One definition1. The general term for mechanical equipment installed on outdoor decks.2. Mechanical equipment typically installed on the deck to provide services for ship navigation, mooring, loading and unloading, and towing.II summary:Deck machinery, also known as ship deck machinery, is a mechanical equipment installed on the deck of a ship and is an important component of the ship. Deck machineryIt is to ensure the normal navigation of ships and the mechanical equipment and devices required for ship docking, loading and unloading of goods, and boarding and disembarking of passengersDeck machinery can be divided into large deck machinery and small deck machinery. Mainly including servos, windlass and winch cable guides, and cable pilesDeck machinery such as mooring bollards, cable rollers, etc. generally include servos, anchors, cargo cranes, winches, winches, and boat lifts. stillSuch as catapults and landing devices used to assist in aircraft takeoff and landing, sea supply devices, active anti roll devices and side thrusters used for power positioningVarious types of operating machinery (also known as special machines) such as powerhouses, door opening mechanisms for roll on/roll off ships, suspension bridge retraction devices, as well as towing and net rolling machinesEquipment such as machinery or cabin machinery belong to deck machinery. These machines can be divided into steam, hydraulic, and electric according to the different power sources usedAnd manual (usually small boats and spare parts) machinery, among which hydraulic machinery is more commonly used. The types and types of deck machinery are very diverseThere are many installation locations scattered, and many of them do not work frequently. Some require frequent variable speed and directional operation during work, while others have oneSome special requirements are related to the purpose and navigation waters of the ship....
According to power, it is divided into three categories: manual, electric, and hydraulic.The transmission mechanism for rotating the handle of the manual winch is equipped with a stopper (ratchet and pawl) to keep the heavy object in the desired positionManual winches used for lifting heavy objects should also be equipped with safety handles and brakes. Manual winches are generally used for lifting small weights and equipmentPlaces with poor quality or no power supply.According to their functions, winches can be divided into marine winches, engineering winches, mining winches, cable winches, and so on.According to the roll form, it is divided into single roll and double roll.According to the distribution form of the drum, it can be divided into parallel double drum and front and rear double drum.The main technical indicators of the winch include rated load, supported load, rope speed, rope capacity, etc....
After long-term use, marine cranes need to replace hydraulic oil, which requires certain skills.When replacing hydraulic oil for marine cranes, we can use chemical cleaning agents to clean the oil tank and oil filter once, dry them again, and finally add new hydraulic oil.Is it just that? Prior to this, while the engine is running at low speed, the old oil should be gradually drained, and attention should be paid to constantly replenishing new oil to the oil tank to prevent the oil pump from emptying. The discharged old oil should not flow into the hydraulic oil tank. At this time, new hydraulic oil should be used to gradually drain the old oil in the system circuit until new oil flows out of the oil pipe outlet before stopping the hydraulic pump rotation....
The reason for the slight sticking of the turntable of the marine crane is:1. Check if the bolts are loose 2. Check if there are any problems with the meshing with the small gear or if there are any issues with the drive. 3. Check if the bearings are regularly lubricated with grease, otherwise it indicates severe wear!...
