surface is arranged to engage objects before they contact one or more of the caster wheels when the patient support apparatus moves in a first direction. The second ramp surface is arranged to engage objects before they contact one or more of the caster wheels when the patient support apparatus moves in an opposite, second direction.

Disclosed a dual-function electric stair-climbing vehicle. A bicycle-like saddle is mounted at an upper part of a frame of the vehicle; and a worm gear reducer is mounted at a middle part of the vehicle for driving two rotating legs to climb up or downstairs. The vehicle is mainly used for fire rescue in high-rise buildings, equipment maintenance of high-rise buildings when no elevator is available, and fast transportation of equipment, materials and firefighters or maintenance men upstairs. When the width of a corridor is greater than 1.1 m, the vehicle can be rode upstairs directly with people and goods; when the width is less than 1.1 m and greater than 0.9 m, people need to get off and make a turn; and when the width is less than 0.9 m, the vehicle is not available. The dimension of the frame is about 1200×550×380 mm.

The present disclosure discloses a multi-stage load adjustment type moving cart. The multi-stage load adjustment type moving cart according to the present disclosure includes: a base frame; a vertical frame vertically installed on one side of the base frame; an inclination angle adjustment unit installed on one side of the vertical frame and configured to selectively elongate a rod; a variable inclination rail having an upper one end supported to be rotatable around a hinge point hinge-coupled to the vertical frame and having one lower end connected to the inclination angle adjustment unit; and a raising and lowering unit including a raising and lowering body provided with a first roller and a second roller coming into rolling.

A sewer cleaning machine includes a frame and a drum rotatably supported by the frame. The drum is positioned on a first side of the frame. The sewer cleaning machine also includes a first motor supported by the frame and coupled to the drum. The first motor is operable to rotate the drum. The sewer cleaning machine further includes a cable positioned at least partially within the drum. The cable is configured to be extended from and retracted into the drum. The sewer cleaning machine also includes a track positioned on a second side of the frame. The track includes a first endless belt configured to rotate about a first roller. The sewer cleaning machine further includes a second motor supported by the frame and coupled to the first roller. The second motor is operable to drive the track.

A rollable hamper assembly for transport of laundry and laundering supplies includes a housing having walls coupled thereto and positioned therein to define a chamber and a plurality of compartments. The chamber and compartments are used to stow articles and are accessible from an upper and rear face of the housing, respectively, which are open. An upper lid selectively closes the upper face of the housing. A pair of first rods is engaged singly to opposed sides of the housing, proximate to the rear face. The first rod comprises a plurality of nested sections and is selectively extensible. A second rod is coupled to and extends between the first rods distal from the housing. The second rod can be utilized by a user to motivate the housing upon rolling wheels, which are engaged to a bottom of the housing. The second rod can be used for hanging items.

A utility cart including a rectangular base is provided. The utility cart includes at least one handle extending outward and upwards from a short side of the rectangular base and a leg extending down from the short side of the rectangular base on the short side of the handles. The utility cart also includes a first wheel assembly joined to the rectangular base on end opposite to the handles, wherein two wheels and the leg are positioned such that the rectangular base is horizontal with a floor, two holes centered along each long side of the rectangular base, and a first adjustable guard that fits into the two holes.

A hand truck having a frame with first and second ends and a handle adjacent the first end and a platform extending from the second end. Wheels adjacent the second end support the frame and platform for rolling movement. A lever member with first end pivotally connected to the frame at the first end and second free end. A position stabilizing member is pivotally connected to each side of the frame proximate the second end with each shoe assembly being pivotal to a support position extending below a respective wheel. The free end of the lever member is positioned against a surface and the frame pivoted thereabout with the shoe portion of each shoe assembly moving to the support position. An automatic braking system prevents unwanted downward movement. A repositioned lever member and multiple commonly hinged lever members allow for full stair lifting and elimination of the position stabilizing member.

The disclosure relates to a transport device, in particular for transporting luggage, which comprises a support structure, a coupling element or a handle and a rolling body in addition to a transport container for receiving objects, in particular luggage. The rolling body has a rotational symmetry and is configured such that it tapers in diameter towards the ends along the axis of symmetry. Because of the arrangement and design of the transport container, the transport device is self-stabilizing in operative use.

A traveling direction state detection device includes: a first distance sensor installed near a front side of the wheels in a traveling direction and configured to linearly measure a distance to a first linear position perpendicular to the traveling direction, the first linear position existing on the traveling surface diagonally downward in the traveling direction; a second distance sensor configured to linearly measure a distance to a second linear position perpendicular to the traveling direction, the second linear position existing on a traveling surface behind the traveling surface diagonally downward in the traveling direction, and ahead of ground contact points of the wheels; and a detector configured to detect a step, an inclination and an opening of the traveling surface based on an amount of change in the distances continuously measured by each of the first distance sensor and the second distance sensor at certain time intervals.

The present disclosure discloses a multi-stage load adjustment type moving cart. The multi-stage load adjustment type moving cart according to the present disclosure includes: a base frame; a vertical frame vertically installed on one side of the base frame; an inclination angle adjustment unit installed on one side of the vertical frame and configured to selectively elongate a rod; a variable inclination rail having an upper one end supported to be rotatable around a hinge point hinge-coupled to the vertical frame and having one lower end connected to the inclination angle adjustment unit; and a raising and lowering unit including a raising and lowering body provided with a first roller and a second roller coming into rolling.
