Marine anchor windlass is a machine that restrains and manipulates the anchor chain on ships, allowing the anchor to be raised and lowered by means of chain cable, one anchor windlass could have one or two , even three anchor gypsy, which is designed for up to 160 mm anchor chains.
An anchor windlass can be driven by electric motor, or by electric HPU and diesel engine HPU. Standard features include fabricated steel construction, gears hardened to exceed working load requirements, clutched and braked drum and corrosion resistance. Electric, hydraulic or diesel engine drives are available along with warping heads.
Windlasses can be modified to suit customer’s applications and special operating requirements. The anchor windlass has rugged design and heavy duty split bronze bearings. The operating mechanism for brakes and clutches are designed for easy and safe manual operation but may also be remotely operated by hydraulic cylinders. The brakes are easily adjustable. The windlass design provides easy access to all points for lubrication and inspections.
Main components of Fountom Hydraulic Double gypsy anchor windlass
A complete set of hydraulic double gypsy anchor windlass should include steel structure of windlass, hydraulic motors, Gears, hydraulic power unit, control valve group, full set of manual and drawing, special tool and one year spare parts.
Hydraulic Power Unit (HPU)
The hydraulic power unit (HPU) normally consists of four main components: a prime mover (either an engine or electric motor), a pump, a valve, and a reservoir. Each of these components are constructed together and form the main component in a dump trailer’s hydraulic circuit. Together, these components provide the flow (movement) that the system needs to operate. The horse power of the HPU should be large enough to ensure the anchor windlass to finish the anchor lifting job easily. And HPU should have alarm systems.
The hydraulic motor is a key component of an anchor windlass, it must be good in quality and after-sale service, that is why Fountom has adopted the famous brands’ hydraulic motor. The torque and speed of the hydraulic motor is selected according to the design of the load capacity and speed of the windlass.
Hydraulic Control system
The hydraulic control valve group can control the direction, pressure and the flow of fluid and act as a control unit for the hydraulic system of windlass.
