KONNEX GROUP

About us:


The history of the KONNEX Group is characterized by tradition and a continuous striving for innovation and quality. Its roots go back to 1947, when Roelof Gunneman founded a Dutch trading company. Under his visionary eye, the company continued to develop.

In 1999, the purchase of a renowned importer of Italian chains marked a milestone that led to the change of name to KONNEX B.V.. This change marked the beginning of a new future for the company, expanding its global presence and portfolio of high-quality products.

In 2000, the German KONNEX GmbH was founded in Mettmann, initially with a German partner who imported Load Securing products from China. The path soon led to further development and the company moved its headquarters to Velbert in 2007 to meet its growth requirements.

In 2004, KONNEX Ltd. was founded in China, marking a significant step in the company’s strategic expansion. As a wholly-owned subsidiary, it concentrates on the manufacture of customized OEM Products, focusing on high-quality materials such as metal, plastic or a combination of both. With state-of-the-art production facilities and quality control in accordance with European standard ISO 9001, the plant in China sets benchmarks for efficiency and quality.

In 2013, the KONNEX Group’s position was further strengthened by the acquisition of Ruthenbeck. This strategic decision expanded the company’s portfolio and strengthened its position as a provider of high-quality load securing products.

With the introduction of the LIGHTBELT product in 2018, KONNEX set another milestone, adding an innovative solution for the elevator industry to its product range. This underlines the company’s commitment to continuous development.

With a strong foundation of experience and expertise, the company continues to strive to meet the needs of its customers and set new standards in the industry.

OEM-Quality Products

Our variety of products is legendary and covers all branches of industry – from standard DIN parts to complete assemblies made up of multiple individual parts. We process steel, cast aluminium and precision casting as well as plastics. We design and create stamping and forming tools as well as casting tools for the zinc and plastics sector under the strictest quality control. Through the use of follow-on composite tools, even large series can be produced under excellent conditions.

Load securing

KONNEX Load securing – In our range you will find many high-quality products that are essential for securing a load in accordance with regulations. We have the right end fittings for every strap width, such as pointed hooks, triangles and snap hooks: Pointed hooks, triangles and snap hooks. You can also expect a very large selection of selected ratchet products.

Terminology in cargo securing

Pressure Ratchet

Units of measurement: 
1 kg = 9.80665 N
1 daN (Dekanewton) =  10 N ≈ 1 kg
50 kN = 5.000 daN ≈ 5.000 Kg = 5.0 t

STF – Standard Tension Force

The abbreviation STF “Standard Tension Force” stands for the pretensioning force also called “Normal Tensioning Force”, this describes the force of the lashing strap. Put simply, with an STF value of 350 daN: you pull or push on a ratchet lever with exactly 50 daN (SHF) and can lift/move a weight of 350 kg with this force. The main reason for high pretensioning forces are the high-quality products, in this case the ratchet and the lashing strap, which have been optimized for your application. The STF value to be achieved is defined by the European standardization: STF = min. 0.1 x LC and max. 0.5 x LC

Cam buckles and heavy-duty pressure ratchets
The specification of the normal hand force (SHF) and the normal tension force (STF) can be omitted on labels of lashing straps with cam buckles if these lashings are not designed by the manufacturer for the intended use – tie-down lashing.

Cam buckle
As a rule, no or only slight tensioning forces are achieved with cam buckles, so that the intended use is limited to direct lashing procedures or bundling.

Heavy-duty pressure ratchets
The same applies mutatis mutandis to many heavy-duty lashing straps with nominal widths of 75mm to 100mm. The tensioning elements used in these lashing straps also generally do not achieve any useful tensioning forces for the intended use – tie-down lashing, but are used for direct lashing due to their high LC values.

* All products in our assortment of cargo safety are tested according to DIN EN 12195-2. STF – Standard Tension Force according to DIN EN 12195-2, always applies to a lashing belt system (ratchet, webbing and end fittings). The
webbing, its length, composition, elongation, sewing and material thickness have a very large influence on the STF value of a lashing belt system. The STF value for pull- and pressure ratchets is given by us only for guidelinde.

LC (Lashing Capacity)STF min.STF max.
400 kN40 daN200 daN
750 kN75 daN 375 daN
1000 kN100 daN 500 daN
1500 kN150 daN 750 daN
2000 kN200 daN 1000 daN
2500 kN250 daN 1250 daN
3500 kN350 daN 1750 daN
5000 kN500 daN 2500 daN

Example:
71CQ050 Pressure Ratchet 50mm – 50kN
Breaking Strength (BS) 50 kN = LC 25 kN (1/2 BS)
The STF value here must be between (0,1 x LC) 250 daN and max. (0,5 x LC) 1.250 daN.

A two-part tensioning belt consists of one tensioning element: a pressure or pull ratchet, webbing and end fittings. A tensioning belt is divided into a loose end and a fixed end. Both parts are marked with a label in accordance with the DIN EN 12195-2 standard, so that the product can always be traced precisely.

Both the fixed end and the loose end have an end fitting, e.g. a pointed hook, flat hook or snap hook, these are thoroughly selected depending on the application.

The tensioning element is called a pressure ratchet or pull ratchet

The most commonly used ratchet is the pressure ratchet whose STF value (Standard Tension Force) reaches values up to 350 daN. If more force is required, an ERGO long lever ratchet, also known as a pull ratchet, is used, which achieves STF values of up to 800 daN, depending on the design.

Arrangement for testing the pre-tensioning ability (STF) of Pressure – and Pullratchets

SHF – Standard Hand Force

The abbreviation SHF “Standard Hand Force” describes the force (50 daN) that must be applied to the ratchet lever according to the European standardization (DIN EN 12195-2) in order to determine the STF value for the system (ratchet, lashing strap and end fittings). This force is also called hand force – force of the user.

ERGO Pull Ratchet

LC – Lashing Capacity

The value LC “Lashing Capacity” stands for the permissible lashing force. It indicates when the load limit for the lashing system in straight pull (direct pull) is reached. This value is determined from the breaking strength.

Example:
71CQ050 Pressure Ratchet 50mm – 50kN
Breaking Strength (BS) 50 kN = LC 25 kN (1/2 BS)

LC – direct pull

Example: Pressure Ratchet 50mm – 50kN
LC = 2.500 daN

two-piece lashing strap
– Ratchet
– Fixed end with end fitting
– Loose end with end fitting

LC – strapping

Example: Pressure Ratchet 50mm – 50kN
LC = 5.000 daN

one-piece lashing strap
– Ratchet
– Lashing strap
two-piece lashing strap
– Ratchet
– Fixed end with end fitting
– Loose end with end fitting

Direct pull / Strapping

If very heavy loads are involved, they are secured by direct pull. In the case of direct lashing, the lashing straps are attached to the load’s attachment point and to the lashing points on the loading surface. In contrast to strapping, the load is not pressed against the truck floor.

Direct pull

Strapping is a non-positive load securing method. In this case, the belts are placed around the load and tensioned, pressing the load against the floor. To prevent damage to the load or the lashing straps, edge protectors are used here.

Strapping

Label explanation
  • PES (Polyester) = blue label
  • PA (Polamid) = green label
  • PP (Polypropylen) = brown label
