ANCHORING & MOORING SYSTEMS
Hydraulic Mooring Capstans
Compare seven current hydraulic DHC reference models from DHC 1000H through DHC 11000H. Published maximum pull spans 1,000 to 11,000 kg; pressure, flow, return, cooling, speed, drum, rope and duty require system review.

- Vessel name, shipyard or hull number, principal dimensions and equipment number if applicable
- Anchor quantity, type and mass, plus chain length and maximum anchoring depth
- Chain diameter, grade and standard, including DIN 766 or stud-link details
- Required continuous and maximum pull, hauling speed and operating duty
- Horizontal or vertical arrangement, chainwheel quantity, warping head and clutch or brake requirements
- Mooring-rope diameter, construction and minimum breaking load for capstan duties
- Electrical voltage, phase and frequency or hydraulic pressure, flow, return, cooling and filtration
- Deck thickness, foundation, chain lead, chain locker geometry, access and service clearances
- Local, bridge, deck, foot-switch, remote, chain-counter and emergency-stop requirements
- Chain stopper, chain-end fastening and emergency-release requirements
- Flag, class, owner or shipyard documents, inspections and certificates required for the order
- Delivery location, target schedule and installation or commissioning boundary
QUOTATION PROCESS
From vessel data to written scope
Each step narrows the technical boundary and records what is included in the quoted supply.
1. Send vessel and duty data
Share the arrangement, anchor and chain data, pull and speed duty, available power, controls and documentation requirements.
2. Review the complete system
ERBA checks the windlass or capstan together with deck geometry, chain or rope, foundation, drive, controls and support equipment.
3. Confirm the supply configuration
The selected reference, drive variant, chainwheel or drum, accessories and project interfaces are defined for technical and commercial review.
4. Quote the written scope
The quotation states the final make and model, included equipment, documents, warranty path, price, delivery and service boundary.
FREQUENTLY ASKED QUESTIONS
Hydraulic Capstans technical questions
These answers define the reference and quotation boundary; page FAQ markup is owned by the native Elementor accordion.
Confirm the mooring-rope diameter, construction and minimum breaking load, required pull, speed and duty, drum arrangement, available power, deck foundation, controls and documentation requirements.
No. They are technical reference pages. Only ERBA Marine’s written quotation confirms the final make and model, configuration, compatibility, included scope, price and delivery.
No. No blanket certification is claimed. State the flag, class, owner and shipyard requirements so evidence for the exact quoted equipment and order can be confirmed.
Yes. Send the existing nameplate, arrangement and foundation drawings, chain or rope data, power and controls, clear photographs and the required new duty.
No. Published values are reference data for named variants. Final performance and duty depend on the drive supply, chain or rope, deck arrangement, controls, system losses and operating conditions.
Send the vessel, anchor and chain or mooring-rope data, required pull, speed and duty, arrangement, available electrical or hydraulic power, controls, support equipment, documents, schedule and delivery location.
