Description

The invention relates to a driver's workstation unit for a push mast stacker, wherein the driver's workstation unit contains a driver's workstation.In push mast stackers, a structure is usually provided with a vehicle chassis and a driver's workstation unit which can be mounted and fastened as a separate unit on the vehicle chassis. The vehicle chassis comprises a vehicle frame, a drive wheel, load rollers arranged on wheel arms, a traction drive, a steering drive, a hydraulic system, a brake system and a traction battery. On the vehicle chassis, a lifting mast is also arranged on the wheel arms so as to be displaceable in the longitudinal direction of the vehicle. The vehicle chassis thus has the essential technical components of the push mast stacker and is also referred to as a rolling chassis.The driver's workstation unit, which forms a separate unit and within which the driver's workstation is arranged, is provided with the essential operating elements, for example steering wheel, pedal unit, operating elements, driver's seat, storage compartments. Another function of the driver's workstation unit is to protect the driver located in the driver's workstation unit, for example, from falling objects or from falling shelves. The driver's workstation unit is provided with a driver's protective roof vertically at the top for this protective function. The operator workstation unit provided with the driver's protective roof is arranged and fastened on the vehicle chassis and is also referred to as a so-called top chassis.In known push-mast stackers, the combination of the driver's workstation unit and the driver's protective roof consists of sheet metal elements welded to one another, for example bent sheet metal parts or pressed parts, which simultaneously form corresponding cladding elements, such as a right side wall, a left side wall, a front wall and a rear wall, of the driver's workstation unit, and to which vertical struts are welded, which support the driver's protective roof and to which the driver's protective roof is fastened.A push mast stacker, which is composed of a vehicle chassis and a driver's workstation unit forming a separate unit, is known from DE 10 2005 012 879 A1.In push mast stackers, the combination consisting of the driver's workstation unit and the driver's protective roof has a great variance. Due to different requirements for mark differentiation, as well as special customer requirements, in known driver's workstation units which are produced from sheet metal elements welded to one another, which simultaneously form cladding elements, such as a right side wall, a left side wall, a front wall and a rear wall, of the driver's workstation unit, often some sheet metal blanks of individual sheet metal elements of the driver's workstation unit, which form corresponding cladding elements, are designed differently, so that a plurality of variants of the complete driver's workstation unit must be formed and produced. In addition, the manufacturing costs of the sheet metal elements which simultaneously form cladding elements are high, since the rigidity requirements and strength requirements of the driver's workstation unit can only be achieved via corresponding thick sheet metal thicknesses of the sheet metal elements and / or at the same time complicated stamping geometries of the sheet metal elements, as a result of which high material costs and high manufacturing costs of the driver's workstation unit are caused. Furthermore, the high variance of the driver's workstation units in known driver's workstation units which are produced from sheet metal elements welded to one another, which simultaneously form cladding elements, such as a right side wall, a left side wall, a front wall and a rear wall, which form the driver's workstation unit, results in high investment costs and also equipment and adjustment costs during production.The object of the present invention is to provide a driver's workstation unit of the type mentioned at the beginning which is improved with regard to the disadvantages mentioned.This object is achieved according to the invention in that the operator workstation unit has a load-bearing strut construction which comprises a left load-bearing strut element and a right load-bearing strut element and at least one load-bearing transverse connection element connecting the left strut element and the right strut element, wherein at least one non-load-bearing cladding element is detachably fastened to the load-bearing strut construction.A supporting strut construction or supporting strut element or supporting transverse connection element in the sense of the invention is considered in particular to be a strut construction or a strut element or a transverse connection element which meets all rigidity requirements, stability requirements and strength requirements of the operator's workstation unit.The operator workstation unit according to the invention, together with the supporting strut construction and the cladding elements detachably fastened to the strut construction, has a modular construction which makes it possible in a simple manner to produce a high variance of operator workstation units.According to the invention, the operator workstation unit is thus made from a supporting strut construction which can be produced easily and cost-effectively, for example a tubular construction or profiled construction, which can be fastened to the vehicle chassis. The support strut construction comprises a left support strut element and a right support strut element and at least one transverse support link element connecting the left strut element and the right strut element. The load-bearing strut construction thus represents a type of "skeleton" and meets all requirements for rigidity, stability and strength of the driver's workstation unit. Any required increases in stability, which arise, for example, from corresponding customer requirements, can be adapted favorably on the supporting strut construction in a simple manner by thicker wall thicknesses of the strut profiles, for example, tubular profiles, if required. At least one non-supporting cladding