Overhead crane (full-length luffing crane)

タイトルまたは説明

Product introduction:
High-rise variable-luffing crane with load, this model is a flat-arm type, can be fully variable with load, and the variable-luffing adopts compensating pulleys. The cargo can be moved horizontally. The machine has the characteristics of high operating efficiency, stable operation, and reliable use. This machine can be used as a hook or grab. The variable-luffing crane with load has the advantages of high efficiency, safety and reliability, simple structure, convenient maintenance, low cost, low energy consumption, low noise, and no pollution. It has been widely used in port and terminal loading and unloading operations.
Equipment maintenance:
(1) For the damaged parts of the paint film on the metal structure, the surface of the component should be cleaned and coated with anti-rust paint and decorative paint film to protect the metal surface from rust after rain and snow.
(2) In the movable parts of the crane, such as the connecting pins between the sling and the crane, the guide wheels, the wheels of the trolley, etc., the anti-rust work should be done carefully. After stopping the machine, you can first clean these parts with a brush to remove impurities, moisture, rust spots, etc. that may cause rust, and then use **0 or **0 diesel on these parts. Because **0 or **0 diesel has stronger permeability than engine oil, the loaded hinged parts can penetrate into it, forming an oil film on the metal surface. Because of its low freezing point, it can resist low temperatures.
(3) After cleaning and lubricating with diesel, apply a layer of grease. Calcium-based or lithium-based grease is a good choice, because these two greases have good mechanical stability, adhesion and water resistance, and the freezing point can reach **0 degrees. When applying grease, the coating should not be too thick.
Rust prevention of dock cranes is a key task and cannot be sloppy. Therefore, maintenance and anti-rust work of dock cranes must be done regularly to be effective.
