Typical Applications of the Plastic V-Block LP55-75
The Plastic V-Block LP55-75 was developed for applications where pipes, shafts, round bars or other cylindrical round stock with diameters of approximately 55 to 75 mm need to be stored or staged in a repeatable, organised manner with defined spacing.
Unlike a simple flat support, each component is positioned in its own V-shaped support location. This allows several pieces of round stock to be arranged parallel to one another while reducing uncontrolled rolling or free movement within a storage or load unit.
The three V-shaped supports on the upper side allow three cylindrical components to be arranged evenly within one module. If additional support positions are required on the same level, several LP55-75 modules can be interlocked side by side. This creates longer storage rows with, for example, 6, 9, 12 or more support positions per level.
Typical applications include:
- Organised storage of steel, stainless-steel, aluminium or plastic pipes
- Staging of shafts and axles at machines or assembly stations
- Temporary storage of round bars between individual machining steps
- Order picking of different types of round stock
- Separation and positioning of sensitive or machined components
- Creation of repeatable material staging positions in production
- Multi-layer storage of round stock
- Support of round stock on pallets or within customer-specific load carriers
- Internal transport between production, storage and dispatch
- Integration into reusable and returnable packaging systems
The Plastic V-Block LP55-75 can therefore be used both as an individual V-shaped support and as part of a larger modular storage or transport concept.
Modularly expandable and designed for multi-layer storage
A single Plastic V-Block LP55-75 features a total of six V-shaped contours. Three V-shaped supports on the upper side are designed to accommodate pipes, shafts or round bars with diameters from Ø 55 to 75 mm.
The three corresponding V-shaped contours on the underside are designed for multi-layer storage. When the V-block is placed on top of an existing layer of pipes or shafts, the lower contours engage with the round stock underneath, allowing an additional storage level to be created.
Each V-block can therefore accommodate three parallel pieces of round stock per level.
Several LP55-75 modules can be combined side by side using the interlocking profile. This allows the number of support positions within one level to be expanded flexibly:
- 1 Module: 3 support positions per level
- 2 Modules: 6 support positions per level
- 3 Modules: 9 support positions per level
- 4 Modules: 12 support positions per level
In addition, the V-shaped contours on both sides allow several layers of pipes or shafts to be stacked vertically. The actual permissible number of levels depends on the weight, length and stiffness of the round stock, the number of support points used, and the respective storage and operating conditions.
The modular design is particularly advantageous where production volumes or batch sizes change regularly. Instead of keeping a separate large storage block for each quantity, individual LP55-75 modules can be combined, separated or expanded as required.
Multi-layer storage of pipes and round bars
Thanks to the contours on both sides, the Plastic V-Block LP55-75 can be expanded not only horizontally. It can also be used as an intermediate support between several levels of round stock.
After the first layer of pipes or shafts has been positioned, additional V-blocks can be placed on top and another layer of round stock can then be added. This allows the available storage space to be used more efficiently in height.
However, the possible number of levels cannot be defined universally. It depends, among other things, on the following factors:
- Weight of the individual pipes or shafts
- Length of the round stock
- Number and spacing of the support points used
- Diameter and stiffness of the components
- Condition of the floor or load carrier
- Total height of the stacked arrangement
- Stationary or mobile use
For heavy or long components, the required number of V-blocks and support points should always be adapted to the specific application.
Optional rubber layer for sensitive and machined surfaces
For components with sensitive, painted, ground, polished or coated surfaces, the Plastic V-Block LP55-75 can optionally be supplied with a bonded rubber layer.
The rubber layer serves two functions:
- It reduces direct contact between the round stock and the plastic base body and can therefore help reduce the risk of scratches, abrasion marks and superficial damage.
- It increases friction within the V-shaped support and thereby supports slip-resistant positioning of the inserted round stock.
This type of design can be useful, for example, for precision shafts, ground bars, painted pipes, coated components or other workpieces with sensitive surfaces.
However, the rubber layer does not replace any additional securing measures that may be required for transport applications.
