The Camlok TTB spreader beam is a specialist lifting attachment for handling bulk bags — also known as FIBCs (Flexible Intermediate Bulk Containers) or "big bags" — by overhead crane. The 1090 mm spreader beam keeps the bag's four lifting loops separated under load, preventing the loops converging on the crane hook and ensuring the bag opens stably for safe transport and discharge. Rated at 2000 kg WLL, it suits the majority of FIBC sizes used in industrial bulk handling.
Key Features
- Four-point spreader design — keeps the bag's four lifting loops separated under load, preventing convergence on the crane hook and maintaining bag shape during transport.
- 1090 mm beam length — suits the majority of standard FIBC sizes used in industrial bulk handling.
- 2000 kg WLL — covers most bulk bag applications in cement, aggregates, agricultural products, chemicals, and similar bulk goods.
- Crane attachment — integral lifting eye for direct crane connection via a suitably rated shackle.
- Steel construction — designed for daily industrial bulk-bag handling.

CE Marked, UKCA Compliant & LOLER 1998 Ready
The Camlok TTB spreader beam is CE marked, UKCA compliant, and manufactured to relevant European lifting standards. Fully compatible with LOLER 1998 and PUWER 1998 when correctly used and inspected. Supplied with certification, identification, and operating instructions.
Suitable Applications
Lifting and transporting bulk bags / FIBCs by overhead crane in construction (cement, sand, gravel), agriculture (fertilisers, grain), chemical processing (powdered chemicals, polymers), food manufacturing (flour, sugar, starches), recycling, and waste handling. The spreader keeps the bag stable during lifts, transport, and discharge into hoppers, silos, or mixers.
How to Use Safely
- Inspect the spreader beam before each use. Check the beam, four corner connection points, lifting eye, and any included shackles for damage, wear or corrosion. Do not use if defects are found.
- Verify the bag's gross weight (bag + contents) does not exceed the rated 2000 kg WLL of the spreader.
- Position the spreader directly above the bag. Lower the four lifting loops over the spreader's four corner attachment points one at a time, ensuring each loop is fully seated.
- Verify all four loops are correctly engaged and the bag is hanging symmetrically under the beam.
- Attach the crane hook (with shackle if required) to the spreader's central lifting eye. Confirm hook safety latch is engaged.
- Lift slowly to a low test-lift height. Confirm all four loops remain engaged, the bag is hanging level, and there is no slippage or excessive deformation of the bag.
- Proceed with the lift, maintaining slow controlled motion. Do not allow the bag to swing or rotate uncontrolled.
- For discharge: position the bag over the receiving vessel, release the bottom spout (if fitted), and allow the contents to discharge under gravity.
- After discharge or landing, fully relieve load before disengaging the four loops from the spreader corners.
Inspection and Maintenance
A visual inspection is required before every use. A thorough examination by a qualified engineer is required at least every 6 months in regular use, in accordance with LOLER 1998. Records of examination must be kept. Refer to the manufacturer's manual for detailed inspection and maintenance instructions, derating factors for use, and replacement schedules for any wearing components.

Frequently Asked Questions
Q: Why do I need a spreader beam to lift a big bag?
A bulk bag's four lifting loops want to converge on the crane hook when lifted directly. This collapses the bag's shape, can cause loops to slip off the hook, and makes the bag unstable during transport. A spreader beam holds the four loops apart at a fixed spacing, keeping the bag open, square, and stable throughout the lift.
Q: What size of big bag does the TTB suit?
The TTB 2.0 / 1090 has a 1090 mm spreader length, which suits most standard FIBC sizes (typical bags are 900–1100 mm square). It is rated for bags up to 2000 kg gross weight. For non-standard bag sizes, verify your bag's loop spacing fits the beam length.
Q: Can I use the TTB with a forklift instead of a crane?
No. The TTB is designed for overhead crane attachment via the central lifting eye. For forklift-based bulk bag handling, separate forklift bag handling attachments are available.
Q: How often should the spreader beam be inspected?
A visual inspection is required before every use. A thorough examination by a qualified engineer is required at least every 6 months for spreader beams in regular use, in accordance with LOLER 1998. Records of examination must be kept.
