Rope type crane load cells (overload protection)
Rope type load cells
Elfatek rope-type load cells for crane overload protection: clamped on the hoist rope, they measure the rope tension and signal the control unit before the crane lifts too much.

A crane load cell measures the weight on the hook so the crane cannot lift more than its rated load. Elfatek ELS rope-type load cells are clamped onto the hoist wire rope: they measure the tensile force on the rope and send a warning signal to the control unit in overload conditions.
Because the cell sits on the rope, it can be fitted to new cranes and added to existing rope cranes without changing the hoist. Elfatek makes the ELS cells from special alloy steel for crane overload systems in demanding industrial environments.
Elfatek rope-type load cell models
| Model | Capacity | Rope diameter | Dimensions (L × H × W) |
|---|---|---|---|
| ELS-LC3T-08 | 3 t | Ø8 – Ø12 mm | 170 × 56 × 40 mm |
| ELS-LC3T-12 | 3 t | Ø12 – Ø22 mm | 170 × 56 × 40 mm |
| ELS-LC3T-22 | 3 t | Ø22 – Ø32 mm | 170 × 56 × 40 mm |
| ELS-LC5T-08 | 5 t | Ø8 – Ø12 mm | 170 × 56 × 40 mm |
| ELS-LC5T-12 | 5 t | Ø12 – Ø22 mm | 170 × 56 × 40 mm |
| ELS-LC5T-22 | 5 t | Ø22 – Ø32 mm | 170 × 56 × 40 mm |
| ELS-LC10T-22 | 10 t | Ø22 – Ø32 mm | 250 × 82 × 64 mm |
The capacity is the tension on the rope where the cell is mounted, not always the crane capacity: on a hoist with several rope falls the rope carries only part of the load. Our engineers choose the model from the reeving, rope diameter and rated load of your crane.
How a rope-type load cell is installed
- Choose the mounting point – usually the fixed (dead) end of the rope, where the rope does not run over the cell.
- Fit the load cell with its rope clamp, clamp screw and guide support on the rope.
- Connect the cable to the overload control unit using the colour code: red +EXC, yellow −EXC, green +SIG, white −SIG.
- Calibrate with a known test load and set the warning and cut-off points.
- Test that hoisting up stops at overload while lowering stays possible.
Load cell, overload protection and safety
- Protects the crane structure, hoist, rope and hook from overload.
- Protects people under the load – overload is one of the main causes of crane accidents.
- Works with Elfatek wireless remotes and crane control panels.
- Should be checked and recalibrated during periodic crane inspection.
Questions and answers
What is a load cell for cranes?
A sensor that measures the load on the hoist so the overload system can warn and stop hoisting before the crane lifts more than its rated load. Elfatek ELS rope-type load cells measure the tension on the wire rope.
Which Elfatek load cell models does TMA supply?
Rope-type load cells ELS-LC3T (3 t), ELS-LC5T (5 t) and ELS-LC10T (10 t), for rope diameters from Ø8 to Ø32 mm depending on the model.
Can a load cell be added to an existing crane?
Yes, on rope cranes: the rope-type cell is clamped onto the wire rope and connected to an overload control unit, without changing the hoist.
Where is a rope load cell mounted?
Usually on the fixed (dead) end of the hoist rope. Our engineers choose the point and the model from the rope diameter and reeving of your crane.
Do you supply Elfatek crane load cells in Egypt and Saudi Arabia?
Yes. TMA supplies Elfatek crane load cells to factories and warehouses across Egypt from our office in Nasr City, Cairo, with installation and after-sales service in Egypt, and we also supply customers in Saudi Arabia. Send your requirements on WhatsApp or through the quotation form.
