20150008381 | ROPE WINCH - The present invention relates to a hoisting winch, in particular to a hoisting gear winch, having a hoisting drum whose winding region is bounded by two lateral flanged wheels, wherein at least one further flanged wheel is provided between the lateral flanged wheels for dividing the winding region into at least two part winding regions, wherein the cable can be guided beyond the named further flanged wheel into the at least two part winding regions. It is suggested in accordance with the invention to move the hoisting drum and/or a transverse cable guide arranged in front of the hoisting drum transversely to the longitudinal direction of the running in/running off cable approximately in the longitudinal direction of the drum and/or to adjust the angular position of the hoisting drum transversely to the longitudinal direction of the drum with respect to at least one transverse axis. | 01-08-2015 |
20140213404 | POWER SPLIT TRANSMISSION - A power split transmission, in particular for a traction drive, having at least one drive shaft and at least one output shaft between which a mechanical first branch and a hydraulic or electrical second branch are provided that can be connected to one another at least in part by a planetary gear arrangement, wherein the second branch comprises a plurality of energy converters. The at least one drive shaft can be connected to a first energy converter and to a first connection element of the planetary gear arrangement, while the at least one output shaft can be connected to a second connection element of the planetary gear arrangement and the second and third energy converters can be connected to at least one or more further connection elements of the planetary gear arrangement and/or of the at least one output shaft. | 07-31-2014 |
20140109682 | Rope Test Stand - A cable test bench for testing a test cable to establish service life, replacement age, number of flex cycles, and/or winding behavior, has a deflection system including at least one deflector roll to deflect the test cable, one test cable drive to wind and unwind the test cable via the deflection system, and one test load to load the test cable. The cable test stand has an additional cable test drive for winding and unwinding a safety cable and/or the named test cable, and a control device for controlling the additional cable drive and/or the test cable drive in a manner wherein the two are adjusted to each other, in such a manner that the load of the test cable can be adjusted differently for different test cable segments and/or different winding directions and/or different winding cycles and/or different phases of a winding cycle. | 04-24-2014 |
20140027691 | HOIST DRUM AND ROPE PULLEY FOR FIBER ROPE DRIVES - The present invention relates generally to rope drives working with high-strength fiber ropes such as crane hoists, boom adjustment gear, trolley traveling gear. etc. The invention in this respect in particular applies to hoist drums for the rope hoist winch of such a fiber rope drive having a drum jacket body which is provided with grooving at the peripheral side and having two guard plates adjacent to the drum jacket body at the end sides. The invention further relates to a rope pulley for such a fiber rope drive having a rotatably supported pulley body whose jacket surface has at least one rope groove. In accordance with the invention, the rope grooves have a flat-pressed, round groove contour which differs from the circular and which has a larger radius of curvature in the region of the groove base than in the region of the groove flanks adjacent thereto. | 01-30-2014 |
20140027401 | APPARATUS FOR RECOGNIZING THE DISCARD STATE OF A HIGH-STRENGTH FIBER ROPE IN USE IN LIFTING GEAR - The present invention relates generally to lifting gear such as cranes which use high-strength fiber ropes instead of steel ropes. In this respect, the invention in particular relates to an apparatus for recognizing the discard state of a high-strength fiber rope in use at such lifting gear comprising a detection device for detecting at least one rope parameter as well as comprising an evaluation unit for evaluating the rope parameter and for providing a discard signal in dependence on the rope parameter evaluation. In accordance with the invention, the detection device of the apparatus for recognizing the discard state comprises a plurality of differently configured detection means for a magnetic, mechanical, optical and/or electronic detection of a plurality of different rope parameters which can be evaluated by the evaluation unit individually and/or in combination with one another for recognizing the discard state. | 01-30-2014 |
20130112931 | WINCH - The present invention relates to a winch, in particular a luffing winch, with a winch drum, at least one main drive driving the transmission input shaft, and at least one emergency drive driving the transmission input shaft in case of emergency, wherein at least one emergency drive can be coupled to the driven wheel of the transmission input shaft as required via at least one intermediate gear. The present invention furthermore is directed to a construction machine or a lifting device with at least one such winch. | 05-09-2013 |
20130038114 | SELF-PROPELLED SURFACE MILLING CUTTER - The present disclosure relates to a self-propelled surface milling cutter, with a working assembly comprising a rotatingly drivable drum body, and at least one drum drive unit which is accommodated in the interior of the drum body and forms at least part of a rotatable bearing of the drum body on a drum supporting frame, wherein the at least one drum drive unit includes a stationary drive part attached to the drum supporting frame and a rotatable drive part connected with the drum body. The rotatable drive part of the drum drive unit is mounted on the drum body by a positive entrainment connection in a torque-transmitting, but longitudinally movable manner. The entrainment connection rotatorily entrains the drum body, in order to be able to transmit the rotary drive movements of the drive part to the drum body. | 02-14-2013 |