Industries and Applications
The Plastic V-Block LP55-75 is suitable for a wide range of industrial applications where round stock with diameters from Ø 55 to 75 mm is stored, staged or moved within a material flow.
Mechanical Engineering
In mechanical engineering, shafts, axles, precision tubes and round bars can be stored in an organised manner between individual machining steps. The defined V-shaped supports make it easier to assign components and support orderly staging at turning, milling, grinding or assembly workstations.
Metalworking
In metalworking companies, steel, aluminium and stainless-steel pipes as well as round bars are frequently processed in different dimensions. The V-block provides defined support positions and can be used for raw material, semi-finished products or already machined components.
Automotive Industry and Suppliers
At automotive suppliers, axles, shafts, bar stock or tubular components can be positioned within reusable packaging, pallets or customer-specific load carriers.
Pipe and Profile Processing
During cutting, bending, drilling or other machining processes, pipe sections can be placed in defined positions before and after each production step. For long pipes, several rows of V-blocks can be used along the length of the component.
Toolmaking and Fixture Construction
Round stock, guide shafts and cylindrical semi-finished products can be staged in an organised manner according to dimensions or order requirements. This makes it possible to create defined material positions directly at machining and assembly areas.
Storage and Order Picking
In storage areas, the LP55-75 can be used as a reusable support for round stock. The three defined positions make organised storage easier and can support visual inventory control.
Internal Logistics
In recurring material flows between goods receipt, production, intermediate storage and dispatch, several V-blocks can be integrated into pallets, frames or other load carriers.
Reusable Packaging and Closed-Loop Logistics
Thanks to its robust and reusable plastic construction, the V-block is also suitable for closed-loop reusable systems between production sites, suppliers and customers.
Electrical Engineering, Plant Engineering and Equipment Manufacturing
Pipes, shafts, spacers and other cylindrical components can be stored temporarily in an organised manner or prepared for assembly processes.
Combination with Plastic Pallets
The Plastic V-Block LP55-75 can be used on suitable pallets and can therefore form part of a reusable load unit.
Depending on the component length, several rows of V-blocks can be positioned parallel to one another on a pallet. The pallet forms the supporting base, while the V-blocks separate the individual pipes, shafts or round bars from one another and create defined support positions.
Suitable load carriers can be found in our category Plastic Pallets for Industry, Storage and Transport.
For applications with special dimensions or requirements, Custom-Made Plastic Pallets are also available.
Combination with Plastic Pallet Collars
If the load unit also needs lateral containment, the LP55-75 can be combined with suitable plastic pallet collars.
A possible system configuration may consist, for example, of:
Plastic Pallet + Plastic V-Block LP55-75 + Plastic Pallet Collar
The pallet provides the load-bearing base, the V-blocks create defined positions for the round stock, and the pallet collar provides additional lateral containment for the load unit.
For Euro pallets, 1200 x 800 mm plastic pallet collars are available, for example.
Additional Components for Storage and Load Securing
Depending on the application, the Plastic V-Block LP55-75 can be combined with additional components from the Plastic Union product range.
- Plastic Pallet Wedges for Load Securing for larger or differently shaped rollable goods
- Plastic Pallets as the load-bearing base of the load unit
- Plastic Pallet Collars for lateral containment and extension of pallets
- Plastic Interlayers and Separator Sheets for additional separation of individual levels or load units
- Additional Plastic V-Blocks for pipes, round bars, shafts and coils
Load Securing for Round Stock – Technical Classification
Pipes, shafts and round bars place particular demands on storage and transport due to their round geometry. A flat surface alone does not prevent rolling movement.
The Plastic V-Block LP55-75 creates defined V-shaped support points and can therefore help position round stock within a load unit and reduce rolling movement.
However, the V-block alone does not constitute complete load securing. For transport applications, the following factors, among others, must be taken into account:
- Weight and dimensions of the load
- Centre of gravity
- Coefficients of friction between the load, V-block and load carrier
- Number and position of the support points
- Load capacity of the pallet or load carrier
- Strapping or lashing equipment
- Form-fit restraints
- Vehicle and mode of transport
- Route and expected acceleration forces
