Pulling Grips

Pulling grips are flexible steel wire mesh sleeves that hold a cable, रस्सी, pipe or duct so it can be pulled, lowered or tensioned. Slide the mesh over the end, आंख को तनाव देना, and the weave closes radially on the jacket: the grip tightens as the pull load rises, so nothing has to be clamped or bolted to the cable. We braid them in our own workshop in galvanised steel or AISI 304 / 316 स्टेनलेस तार, for cable from 9 मिमी से 160 मिमी, with single, दोहरा, लचीला, घूमती या ऑफसेट आँखें.

This page covers the range as a whole: how the mesh holds, which of the five constructions suits the pull you are doing, how to size a grip from the cable diameter and the expected line pull, and what the capacity on the label actually means. Each construction has its own page, linked from the table below.

How Wire Mesh Pulling Grips Hold a Cable

There is no mechanism inside a pulling grip. The grip is the weave, and it works in three stages:

1. इस पर फिसलो. जाल को फैलाएं और इसे केबल के सिरे पर तब तक धकेलें जब तक कि केबल आंख तक न पहुंच जाए. The mesh has to sit on the full gripping length, not just on the cable tip.
2. Tension. Load on the eye lengthens the tube slightly and contracts it radially. Every wire in the weave closes on the jacket at once, so the pulling force becomes a uniform clamping force along the whole mesh.
3. मुक्त करना. लाइन को ढीला करें और जाल को आगे की ओर धकेलें; the weave opens and the grip slides off. कोई उपकरण नहीं, कोई निशान नहीं, no cut jacket.

Because the load is carried by friction spread over the mesh length, capacity comes from engagement length and the number of mesh layers, not from wire gauge alone. ए 3.0 mm wire in a 300 mm mesh holds less than a 2.0 mm wire in a 1200 मिमी जाल. That is also why a pulling grip can drag a lead-sheathed or thin-wall cable that a clamp would crush, and why the same grip releases without leaving a mark.

Five Constructions, One Principle

Every type below uses the same wire mesh principle. What changes is the head, the way the grip closes, and the material – and those three things decide which pull it suits.

Material is a separate choice: the closed-head range is available in galvanised steel, ऐसी 304 या 316 स्टेनलेस.

Sizing a Pulling Grip: Three Numbers

Three measurements decide the model, and getting them wrong is the usual reason a grip slips on the first pull.

• The true outside diameter where the mesh will sit. Measure over the jacket, over any tape or bedding, and over the whole bundle if you are pulling more than one cable. Nominal size is not the gripping size.
• The mesh length you can engage. A grip needs at least four to five times the cable diameter in mesh contact. Less than that and the load concentrates at the head.
• The expected line pull at the worst point of the run – start of pull, through bends, up a slope. The published capacity is a working load; keep the pull below it and add margin on a wet, greasy or polished jacket.

Standard range shown. Mesh up to 3000 mm and diameters outside this table are made to order.

Standard Range and Pulling Capacity

The chart below is the standard galvanised range. Capacity is quoted as a working load with a 5:1 तोड़ने की ताकत पर सुरक्षा कारक, measured with the mesh fully engaged on a clean, dry cable.

A wet, oily or highly polished jacket reduces friction and therefore capacity – confirm the rating for those conditions before the first pull.

Pulling Grips – विनिर्देश

Eye and Head Options

The head decides how the pulling line meets the grip, and it is the part that has to pass a duct mouth, a sheave or a manhole cover.

• Single braided eye – एक लूप, for a straight pull in a clean duct.
• दोहरी आँख – two loops for lashing, or for two lines pulled in line.
• लचीली आँख – a swaged ferrule eye that articulates, so the grip stays aligned through bends.
• घूमती हुई आँख – lets the cable spin out its own lay on long runs without twisting the mesh.
• ऑफसेट आँख – keeps the line clear of the duct wall where headroom is tight.
• तिरछी आँख – a hard wear surface inside the eye where it rubs a hook, shackle or winch line.

Galvanised, Stainless or Non-Metallic

Material is decided by the environment the grip works in, not by the pull load.

