摘要： A device is mounted to the end of a log so that a skid steer may use the log to engage a tree targeted for felling. The device includes implements configured for engaging the target tree to be felled to give the operator of the device control over the target tree. The device is structured to push the target tree over such that the root ball of the target tree rises up out of the ground as the target tree is felled and/or to allow the operator to make cuts to the target tree before the device is use to push the tree in the desired direction of fell.

摘要： A tractor trailer jacking assembly f includes a plurality of jacks that is each mounted on a bottom of a tractor trailer. Each of the jacks is positionable in an extended position to engage the ground to inhibit the tractor trailer from tipping. A control circuit is mounted on a semi tractor and the control circuit detects the speed of the semi tractor. A gyroscope unit is mounted on the semi tractor to detect a degree and a direction to which the semi tractor is tipping. The control circuit actuates the respective jacks into the deployed position on a corresponding side of the tractor trailer when the gyroscope unit detects the semi tractor has tipped beyond a pre-determined angle of tilt.

摘要： An apparatus includes a housing, a piston, an input cavity, a first actuating shaft, a first output cavity, and a second output cavity. The housing comprises an input port, a first output port, a second output port, a first end, a second end, a first wide wall having a first internal surface, and a chamber at least partially defined by the first end and the first internal surface. The piston is able to actuate along the first internal surface of the first side wall. The input cavity is in fluid communication with the input port. The first output cavity is in fluid communication with the first output port. The second output cavity is in fluid communication with the second output port. The first actuating shaft is fixed to the piston and helps fluidly isolate the first output port from the second output port.
