| 20100329773 | ELEMENT FOR CONNECTING A LATTICE SYSTEM - An element is provided for connecting the chords of a lattice system, which consists of upper chords and lower chords, between which struts and/or stays are arranged, to a telescopic boom head. Thereby, the lower chords are directly connected to the telescopic boom head by means of bolts, while the upper chords can be connected to the telescopic boom head by a connecting element of variable length in such a way that—with respect to the connection of the lower chords—the upper chords can be connected to one another at a variable angle, and wherein the connecting element consists of two butt straps which can each be fastened at one end of mutually facing ends of the upper chords and can be connected to one another at different points. | 12-30-2010 |
| 20100320166 | CRANE, IN PARTICULAR MOBILE CRANE WITH A NARROW TRACK AND ENLARGED SUPPORTING BASE - A mobile crane includes an undercarriage with a middle section and two parallel crawler carriages; a superstructure on which a boom is mounted, the superstructure being connected to the undercarriage by a rotary joint; two longitudinal outriggers connected to the undercarriage and extending in the longitudinal direction between the crawler carriages; and two transverse outriggers connected to the undercarriage and extending outside the crawler carriages. One of the longitudinal outriggers has an end with a transverse beam supported by spaced apart outrigger cylinders which provide an extended tipping edge to further stabilize the crane. | 12-23-2010 |
| 20100319337 | HYDROSTATIC DRIVE SYSTEM - The invention relates to a hydrostatic drive system having a pump ( | 12-23-2010 |
| 20100313555 | Hydraulic Control Circuit For Overcontrol Of A Slewing Gear Drive - A hydraulic control circuit for the overcontrol of a hydraulic system which controls a drive, in particular for controlling a hydraulic motor ( | 12-16-2010 |
| 20100294738 | ANGLE ADJUSTMENT OF A JIB SYSTEM - Method for adjusting the angle of a jib system of a crane, comprising the steps of providing two jib units of the jib system, which can be variably arranged with respect to their longitudinal axes in an angle position in relation to one another, arranging connecting links attached to the jib units in such a way that the longitudinal axes of the jib units are parallel in a starting angle position, starting openings and target openings of the connecting links are aligned with one another pairwise to insert a connecting element connecting the jib units, the aligned starting openings being connected with the connecting element, relieving the connecting element connecting the aligned starting openings, removing the first connecting element, connecting a pair of the aligned target openings with the connecting element, and arranging the jib units in a target angle position which is different from the starting angle position. | 11-25-2010 |
| 20100252522 | Auxiliary Device For Installing The Lower And Upper Jib Support Of An Adjustable Auxiliary Boom On A Mobile Crane - An auxiliary device for equipping the main boom of a mobile crane with an auxiliary boom, wherein a support is mounted near the head of the main boom, by means of which the lifting cable of the main boom may be run to a connection point on the auxiliary boom. The invention further relates to a method for equipping with an auxiliary boom. | 10-07-2010 |
| 20100213154 | LOCKING AND BOLTING UNIT - A locking and bolting unit for sections telescoping out of a basic element, in particular sections of a telescoping boom of a mobile crane. The invention involves a locking and bolting unit for sections telescoping out of a basic element, in particular sections of a telescoping boom of a mobile crane, comprising two safety bolts ( | 08-26-2010 |
| 20100193458 | Controller for an Adjustable Jib Extension of a Mobile Crane - The invention relates to a controller for an adjustable jib extension of a mobile crane, comprising a telescoping main jib and a jib extension placed thereon, the luffing angle of the extension being adjustable by way of a luffing winch or a piston-cylinder unit. For this purpose, the actuation of the winch moving the luffer or of the piston-cylinder unit is carried out via a control circuit such that during the extension and/or retraction of the telescoping jib, or when changing the angle of the main jib with respect to the horizontal, the angle of the luffer with respect to the telescoping main jib and/or the horizontal remains constant or changes to a predefined extent. | 08-05-2010 |
| 20100051570 | Vehicle Crane with a Bogie and a Superstructure - The vehicle crane comprises a truck carrier and a superstructure in which the driving of the superstructure function is carried out by means of hydraulic pumps in the truck carrier, and the hydraulic pumps are driven by a distributor gear unit which is arranged in the truck carrier and to which the output shaft of the vehicle drive is connected. | 03-04-2010 |
| 20100038333 | Telescopic Crane Boom - A telescopic crane boom including a plurality of telescopically assembled tubular box sections including a base box section and an innermost box section having an open cross-section, and a boom head with a frame fixed to the outside circumference of the innermost box section. The head has a plurality of deflecting pulleys mounted on the frame, but no part extending inside the open cross section on the innermost base box section, whereby at least one additional box section can be inserted into the innermost box section in order to extend the boom. | 02-18-2010 |
| 20090133954 | Rear axle steering system for a mobile crane - A rear axle steering system for a mobile crane including at least one actively steered rear axle with wheels arranged thereon. A rear axle steering system of this type is provided with a hydraulic steering system including one or more hydraulic steering cylinders of which a particular number are in each case associated with an actively steered rear axle in order to steer this actively steered rear axle in a desired manner. A braking system is adapted to individually brake each wheel of the at least one actively steered rear axle. In the event of an error in the hydraulic steering system, a control system actuates the braking system in such a way that by selective braking of at least one wheel of the actively steered rear axle, which is affected by this error, the rear axle is brought to a predetermined, desired steering position. A method of steering a rear axle, with wheels of a mobile crane arranged thereon, by means of a hydraulic steering system. | 05-28-2009 |
