  • Load suspension device for the automatic quick lifting and lowering of Charge units, suitable. Simplifying and facilitating load handling and load settling and a high turnover speed are possible if the transport unit, e.g. the gantry pallet truck does its job without a driver can, for which an automatic picking up and setting down of the cargo units Requirement is.
  • the aim of the present invention is to provide a load suspension device for automatic Developing pick-up and depositing of the cargo units, besides that Use as a conventional spreader - especially for use in a driverless Gantry pallet truck is suitable, the load handler in front of the Load pickup floating load-oriented automatically onto the load unit, e.g. attaches the ISO container and the load with low vibrations after the load has been picked up transported.
  • the invention proposes that the support frame on its spaced-apart longitudinal spars on both sides and parallel to it Longitudinal axis is provided with guideways on which two are transverse to Load carriers extending along the longitudinal axis of the support frame and parallel to one another are slidably and parallel to themselves adjustable, the Fastening device for coupling the load handler to the load unit are provided on the load carriers.
  • the essence of the present invention is in the two independent and mutually adjustable load carriers that The setting of the load handler can be moved on the guideways allows different lengths of the cargo units.
  • the support frame according to the invention is particularly favorable on one of driving and Hoist of existing driverless gantry pallet trucks can be raised and lowered, whose hoist consists of vertically arranged jacks is, in which lifting drives connected to the support frame are provided.
  • the Invention therefore uses a relatively simple one for the most varied
  • the container sizes are adjustable and the frame is lifted and lifted in the straddle carrier can be lowered so that the load can be transported without swinging can be.
  • each jacks each wear the support frame in pairs on both sides in the area of the longitudinal spars, the the guideways receiving parts of the longitudinal spars in the vehicle longitudinal direction cantilever on both sides of the jacks and the load carriers symmetrical to the center of the Carrying the straddle carrier adjustable.
  • the support frame is preferably in the Top view designed essentially H-shaped. Through the beam-shaped load carriers and their adjustability on the guideways becomes a load handler created that weighs significantly less than a conventional spreader.
  • the support frame is coupled to piston-cylinder units, which are the linear actuators Form lifting supports and lift and lower the support frame without swinging.
  • the load carriers are adjusted by that racks are provided on the guideways, in which the for Adjustment of the distance between the two load carriers at both ends of the Engage the load carrier provided synchronously driven pinion.
  • the pinions Roll the same onto the Racks and thus moving the load carrier parallel to each other on the desired length of the loading unit or container size.
  • the guideways are as Slideways formed on which are provided at the ends of the load carriers Sliding shoes supported resiliently against the load carrier when receiving the Charge unit can be placed.
  • each Load carrier two at a distance, which can be hooked into the openings of the corner fittings mutually changeable, hook-shaped bolts that can be moved in a bolt guide intended.
  • hook-shaped bolts that can be moved in a bolt guide intended.
  • the hook-shaped bars are spaced apart changeable, according to the invention piston-cylinder units between the hook-shaped bars are provided.
  • the bolt guide receiving the hook-shaped bolt is also in The longitudinal direction of the load carrier is limitedly guided on it, so that also Inclinations of the cargo unit to be accommodated can be compensated for within limits.
  • An advantage of the present invention is that the cost of the innovative load handling device is approx. 50% lower than in comparison to conventional spreaders.
  • the lifting device that is half the weight, paired with the low transport weight of the straddle carrier significantly increases this Load weight of the device.
  • the load handler is simple in construction, Reliable and inexpensive to manufacture.
  • the straddle carrier according to the invention is designated by 1 and shown in the transport position "empty run".
  • the straddle carrier consists of two parts, the chassis 1a and the hoist 1b.
  • the level of Portal pallet truck 1 changes, apart from the deflection of the tires different loading conditions are not.
  • On the chassis 1a that's four Lifting supports 2 existing lifting gear recognizable, on which the horizontal support frame 3 is raised and lowered attached.
  • Serve to raise and lower the support frame 3 the piston-cylinder units 4, which with the support frame 3 in a manner not shown are coupled and enable its raising and lowering.
  • the distance between the load carriers 6 is set to the length of a 45 ft ISO container 7 below the Support frame 3 is parked on the floor.
  • the straddle carrier 1 was over the ISO container 7 driven so that the load carrier 6 in the region of the longitudinal edges 8 of the ISO containers 7 are positioned.
  • the fastening means 9 are on the load carriers 6 arranged for the ISO container 7, as will be described later.
  • FIG. 3 shows schematically how the load carriers 6 are lowered together with the support frame 3 on the jacks 2 of the hoist Fasteners 9 the ISO container 7 picked up and lifted from the floor to have. In this position, the straddle carrier 1 can swing the ISO container 7 transport and take it to its destination.
  • the load carrier 6 by moving on the guideways 5 of the longitudinal spars of the support frame 3 on the different container dimensions are adjustable; in the example can by the different positions of the load carriers 6 in the closest distance a 20 ft ISO container 7 as well as in the widest position of the Load carrier is a 45 ft ISO container 7. As can also be drawn with a dash-dot line a 40 ft ISO container 7 can also be accommodated. In the right half of the Figure 4 shows the ISO container 7 on the chassis 10 of a Truck raised to be lowered onto this.
  • the drawing figure 5 shows a top view of the straddle carrier 1 Guideways 5 on which the two load carriers 6 are displaceable.
  • the guideways 5 Racks 11 assigned, in the pinion arranged at the ends of the load carrier 6 12 engage and enable a synchronous displacement of the load carrier 6.
  • the pinions 12 are on a common shaft 13 arranged, which is driven in rotation, not shown.
  • the load carriers 6 are on both sides Slide shoes 14 resiliently mounted, the spring elements 15 having a spring characteristic get, which is designed so that after compression by the weight of the Load carrier 6 this remains freely horizontally displaceable.
  • the slide shoes 14 now take over the load and guide the resulting forces into the guideways of the Side rails of the support frame 3.
  • the latch 20 is hydraulic by means of cylinders 21 in the form of pliers horizontally in the direction of the ISO container 7 have been pulled, the hook-shaped ends 22 of the latch 20 in the side openings of the container corner fitting have penetrated.
  • the piston-cylinder units 4 in the jacks 2 are extended and lift the Support frame 3 with the on the load carriers 6 via the fastening means 9 attached ISO container 7 up to the operative height.
  • By pressing the Cylinder 23 can lock guide 19 horizontally by a certain amount be moved. In this way, one can also move to the vehicle's longitudinal axis Asymmetrical load suspension within limits, which can also result from a diagonal position of the ISO container 7 can result.
  • Support frame 3 also like a conventional spreader with four here Attachment points 24 can be used for hoisting ropes 26.
  • the suspension on different handling equipment is unchanged from the conventional spreader, so that an easy exchange is possible.
  • An aggregate 25 is in the center of the Support frame arranged, which is the drive energy for the piston-cylinder units and delivers the rotary drive of the pinion.
  • Four-point suspensions are other types of attachment between the lifting device and Spreader possible, e.g. Slewing rings or central hooks.
