What is the STF-Standard Tension Force? The abbreviation STF “Standard Tension Force” stands for the pre-tensioning force also called “Normal Tensioning Force”, which 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 pre-tensioning 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 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

  On this page, you will find frequently asked questions about chain slings. If you are concerned about a question that is not answered here, please do not hesitate to contact us. We will be happy to answer them by mail . What are chain slings? Chain slings are lifting devices comprised of a chain and various types of hooks, links, or attachments. They are used to safely lift and transport heavy loads in industries such as construction, manufacturing, and logistics. What grades does Top Lifting have in its product range? G80 and G100 Lifting Chain slings are available. Sizes from 4mm to 32mm. What is the difference between the individual grades? The difference between the individual grades of chain slings is that the load capacity increases with increasing grade while the material thickness remains the same. What is the tilt angle and how is it measured? The tilt angle is determined by the degrees between an imaginary vertical line and the chain itself. The load-carrying capacity of a

  shackles What are the differences between bow shackle and dee shackle? A bow shackle  and  a dee shackle  are both types of load-bearing  shackles  used in various industries. Here are the main differences between the two: Shape: The most notable difference lies in their shapes. A bow shackle has a rounded "U" shape, resembling the shape of a bow, while a dee shackle has a "D" or horseshoe shape. Load Distribution: The shape of the bow shackle allows for a larger surface area, resulting in a more even distribution of loads across the shackle. This can be advantageous in applications where the load may shift or move during operation. On the other hand, a dee shackle has a smaller contact area, which may concentrate the load more at the ends. Side Loading:  Bow shackles  are better suited for side loading applications due to their shape. The rounded shape of the bow allows the shackle to rotate, reducing stress on the pin.  Dee shackles  are generally not recommende

Operating a  mini lever hoist , also known as a  lever chain hoist , requires proper knowledge and caution to ensure safety. Here is a step-by-step guide on how to safely operate a mini lever hoist: Step 1: Inspect the  Hoist   Before using the mini lever hoist, carefully inspect it for any signs of damage, wear, or malfunction. Check the chain, hooks, lever, and other components for any visible issues. If you notice any problems, do not use the hoist and report it to the appropriate personnel. Step 2: Choose the Correct Capacity  Make sure the mini lever hoist you are using has a sufficient weight capacity to handle the load you intend to lift. Refer to the hoist's user manual or markings to determine its capacity. It is essential never to exceed the hoist's specified weight limit to prevent accidents and equipment failure. Step 3: Prepare the Load  Ensure that the load you are about to lift is properly secured and compatible with the mini lever hoist. If necessary, use suitab

When we use the ratchet strap , maybe we will meet the ratchet strap jammed. So we need to know why it jammed and how to release the jammed ratchet strap. How Ratchet Straps Jam and Get Stuck There are three reasons for ratchet straps jam or get stuck Not disengaging the ratchet all the way: The gear stays locked in place until you unlock it. Winding too much strap on the spool: This requires a little muscle and finesse to unjam. Needs a little lube: Happens with ratchet straps that don't work smoothly from being outside. How to solve these problems? 1) Ratchet Strap Isn't Fully Disengaged and Won't Release When the ratchet is fully closed it's locked into place and both pawls are engaged. When it is partially open both pawls are mostly engaged. You need to get the ratchet fully open in order for it to release. You do this by disengaging the two pawls. First, you need to squeeze the little handle to disengage the manual pawls.

Ratchet straps , also known as  lashing straps  and  tie downs , are one of the most popular methods for securing cargo, especially when it comes to shipping. But are you familiar with the information label that is typically found stitched at the end of the strap? In this article, we examine this ratchet strap label in details. WHAT INFORMATION CAN BE FOUND ON A RATCHET STRAP LABEL? 1. Webbing Material: The webbing material determines the colour of the label. Most used webbing for lashing strap is polyester and the label is the blue colour. 2.Production date: You should be able to find the production date printed on the label, including the month and year. It can be used to trace the strap back to its exact production batch. 3.Lashing Capacity: Lashing capacity (LC) is, essentially, the maximum force your heavy-duty ratchet strap can withstand, without it tearing or damaging in any way. It is usually measured in dekaNewton (daN) and, importantly, it should not be confused