What the Capacity on the Label Means

Every grip is rated at a 5:1 सुरक्षा कारक on its breaking strength, so a CPS-50 with a 2,500 kg capacity has been built to hold about 12,500 kg before it fails. The 2,500 kg figure is the working load: it is what you are permitted to pull, not what the grip can survive.

Two practical consequences. पहला, do not use the breaking strength as a target – a grip taken to its break has already damaged the cable and the mesh. दूसरा, a pulling grip is a pulling and holding tool, not a lifting sling: unless the model is rated and marked for lifting, keep it on the horizontal pull, the duct and the cable drum.

Fitting and the First Pull

1. जाल का निरीक्षण करें, प्रत्येक उपयोग से पहले आँख और सामी – टूटे हुए तार, a deformed eye or a slipped ferrule retire the grip.
2. Expand the mesh fully and slide it on until the cable end reaches the eye. Half-engagement is the most common cause of a pull that lets go.
3. खिंचाव को जाल अक्ष के अनुरूप रखें; side loading concentrates the grip on one edge of the weave.
4. Take up the slack slowly and watch the mesh close. If it slips at low load, the grip is too large for the diameter or the jacket is too smooth – stop and re-size rather than pulling harder.
5. कभी भी निर्धारित क्षमता से अधिक न हो, and never stand in line with a loaded pull line.

निरीक्षण एवं सेवानिवृत्ति

• Broken or lifted wires anywhere in the weave – the grip has lost section and capacity.
• A deformed, stretched or opened eye, or a ferrule that has slipped on the rope.
• Corrosion pitting on galvanised mesh, or a coating worn through to bare wire.
• Mesh that no longer closes on the cable, or that has been pulled out of shape.
• Any grip involved in a slip or an overload: इसे रिटायर करो, do not re-use it on a lighter job.

Record the pulls and the damage. A grip is cheap next to the cable it is pulling, and a mesh that has been dragged through a rough duct mouth is not the same grip it was on the first pull.

अक्सर पूछे जाने वाले प्रश्नों

What are pulling grips used for?

Holding a cable, रस्सी, pipe or duct so it can be pulled, lowered or tensioned. The mesh closes on the jacket as the pull load rises, which spreads the gripping force along the cable instead of clamping it at one point.

Is a pulling grip the same as a cable sock?

हाँ. Pulling grip, केबल मोजा, केबल मोजा, mesh grip and pulling stocking all describe the same article: a braided wire mesh tube with an eye at the head. The names come from different trades – cable jointers say sock, riggers say grip.

मैं आकार कैसे चुनूं??

Measure the true outside diameter where the mesh will sit, then check that the model’s range covers it and that you have at least four to five times the diameter in mesh engagement. A grip that is too large slips; one that is too small will not slide on.

How much can a pulling grip hold?

The standard range runs from 750 kg on the CPS-16 to 8,000 kg on the CPS-160, quoted as working loads at a 5:1 सुरक्षा कारक. क्षमता केबल की सतह पर निर्भर करती है, mesh length and the number of mesh layers, so confirm the figure for your cable before the first pull.

Will a wire mesh grip damage the cable jacket?

Not in normal use. The load is distributed over the mesh length rather than concentrated, which is why grips are used on lead sheath, thin-wall insulation and fibre. चित्रित के लिए, polished or stainless pipe, specify a PVC or rubber coated mesh to avoid surface marking.

Can I fit one to a cable that is already installed?

हाँ – use a lace-up or split mesh grip, which is wrapped around the cable and laced closed instead of being slid over a free end. देखें lace-up hoisting grips पेज.

Can a pulling grip be used for lifting?

Only if the model is rated and marked for lifting. A standard pulling grip is a pulling and holding tool; using an unrated grip as a lifting sling puts a factor of five between the load and a failure that no one has calculated.

Can you make a custom length, eye or branded grip?

हाँ. Mesh length from 300 मिमी से 3000 मिमी, cable diameters outside the standard range, अकेला, दोहरा, लचीला, rotating, offset or thimble eyes, coated colours for size coding, logo marking and private-label packing.
