Product Description
50KN ETA Storage Drum | Emergency Towing Steel Wire Rope Storage Drum
Product Overview
The 50KN ETA storage drum is a pneumatic drum assembly used for storing emergency towing steel wire rope on vessels that require an emergency towing arrangement. It is intended to keep the specified wire rope organized, protected, and ready for deployment during emergency towing preparation, especially on vessel types such as passenger ships, tankers, and gas carriers where emergency towing readiness is an important safety and operational concern.
This product should be treated as an emergency towing rope storage and handling drum, not as the main towing winch unless the approved project drawing and calculation define that function. The supplied data states a 50 kN safety pull capacity, 100 m drum capacity, 80 mm rope diameter, local control, and pneumatic motor drive. Final rope construction, drum dimensions, foundation design, brake or locking arrangement, certification scope, and emergency towing arrangement interface should be confirmed according to the vessel specification.
Quick Specifications
• Product type: ETA storage drum → stores emergency towing steel wire rope for vessel emergency towing preparation.
• Safety pull capacity: 50 kN → used as supplied pull-capacity data; it should not be converted into SWL, MBL, test load, or towing capacity without project approval.
• Drum capacity: 100 m → rope storage capacity stated in the supplied data; actual rope lay, flange clearance, and drum dimensions should be confirmed by drawing.
• Rope diameter: 80 mm → important for drum groove / winding space, rope handling, and emergency towing arrangement compatibility.
• Drive arrangement: pneumatic air motor → suitable where compressed air supply is available; air supply quality, hose connection, and control logic should be checked.
• Air motor data: 2400 r/min, 9 m³/min air consumption, 7 bar air pressure → key data for ship air-system confirmation before quotation.
• Control position: local control → operation position, emergency stop, brake or lock, and crew access should be confirmed by GA drawing.
• Surface treatment: Sa 2.5 blasting + three layers of epoxy paint → final coating system, DFT, color, and touch-up procedure follow project requirement.

Selection & Inquiry Guide
Step 1: Confirm that the equipment is required as an ETA storage drum for emergency towing steel wire rope, not as a towing winch or lifting winch.
Step 2: Confirm rope specification: diameter 80 mm, rope construction, rope grade, actual length, end fitting, socket / shackle interface, and whether the rope is supplied with the drum.
Step 3: Confirm load terminology and approval basis: 50 kN safety pull capacity, required operating pull, safety factor, brake or locking requirement, and class approval requirement.
Step 4: Confirm the air supply: available working pressure, air flow capacity, air line size, air quality, control valve arrangement, and whether additional air motor documentation is required.
Step 5: Confirm installation interface: deck foundation, footprint, bolt-down or weld-down arrangement, surrounding clearance, rope lead direction, and relationship with chock, fairlead, towing bracket, or emergency towing connection.
Step 6: Confirm surface treatment: Sa 2.5 blasting, three-layer epoxy paint, final color, DFT, corrosion category, touch-up paint, stainless steel option if required, and packing method.
Step 7: Provide vessel type, quantity, classification society requirement, inspection scope, certificate requirement, GA drawing, delivery destination, and required delivery time.
Structure
Single storage drum | Drum shaft | Pneumatic air motor | Local control arrangement | Rope storage area | Support frame / base | Brake or locking arrangement to be confirmed | Deck foundation interface | Marine epoxy coating
Storage, Pneumatic Drive & Engineering Advantages
• The storage drum keeps the emergency towing steel wire rope in a defined location, reducing loose rope handling and supporting faster emergency preparation when the towing arrangement is required.
• The pneumatic drive arrangement avoids dependence on electric drive power at the equipment itself, but the ship air-supply capacity and pressure stability must be checked before final selection.
• The stated 100 m rope capacity should be verified against actual 80 mm rope construction, winding method, flange clearance, and storage condition on the approved drawing.
• Local control allows direct crew operation at the equipment position. Operator access, emergency stop, safe standing area, and rope path should be reviewed with the vessel arrangement.
• The 50 kN safety pull capacity is useful for controlled rope handling, but it is not automatically the towing load, SWL, test load, or rope breaking load.
• Deck foundation and surrounding structure should be checked by the shipyard or design office, because rope handling loads are transferred through the drum base into the ship structure.
• Coating with Sa 2.5 surface preparation and three-layer epoxy paint helps protect the equipment in marine deck conditions when the final coating system is properly specified.
Custom Attributes
• Product Type: ETA storage drum → emergency towing rope storage and handling equipment for ship towing preparation.
• Safety Pull Capacity: 50 kN → supplied pull-capacity term; do not rewrite as SWL, MBL, towing pull, or breaking load without confirmation.
• Drum Capacity: 100 m → rope storage length for the specified emergency towing steel wire rope.
• Rope Diameter: 80 mm → key basis for drum capacity, rope winding, sheave / fairlead compatibility, and end fitting clearance.
• Drive Type: Air motor → suitable for pneumatic operation where ship compressed air supply is available.
• Air Requirement: 2400 r/min, 9 m³/min, 7 bar → air motor data to be checked against ship service air capacity.
• Control: Local control → operation position and safety devices should be confirmed on the approved drawing.
• Material: Mild steel → exact material grades and traceability scope to be confirmed according to order requirement.
• Surface Treatment: Sa 2.5 + three-layer epoxy paint → final coating system follows vessel painting specification.
• Certificate Requirement: Available according to order scope → maker certificate, material certificate, class certificate, and witness inspection should be agreed before quotation.
How It Works
Emergency towing rope is stored on the drum → Crew operates the local pneumatic control → Air motor rotates the drum for rope handling → Rope is paid out or recovered according to the approved emergency towing procedure → Reaction loads are transferred through the shaft, frame, and base into the ship foundation
Applications
Passenger ships | Oil tankers | Gas carriers | Emergency towing arrangement stations | Ship towing preparation | Newbuilding projects | Retrofit and replacement projects
Certifications & Advantages
Certificates can be arranged according to project requirement, inspection scope, material traceability, and classification society approval procedure.
Certification: CCS, NK, BV, ABS, DNV, LR, KR, IRS, RS, RINA, CRS, Makers Test Certificate.

FAQ
Q1: Is the 50KN ETA storage drum a towing winch?
A1: It should not be described as a towing winch based only on the supplied data. The product is written as an emergency towing steel wire rope storage drum. The 50 kN safety pull capacity should be treated as rope-handling pull data unless the approved drawing and calculation define another duty.
Q2: Can the 50 kN safety pull capacity be used as SWL or towing load?
A2: No. The supplied term is safety pull capacity. It should not be changed into SWL, MBL, test load, permissible load, or towing capacity without a manufacturer calculation, project load table, safety factor, and class approval basis.
Q3: What information is needed before quotation?
A3: Confirm rope diameter, rope length, rope construction, drum dimensions, air supply, air motor documentation, brake or locking arrangement, local control layout, deck foundation, surface treatment, certificate requirement, quantity, destination, and delivery time.
