Durable: Our boat slipway winches are built to withstand heavy loads and rough conditions.The specifications of the AQ-JM 30 ton winch include: rated speed 9m/min, drum capacity 400m*42mm (galvanized steel wire rope), electric control box button and remote control. The scheme we provided uses a movable pulley and a fixed pulley, with a 3-fold structure, so that a smaller capacity electric winch can be used to pull a larger-tonnage ship. The weight of the customer’s ship is 250t, and the slope of the slipway is 7.2°. We provided AQ-JM 30 ton slipway winches to a naval base in Nigeria to pull ships ashore for maintenance. The first layer has the largest pulling force and the slowest speed the outermost layer has the smallest pulling force and the fastest speed.ĪQ-JM Electric Slipway Winch A Case of AQ-JM 30 Ton Slipway Winches for A Naval Base in Nigeria The working speed and pulling force of each layer of the electric drum winch are different.Therefore, the layout of the single-drum winch takes up more space. The distance from the single-drum winch to the fixed pulley is about 10 times the length of the drum.When the number of layers of the wire rope exceeds 7 or the deflection angle of the wire rope is greater than 3°, the single drum electric slipway winch will add a rope arranging device.The single drum slipway winch mostly adopts the lower rope. According to the height of the fixed pulley, the single-drum winch can be made into an upper rope or a lower rope.This drum is controlled by the drive torque of the frequency conversion motor, which can better keep in sync with the friction drum.Īicrane AQ-JM single-drum electric slipway winches have less rope capacity than friction-type electric slipway winches, and are more commonly used for small-tonnage ships. The rope storage drum is only used to store the wire rope and does not provide pulling force.The number of rope grooves is generally 6-10. The friction drum set has a rope groove to increase the friction between the wire rope and the drum.The structure of the AQ-JMM friction winch is mainly composed of a friction drum and a rope storage drum. The pulling force and speed of the rope are constant, so the whole machine runs stably and the impact force is small.Friction type winch has no deflection angle of steel wire rope because the position of the rope is unchanged, which reduces the wear of the wire rope and increases the service life of the wire rope.The AQ-JMM friction type electric winch uses the friction between the wire rope and the drum to generate tension. AQ-JMM Friction Type Slipway Winch for Sale The driving method can be electric or hydraulic. We offer different types of slipway winches: friction or single drum.
