Reusable, flexible, lightweight, low cost flexible intermediate bulk containers (FIBCs) for the delivery of granular proppant material for fracing that will allow the transport of higher weights of proppant, such as sand, per truck load. The invention includes a container made of a high strength, flexible material with a top opening for loading and deploying the proppant. The container can be lifted and deployed with a fork truck or crane. Alternatively, proprietary deployment systems, such as a conveyor system, can be used to quickly and efficiently deploy the proppant from the container at a desired site.

Computer aided design software for designing a building or other structure of brick construction, where in addition to the usual three dimensional modelling and rendering typical of CAD software, tabular data describing the spatial location and orientation of each brick is provided, including information regarding which bricks are cut to length so as to be shortened, and where they are located along each course, and which bricks are machined, drilled or routed for services or other special fittings. Data pertaining to this is compiled in a database for access by control software to control a brick laying machine to build a building or other structure from bricks. The database may receive via interface with a scanner data being a measure of the elevation of the footings and/or concrete pad that has been constructed according to the building plan and for each brick of the first course, to determine how much material must be machined off the bottom of each brick so that when the first course is laid, the tops of the bricks of the first course are at the same level. This machining data is stored for each brick with the tabular data produced by computer aided design software, so that the control software can control the brick laying machine to machine and cut each brick as per the stored data, and convey each brick to the stored position on the footing, pad or previously laid course of bricks, with application of adhesive prior to positioning of the brick.

An apparatus and method for transporting a plurality of articles is disclosed. The apparatus includes a wheeled chassis, and a platform disposed on the wheeled chassis. The apparatus also includes a manipulator coupled to the wheeled chassis and operably configured to load a first article of the plurality of articles at a first position on the platform, or unload the first article of the plurality of articles from the first position on the platform. The apparatus further includes at least one actuator operably configured to cause successive relative rotational movements between the manipulator and the platform to provide access to successive rotationally spaced apart positions on the platform for loading or unloading each subsequent article in the plurality of articles.

Embodiments of the present invention include a method and system for controlling the flow rate of materials into and out of the blender. The system includes the control and management of an on-site storage system for each component of a mixture, regulating the delivery rate of a blend mixture into a blender hopper, regulating the exit rate of the blended mixture from the blender hopper, and coordinating the flow of materials into and out of the blender.

A hoist mechanism having an improved locking assembly. A hoist mechanism includes a frame including a first end and a second end, and the frame is pivotably coupled with a mounting structure at the frame first end. The hoist mechanism also includes a hoist arm assembly pivotably coupled with the frame second end, and the hoist arm assembly includes a jib operative to move between an extended position and a retracted position. The locking assembly includes a lug disposed on the jib and a link arm coupled with the frame. The link arm defines a slot dimensioned to selectively engage with the lug when the jib is moved from the retracted position. The hoist arm assembly is pivotable with respect to the frame when the jib is in the retracted position, and the frame and the hoist arm assembly are pivotable together when the jib is in the extended position.

A control system is described for a base supporting a telescoping articulated boom assembly indicated generally at 15, comprising long telescopic boom 17 and telescopic stick 19. Mounted to the remote end 21 of the stick 19 is an end effector in the form of a head 23 that supports a 6 axis robot arm 25 that moves a further end effector 27 to manipulate the items. The robot arm 25 has a robot base 31, and mounted above the robot base 31 is a first target in the form of a 6 degree of freedom (6 DOF) high data rate position sensor 33, that provides 6 DOF position coordinates, relative to a fixed ground reference 35, to a control system. Mounted on the end of the robot arm 25 immediately above the end effector 27 is a second target in the form of a 6 degree of freedom (6 DOF) high data rate position sensor 37, that provides 6 DOF position coordinates, relative to the fixed ground reference 35, to the control system. The fixed ground reference 35 tracks the sensor 33 and feeds data to the control system to move the head with slow dynamic response within range of work for the robot arm, and tracks the sensor 37 to control movement of the robotic arm 25 and end effector 27 with fast dynamic response.

A device for movably mounting a storage container in relation to the storage bed of a pickup truck. The device includes a container support frame with a mounting member configured to be fixedly secured in relation to the pickup truck storage bed, and a lift arm having a first end coupled to the container support frame for pivotal movement about a first pivot axis and a second end configured to be coupled to the storage container for pivotal movement about a second pivot axis. The second end of the lift arm is movable along an arcuate path about the first pivot axis between a stowed position in which the storage container is disposed between the side rails and an extended position in which the storage container is disposed above a side rail. The storage container is pivotable about the second pivot axis to maintain an upright orientation in the stowed and extended positions, providing a variety of convenient access and storage options. Also, the frame can be confined to a very small portion of the storage bed or hidden within existing components of the storage bed to allow substantially unimpeded top and rear access to the storage bed.

Mainframes for a self-propelled machine are disclosed. The mainframe includes first and second pockets that extend from the front end to the rear end of the mainframe. A hydraulic reservoir housing extends from the first side to the second side of the mainframe. The hydraulic reservoir housing is disposed between the front end of the mainframe and first and second drive openings.