element is detachably fastened to this supporting strut construction. The non-load-bearing cladding elements therefore do not have to absorb and transmit forces required for the rigidity, stability and strength of the driver's workstation unit, so that the non-load-bearing cladding elements can be produced correspondingly cost-effectively and can be varied in a simple manner. The non-supporting cladding elements representing corresponding add-on parts can be embodied in a simple manner differently in the invention, for example with regard to the blank and / or the shape and / or the color, whereby a functional and / or optical differentiation can be achieved in a simple manner. In addition, the requirements for the non-load-bearing cladding elements representing corresponding add-on parts are predominantly of optical nature, since the mechanical requirements with regard to rigidity, stability and strength of the driver's workstation unit are already completely fulfilled by the load-bearing strut construction. This opens up possibilities for producing the cladding elements cost-effectively from thinner sheet thicknesses or from alternative materials, for example plastic. This results in clearly more possibilities from the customer's point of view for achieving an optical, but also functional, distinction. With the invention, a large variance of the driver's workstation unit can thus be provided in a simple and cost-effective manner.According to a preferred embodiment of the invention, the supporting strut construction is provided with a fastening interface, by means of which the driver's workstation unit can be detachably fastened to a vehicle chassis of the push mast stacker. The operator workstation unit formed by the supporting strut construction can thereby be fastened and mounted in a simple manner on the vehicle chassis of the push mast stacker.According to a preferred embodiment of the invention, the cladding element is designed as a left side wall and / or as a right side wall and / or as a rear wall of the driver's workstation unit. The left side wall delimits the driver's workstation preferably to the left side of the vehicle. The right side wall delimits the driver's workstation preferably to the right side of the vehicle. The rear wall delimits the driver's workstation preferably to the rear side of the push mast stacker, in which an entry opening is furthermore formed, which allows the driver to enter and exit the driver's workstation.According to a preferred embodiment of the invention, the cross-connecting element is designed as a front wall. With a transverse connecting element designed as a front wall, which connects and braces the left strut element to the right strut element, a high stability of the supporting strut construction can be achieved in a simple manner.According to a preferred embodiment of the invention, the cross connection element is designed as a front cross strut and / or as a rear cross strut. With a transverse connecting element designed as a front cross-brace, which connects and braces the left strut element to the right strut element, a high stability of the supporting strut construction can be achieved in a simple manner. With a transverse connecting element designed as a rear cross-brace, which connects and braces the left-hand brace element to the right-hand brace element, a high stability of the supporting brace construction can be achieved in a simple manner. Furthermore, by appropriate design of the rear cross-member, an ergonomically favorable entry opening can be provided in a simple manner, which enables the driver to enter and exit the driver's workstation ergonomically.According to a preferred embodiment of the invention, the cladding element is detachably fastened to the supporting strut construction by means of at least one screw connection and / or by means of at least one clip connection and / or by means of at least one hook connection. In particular, a combination of a plurality of these connection types is also conceivable. For example, a cladding element with a hook connection and a screw connection can be detachably fastened to the supporting strut construction, whereby a simple and quick assembly of the cladding element can be achieved. For this purpose, the load-bearing supporting strut construction is provided, for example, with rivet nuts or receiving bores for fastening screws at various points as an interface for the cladding elements to be attached.According to a preferred embodiment of the invention, the supporting strut construction is provided with attachment interfaces to which at least one of the following components is attached:• Driver's seat• Steering operator control unit, in particular a steering wheel• Arm rest, in particular an armrest• Floor plate, in particular a floor plate with at least one pedal• Operator control elements, in particular at least one operator control lever• Display element, in particular a display• Electronics holderAs a result, the components mentioned can be arranged and fastened to the supporting strut construction in a simple manner.According to a preferred embodiment of the invention, the supporting strut construction is provided with the guard roof.The driver's protective roof can be rigidly connected to the supporting strut construction, for example by welding.According to a preferred embodiment of the invention, the left strut element and the right strut element are each provided in the vertically upper region with a fastening interface, by means of which the driver's protective roof is detachably fastened to the strut elements. This makes it possible in a simple manner to fasten different variants of driver's roofs, for example a strut roof with metal struts or a glass roof, to the supporting strut construction, so that it is also possible in a simple manner to provide a variance of the driver's workstation unit with respect to different designs of the driver's roofs.According to a preferred embodiment of the invention, the left-hand load-bearing strut element and the right-hand load-bearing strut element each comprise a front vertical strut and a rear vertical strut, which are connected