20100218697 | CARRIAGE-TYPE CONVEYANCE DEVICE - The present invention makes it easy to lay-out a carriage traveling path crossing an aisle for a vehicle, etc., in a conveyance device using a carriage which has an object support base movable vertically controlled by cam rails on the floor side, and is characterized in that an automatic lock means for locking an object support base | 09-02-2010 |
20110061562 | CART AND TRACK ARRANGEMENT - A cart and track arrangement includes a track unit having a straight track and a curved track, the straight track having an oblique bearing portion, the curved track having a horizontal bearing portion, and a cart having a cart frame and a wheel set, the wheel set having a wheel axle arranged in parallel to the oblique bearing portion of the straight track and a wheel pivotally mounted on the wheel axle, the wheel having a first tread disposed in parallel to the wheel axle for rotatably supporting on the oblique bearing portion of the straight track and a second tread for rotatably supporting on the horizontal bearing portion of the curved track. In an alternate form, the straight track has a horizontal bearing portion, the curved track has an oblique bearing portion, and the wheel has a first tread disposed in parallel to the wheel axle for rotatably supporting on the horizontal bearing portion of the straight track and a second tread for rotatably supporting on the oblique bearing portion of the curved track. | 03-17-2011 |
20130125780 | GUIDE RAIL TYPE VEHICLE - A guide rail type vehicle is provided with a guide wheel that comes into rolling contact with a guide rail, a switching wheel that is comes into rolling contact with a switching rail installed at a switching location of the guide rail, a wheel axle in which the guide wheel is connected to the top end and the switching wheel is connected to the bottom end, a support receiver of which the height dimension is set to be smaller than the corresponding length dimension of the wheel axle and which supports the wheel axle, and adjustment device which adjusts the sizes of a gap of the guide wheel side and a gap of the switching wheel side, which are accessed from a direction orthogonal to the axial direction of the wheel axle, and are therefore capable of adjusting the height of the guide wheel and the switching wheel. | 05-23-2013 |
20140345490 | SYSTEM FOR MOVING HEAVY OBJECTS ABOUT A REMOTE MANUFACTURING YARD - A system for moving heavy objects about a manufacturing yard is provided. In one embodiment, the system can include a pair of rails disposed on the ground of the manufacturing yard; a plurality of multi-ton rollers configured to mate with the rails, each multi-ton roller configured to be attached to a movable platform which is configured to accept a packed column section; and a winch disposed between the pair of rails and secured to the ground of the manufacturing yard, the winch having a spool of cable with one end configured to be attached to the movable platform, the winch configured to apply a force to cause the movable platform to travel about a length of the pair of rails. | 11-27-2014 |
20150033977 | SERVICE VEHICLE FOR REPLACING IDLERS OF A BELT CONVEYOR - A track displaceable service vehicle replaces individual worn or damaged idlers with new idlers in the upper run and lower run of a belt conveyor with rising or falling conveying route, in which there is little space for the use of the service vehicle for replacing the idlers. The service vehicle accommodates a magazine for new and worn idlers and auxiliary devices for lifting the belt and removing old and for installing new idlers. A platform carries service personnel, and can be brought into a horizontal position in case of an inclined travel route of the service vehicle. The replacing of worn or defective idlers takes place in certain cycles in which the entire segment of the belt conveyor is removed and all worn and defective idlers are replaced. The service vehicle has a drive and is suitable for long tunnel sections (conveying routes which extend over several kilometers). | 02-05-2015 |
20160185367 | APPARATUS AND METHOD FOR LIFTING AND MOVING AN AXLE OF A RAIL VEHICLE - An apparatus for lifting and moving an axle of a rail vehicle includes a frame, a pair of rollers rotatably mounted to the frame to movably support the frame on a railroad track rail, and a pair of wedges mounted to the frame having mutually opposed ramped faces. The pair of wedges adjustable along the frame between a first position in which the ramped faces bracket, but do not contact, a rail vehicle wheel that rests on the track rail, and a second position in which the ramped faces engage the circumference of the wheel to support the wheel at a height above the railroad track rail. The apparatus further includes at least one jacking device for urging the wedges toward one another from the first position to the second position. | 06-30-2016 |
