20090184492 | ROLLOVER LIMITING VEHICLE COUPLING APPARATUS - The present invention provides a rollover limiting vehicle coupling apparatus for coupling two vehicles, wherein apparatus is configured to provide stability in certain directions in one mode of operation, and is further configured to prevent transmission of rollover between vehicles in another mode of operation. | 07-23-2009 |
20090185886 | SELF-LEVELLING MECHANICAL SYSTEM FOR A MATERIAL HANDLING DEVICE - The present invention provides a material handling device comprising: a support trailer configured for movement thereof; a material holding device pivotally connected to the support trailer, the material holding device configured for reversible rotational movement between a first lowered orientation and a second elevated orientation; an accessory support pivotally connected to the material holding device, wherein the accessory support is coupled to the material holding device at a location wherein the accessory support translates when the material holding device is reversably moved between the first lowered orientation and the second elevated orientation; and a linkage system operatively interconnecting the support trailer, the material holding device and the accessory support, wherein the linkage system is configured to substantially maintain a desired orientation of the accessory support during reversible rotational movement of the material holding device. | 07-23-2009 |
20090191034 | REMOTE CONTROLLABLE MATERIAL HANDLING SYSTEM - The remote controllable material handling system comprises a material handling device configured to carry particulate matter, which includes one or more operatively coupled actuators, wherein the actuators are configured to transfer the particulate matter carried by the material handling device and are responsive to one or more control signals. The remote controllable material handling system further includes a MHD receiver operatively connected to the material handling device, which is configured to generate the one or more control signals in response to one or more transmission signals originating from a wireless remote transmitter. The wireless remote transmitter is moveable relative to the material handling device, and configured to receive as input one or more operator instructions for generating the one or more transmission signals for transmission to the MHD receiver in response to the one or more operator instructions. | 07-30-2009 |
