Description

The The present invention relates to the problem of load securing of mini excavators and excavators on trailers, containers and vehicle loading floors whose fast and uncomplicated loading and unloading and effective fixation during the Transport and transfer journey. The generic term is the positive and non-positive load securing of Mini excavators on a transport trailer or vehicle loading floor designated.

For the transport Mini excavators and excavators are primarily vehicle trailers, containers and vehicle loading floors (Vehicle bodies) used, whose function previously in a non-positive load securing consists of straps and lashing chains. The complicated procedure and the sometimes insufficient and missing lashing points represent the Again and again, transporters face complicated and unsolvable tasks in the area of proper load securing. Despite legal regulations are on and on transport systems, as well as insufficient attachment points on the construction machines. Any load securing is therefore a compromise and is in many cases unsatisfactory.

A Interlocking Cargo securing is in any case the optimal and desired System. In conjunction with traction can form a positive load securing represent a double and perfectly adequate load securing, the meets all requirements in transport. The lateral centrifugal forces, the Starting and braking forces is to counteract so far that the charge - in this case a mini excavator or excavator - not slipped, overturned or falling down.

Of the Invention are based on several factors. These relate on a positive load securing, the one forward, regression and prevent lateral movement of the minibagger / excavator. In addition, a non-positive Load securing required, which increases the contact pressure on the bed and counteracts overturning.

The Requirements are made by a Abstützschildfixierung and two Bracket over the crawler chassis Fulfills. The positive side effect is the fast assembly and disassembly the headband and the use of technical possibilities (Raising and lowering of the support plate on the excavator) for the form-fitting Load securing. A flexible adjustment allows the use of load securing for different Excavator types of similar size and design.

at an o.g. Invention for positive and non-positive load securing is they are simple technical solutions, the on each vehicle trailer, Container or vehicle body taking into account the vehicle's useful mass and manufacturer releases retrofitted can be. The application limits are only payload, weight and Expenses of the vehicle, excavator and the stirrup construction firmly. Technical changes on Vehicle or body are subject to acceptance, require a report and technical operating permit. The sizing and technical execution The load securing is based on the generally valid rules the VDI 2700, the necessary lashing and holding forces, the Weight of the load and manufacturer approvals.

The The invention is explained in more detail below with reference to the drawings:

1 shows the top view of a transport trailer for minibag / excavator

2 shows the side view of the transport trailer with the contour / position of a minibagger / excavator in transport position

3 shows the rear and / or front view of the transport trailer with the outer contour / crawler chassis of Minibaggers / excavator

The transport trailer consists in this case of a two-axle chassis 16 2 , with rear ramps 2 , a rear support 3 and a front toolbox 12 1 and 2 and can be used flexibly for mini excavators / excavators or other transports. Hook lift containers or vehicle load floors (vehicle superstructures) can be constructed in a similar and similar manner and correspond to the same usage.

In the 1 shown top view shows the mini excavator / excavator in transport position on the trailer with turned backwards boom 1 and lowered bucket 11 , The crawler chassis 8th (Rubber chain) is in consideration of the center of gravity on the optimal center of the trailer.

The components of the load securing are the side-mounted flat iron 6 that between the ship's side reinforcements 4 was welded. The flat iron 6 was through hole arrangements 1 drilled in the front and rear flat iron area to the U-bolts 7 1 . 2 and 3 to attach so that the headband 18 3 the crawler chassis 8th (Rubber chain) hold down firmly on the loading area and form-fitting sideways to the loading area. An adjustment and displacement of the headband 18 on the hole arrangements is possible.

The headband 18 1 and 3 be in the hole arrangements with threaded bolts and U-bolts 7 3 fixed and tightened so far that the crawler chassis 8th on the loading floor 3 is clamped non-positively. The headband 18 are designed so that when in the direction of travel or reverse-rotated superstructure 2 , the headband 18 3 can not be removed. A lock on the U-bolts 7 also ensures an "additional anti-theft device".

On the retaining clips 18 3 are angle iron 5 attached, the lateral displacement (positive engagement) of the crawler chassis 8th 3 at a total of 4 points 1 prevent. With flexible trailer and cargo use these angle iron 5 be made laterally adjustable.

Mini excavators and excavators usually have a support plate 9 1 and 2 and / or Abstützpratzen. These are hydraulically lowered or raised for support and transport travel. The system is used in conjunction with fixed "load skids" - in this case a Abstützschildfixierung 10 2 - An effective form-locking load securing the braking and starting movement of the load effectively and with their own technical possibilities. The Abstützschildfixierung 10 2 is the size of the support plate 9 2 adapt or interpret adjustable.

The loading (driving) of the transport trailer, container or cargo area is basically carried out with the boom tilted counter to the direction of travel 1 (for support when tilting). The front support plate 9 2 is in the raised state and only after reaching the transport position in the Abstützschildfixierung 10 2 drained.

The uppercarriage of the minibagger / excavator 15 is rotated 90 degrees.

The retaining bracket for chain fixation 18 3 are put on the chains and the U-bolts 7 dressed.

The uppercarriage of the minibagger / excavator 15 is turned back 90 degrees 2 ,

The boom arm 1 is lowered kinked, the backhoe 11 placed on the loading area and the ramps 2 in transport position 1 brought.

The U-bolts 7 are to be checked tightly, the superstructure 15 to fix in the transport position, the rear supports 3 retract and the ramps 2 in transport position 1 bring to.

to additional increase Stiction and lateral stabilization between crawler tracks and loading floor, the use of a non-slip mat is recommended.
