A support jack, in particular for supporting semitrailers, includes a vertically telescopically displaceable supporting element having an outer sleeve, and an inner sleeve that can be vertically displaced in a telescopic fashion, each sleeve having a rectangular cross-section with four sidewalls. At least the inner sleeve has a wall plate joined to two adjacent side walls with welding seams that improve the bending stiffness of the support jack. The welding seams can be located inside or outside either of the sleeves. Such a support jack can be located on the lower side of any vehicle.

The invention describes an arrangement of lubricating grease inside the housing of a gear unit with rotatable components, particularly the gear unit of a jack. It also describes a grease pouch for receiving lubricating grease and a method for lubricating the gear unit with lubricating grease. Since the gear units are often not transported in their installed position, oil that has separated from the lubricating grease may leak from any gearbox openings. Thus, one of the objects of the invention was to provide an arrangement of lubricating grease in the housing of a gear unit, which on the one hand provides lubrication of the gear unit so that it is ready for operation in its delivery condition and on the other hand effectively prevents the oil separated from the lubricating grease from leaking prior to initial startup. This object is attained by enclosing the lubricating grease within at least one grease pouch prior to initial startup of the gear unit. The at least one grease pouch is inserted into the housing of the gear unit so as to contact the components. Upon initial startup the at least one grease pouch is torn open by the action of the components and releases the lubricating grease.

A landing gear assembly for a semitrailer includes a pair of legs that may be simultaneously raised or lowered by turning a single crank. Each of the legs is configured to be able to be mounted in either an inboard or outboard configuration. This is achieved by providing both sides of each leg with no protrusions that extend beyond the space provided in the mounting bracket and the mounting hole used to connect the landing gear to the semitrailer. The gear assembly of the landing gear includes a unique floor base that receives and supports the input shaft. A cover is used to support the input ends of the input shaft and the output shaft. The cover is connected to the input side of the upper tube of the leg and allows the gear assembly to be easily assembled within the perimeter of the upper leg.

A semi-trailer landing gear, in particular to support trailers, with a support element which includes an outer sleeve and an inner sleeve and which can be displaced in a telescopic manner in relation to the height. The outer sleeve includes a securing flange which can be applied to a vehicle. The aim of the invention is to develop a semi-trailer landing gear which is economical to produce and can also withstand high loads. The aim is achieved by virtue of the fact that the outer sleeve and the securing flange are made of a single piece of flat steel by edge rolling.

A support jack for supporting semitrailers including a vertically telescopically displaceable supporting device having an outer sleeve and an inner sleeve. A spindle nut has projections and contact elements for being positively detachably connected to the sleeves. The projections interact with openings of the inner sleeve for fixing the spindle nut in the direction of the longitudinal axis of the support jack. The contact elements interact with an inner side of the outer sleeve for fixing the spindle nut in the direction of rotation about the longitudinal axis. A method of assembling a support jack is also described, in which the spindle nut is connected detachably to the inner sleeve by at least one translatory and one rotary joining movement or at least two translatory joining movements.

An actuator or servo device comprises an actuator member adapted to move linearly in the motion space of an actuator housing, a microwave position detecting device for detecting the position of the actuator member in the motion space, the actuator member being capable of producing a pressure wave acting on the position detecting device on approaching the position detecting device and a high frequency microwave antenna arrangement for emitting and receiving microwaves, which are at least partially reflected by the actuator member. The actuator device includes dielectric guard cover means, arranged in front of the microwave antenna arrangement. For mechanically uncoupling the guard cover means from the microwave antenna arrangement between the guard cover means and the microwave antenna arrangement a clearance is maintained to allow deformation of the guard cover means thereinto owing to pressure waves.

An attachment element (12) for the selective pivotal and/or fixed bearing of a power cylinder, comprising a base region (33) having attachment means (45) for its attachment on a support structure (35) and from which two attachment arms (32) extend opposite each other with a distance between them, the attachment arms (32) being provided with bearing means (29) for a pivotal bearing engagement on oppositely placed sides of the outer periphery of the power cylinder (10). The base section (33) is designed with bearing means (41) for any additional terminal interlocking bearing engagement with the power cylinder (10) as may be required. Furthermore a cylinder end cap is proposed matching the attachment element (12).
