Definitions

  • the invention relates to an industrial truck lifting mast which has two laterally spaced profile rails which are connected to one another by means of at least two cross members, one of the two cross members being designed as a foot cross member which is arranged in the foot area of the profile rails and at least one further cross member in the vertical direction of the Lifting mast is spaced from the foot cross member, wherein a lifting carriage provided with a load-bearing means is arranged in the profile rails so as to be longitudinally displaceable, and the lifting mast for raising and lowering the lifting carriage in the profile rails is provided with a lifting cylinder device which is supported on the foot cross member, the lifting cylinder device with a lifting means is in operative connection, which is fastened with a first end to the lifting carriage, is fastened with a second end to the lifting mast and is deflected on the lifting cylinder device.
  • Such masts can be used as a standing mast of a single-section mast (so-called simplex mast) or as an extending mast of a multi-section mast, for example a duplex mast, which consists of a standing mast and an extending mast, or a triplex mast, which consists of a standing mast and two extending masts be trained.
  • a lifting cylinder device is provided which is used to raise and lower the lifting carriage in the profile rails of the lifting mast.
  • the lifting cylinder device is supported on the foot cross member and is in operative connection with a lifting means, for example a lifting chain.
  • the lifting means is attached to the lifting carriage at a first end and attached to the lifting mast at the second end. Furthermore, the lifting means is deflected via a deflection roller on the lifting cylinder device.
  • a first cross member is a foot cross member formed, which is arranged in the foot area of the profile rails.
  • Another cross member is designed as a head cross member which is arranged in the head area of the profile rails.
  • Another cross member is designed as a central cross member, which is arranged in the vertical direction of the lifting mast between the foot cross member and the head cross member.
  • the foot cross member supports the lifting cylinder device in the vertical direction. For this purpose, the lifting cylinder device can stand up on the foot cross member with a cylinder base.
  • the lifting cylinder device is fastened to the central cross member, which functions as a further fastening point of the lifting cylinder device and, if necessary, also functions as a safeguard against buckling of the lifting cylinder device.
  • the lifting means deflected at the Hubyzlinder device is here attached with the second end to the central cross member.
  • the central cross member is thus subjected to the tensile force of the lifting means. With such a lifting mast, double the amount of the tensile force of the lifting means is supported by the deflection of the lifting means on the lifting cylinder device on the cylinder base and thus on the foot cross member.
  • a first cross member is designed as a foot cross member which is arranged in the foot area of the profile rails.
  • Another cross member is designed as a head cross member which is arranged in the head area of the profile rails.
  • the foot cross member supports the Lifting cylinder device in the vertical direction.
  • the lifting cylinder device can stand up on the foot cross member with a cylinder base.
  • the lifting means can be fastened with the second end to a cylinder head or a cylinder housing of the lifting cylinder device.
  • a component can be arranged on the cylinder head or the cylinder housing of the lifting cylinder device which serves as an abutment for a chain anchor of a lifting means designed as a lifting chain.
  • the tensile force of the lifting means is introduced directly into the lifting cylinder device.
  • the reaction force on the foot cross member can be reduced, since the simple amount of tensile force of the lifting means that is introduced directly into the cylinder head or the cylinder housing of the lifting cylinder device is the counteracts twice the amount of tensile force from the deflection of the lifting means.
  • the foot cross member experiences a lower load, but the lifting cylinder device is loaded with an additional force.
  • the tensile force of the lifting means is introduced offset relative to the line of action of the lifting cylinder device, so that the lifting cylinder device is not only the Tensile force, but also has to withstand a torque introduced by the tensile force.
  • This can make it necessary to reinforce the cylinder housing, for example an increased wall thickness of the cylinder housing, and the sealing and guiding system of the extending piston rod of the lifting cylinder device must be designed for the higher deformations of the lifting cylinder device.
  • the lifting means can be fastened with the second end on one or both profile rails.
  • a component can be arranged on the profile rail be, for example welded, which serves as an abutment for a chain anchor of a lifting means designed as a lifting chain. In such an embodiment, the tensile force of the lifting means is introduced directly into the rail profiles of the lifting mast.
  • the reaction force on the foot cross member cannot be reduced, since the double amount of the pulling force of the lifting means resulting from the deflection of the lifting means on the lifting cylinder device is supported on the foot cross member.
  • the resulting high reaction force on the foot cross member causes a high load, in particular a high bending load, in the foot cross member and an unfavorable flow of force from the foot cross member into the profile rails. If the foot cross member is connected to the profile rails by a welded connection with corresponding weld seams, this leads to an unfavorable flow of force from the foot cross member via the weld seams into the profile rails.

As a result, both the foot cross member and the further cross member are less stressed.
  • the at least one tensile force-transmitting traction means between the further cross member and the foot cross member also results in a lower load on the welds of these welded joints. Due to the at least one tensile force-transmitting traction device between the further cross member and the foot cross member, only part of the tensile force of the lifting device acts as a resultant force on the further cross member, and on the foot cross member the force introduced by means of the at least one tensile force transmitting traction device directly counteracts the contact force of the lifting cylinder device. As a result, the load, in particular the bending load, is reduced on the foot cross member.

  • two tensile force-transmitting traction means are arranged in the transverse direction of the lifting mast symmetrically to the fastening point of the lifting means on the further cross member. This results in a favorable symmetrical position of the two traction means relative to the force introduction point of the traction force formed by the fastening point of the lifting means Lifting means achieved, which has a favorable effect on the bending load and torsional load of the further cross member.
