To improve the construction of longwall support frames so that an io The rotation of the console relative to the traverse suspension on the line support is possible, without which it can be carried out manually. The respective load is unfavorable and that a transport of the lige position of the console relative to the traverse fixed part longwall construction frames can be carried out largely free of vibrations in order to avoid unnecessary movements of the attached execution. component to be avoided.

The considerable weight of the longwall construction frames, directly or indirectly, with that guided through the traverse is now not only on two running rails arranged next to one another at a lateral distance and connected to one another in this shaft of the console, but rather on. By means of couplings or intermediate gears, which are coupled one behind the other in the direction of travel, the useful slewing speed of the lift truck can also be adjusted to a longer rail length if required. The motor can be electrically, pneumatically divided. As a result, such a transport device can be loaded malically or hydraulically,

This support-transport formation combined support beams can consequently, depending on the type of construction, be evenly lowered with the help of the lifting gear of the longwall frame and the one on the longwall frame or raised, so that the attachment points provided for the expansion frame are adjusted accordingly and no harmful torsional stresses are applied, so that be subjected to a favorable center of gravity suspension.

Device for the hanging transport of longwall frames completely assembled with the help of a device designed in this way, 5 shield frames can be transported in completely assembled two rails suspended from the mounting location on the mountain or on the pit. The disadvantage of this, however, is that the racks, which are coupled to one another at a distance, hang on only one rail, so that they have lifting trucks with lifting gear, thereby swinging out to the side relatively easily and characterized in that the lifting gear (14) 10 track fixtures or other devices or the distance unchangeable Coupled devices in the route, the free cross-section of which are straight lift trucks (11) are attached to the end of a supporting beam in the transition area to the longwall face and in the vicinity of the longwall (16) and two such supporting structures are very tight.

Furthermore, explore the traverse (17) to a transport formation (10), the transport on a running rail allows only small piece weights with part of a piece weight rotatable in the traverse (17) in order to prevent the outsourced person from being arranged below the traverse (17), on which the running rail is usually suspended, th console (22) forming mounting brackets is burdened unfavorably. If the rail is not combined on (23) for an extension frame (4), 20 line extension is suspended, higher pieces are possible, with the traverse (17) having one end (20) in the middle; However, these require a special support beam (16) in one point (18, 19; stiffeners, e.g. in the form of anchors, naturally with 82-84) and with the other end (21) in two in a correspondingly higher Effort are involved. In the longitudinal direction of the other supporting beam (16), the lifting or lowering of the shield supports at the offset points (18, 19; 82-84) must also be carried out with special care, since both the front and the rear of the shield support must be carried out with special care. 2.