to one another by means of at least one longitudinal strut. The left-hand load-bearing strut element and the right-hand load-bearing strut element thus represent a ladder-like or truss-like strut construction which can be produced in a simple manner in such a way that the mechanical requirements for rigidity, stability and strength of the operator's workstation unit are fulfilled.According to a preferred embodiment of the invention, the front vertical strut and the rear vertical strut of the right strut element and of the left strut element are connected to one another in the vertically upper region by means of an upper longitudinal strut, wherein the upper longitudinal strut is provided with the fastening interface by means of which the driver's protective roof is detachably fastened to the strut elements. This achieves a simple construction of the two strut elements from a few components, since the vertical struts are raised vertically upward in such a way that the fastening interface can be formed on the upper longitudinal strut, to which the driver's protective roof is detachably fastened on the strut elements.According to an alternative and likewise preferred embodiment of the invention, the front vertical strut and the rear vertical strut of the right strut element and of the left strut element are connected to one another in the upper region by means of an upper longitudinal strut, wherein the left supporting strut element and the right supporting strut element each comprise a supporting element which is fastened to the upper longitudinal strut, wherein the supporting element is provided in the vertically upper region with the fastening interface by means of which the driver's protective roof is detachably fastened to the strut elements. The left supporting strut element and the right supporting strut element are thus each provided with a vertically upwardly extending supporting element to which the driver's protective roof is detachably fastened. As a result, the modularity and variance of the driver's workstation unit is further increased, since differently designed support elements can be used on the two strut elements in a simple manner.According to a preferred embodiment of the invention, the support element is designed as a tubular profile. With a support element designed as a tubular profile, the mechanical requirements for rigidity, stability and strength of the driver's protective roof fastened to the driver's workstation unit can be fulfilled in a simple manner.According to a preferred embodiment of the invention, the vertical strut is in each case designed as a tubular profile or as an angle profile. As a result, the mechanical requirements for rigidity, stability and strength of the driver's workstation unit can be met in a simple manner.According to a preferred embodiment of the invention, the longitudinal strut is designed as a tubular profile or as an angle profile. As a result, the mechanical requirements for rigidity, stability and strength of the driver's workstation unit can be met in a simple manner.According to a preferred embodiment of the invention, the left-hand load-bearing strut element and the right-hand load-bearing strut element are each designed as a welded construction. In such a welding structure, the front vertical strut, the rear vertical strut, and the at least one longitudinal strut constituting the left and right strut members, respectively, are welded together. As a result, the mechanical requirements for rigidity, stability and strength of the driver's workstation unit can be met in a simple manner and the corresponding strut element can be produced in a simple manner. Alternatively, it is conceivable for left and right strut elements, which are formed from the front vertical strut, the rear vertical strut and the at least one longitudinal strut, to be designed as a screw construction in which the vertical struts and longitudinal struts are screwed to one another, or as a plug construction in which the vertical struts and longitudinal struts are connected to one another by plug connections.According to a preferred embodiment of the invention, the front wall is connected to the left-hand supporting strut element and the right-hand supporting strut element in each case by means of a welded connection. As a result, the mechanical requirements for rigidity, stability and strength of the driver's workstation unit can be met in a simple manner.According to a preferred embodiment of the invention, the front cross strut and / or the rear cross strut is connected to the left-hand supporting strut element and the right-hand supporting strut element in each case by means of a screw connection or a welded connection. As a result, the mechanical requirements for rigidity, stability and strength of the driver's workstation unit can be met in a simple manner.According to a preferred embodiment of the invention, the cross-connection element is designed as a tubular profile or as an angle profile.According to a preferred embodiment of the invention, the non-load-bearing cladding element is designed as a sheet metal component, in particular a sheet metal plate, or as a plastic component, in particular a plastic plate. Since the cladding element absorbs and transmits no forces required for the rigidity, stability and strength of the operator's workstation unit, the cladding element can be configured in a cost-effective construction as a sheet metal component, in particular as a thin sheet metal plate, or as a plastic component, in particular a plastic plate.The invention further relates to a push mast stacker comprising a vehicle chassis comprising chassis wheels, a drive drive and a steering drive, and a driver's workstation unit according to one of the preceding claims, wherein the driver's workstation unit can be detachably fastened to the vehicle chassis.The push mast stacker has the advantages already mentioned with respect to the driver's workstation unit.The invention has a number of advantages.The load-bearing strut construction of the operator's workstation unit represents a type of "skeleton" which is formed from tubular profiles and / or angle profiles.
