What is a movable ladder?
Loading Arm Movable ladder, also known as a loading arm movable ladder in specific industrial applications, is a temporary safe pedestrian passage built between the railway loading and unloading oil trestle bridge and the tank car, and between the automobile oil - dispensing platform and the tank truck. It serves as a cross - boundary bridge, providing a shortcut and convenience for loading and unloading workers to commute for operations, much like how a loading arm movable ladder functions in relevant oil - handling scenarios.
Movable ladder, which can be categorized as a type of loading arm movable ladder variant for diverse usage needs, has three - step, four - step and five - step types. These can meet the bridging of different platforms and the spacing between tank cars, just as a specialized loading arm movable ladder adapts to various oil - transfer setups. The movable ladder, similar to a well - designed loading arm movable ladder, also has a unique pedal spring locking mechanism and a chain protection mechanism. All rotating parts of the movable ladder are connected with bearings or shafts and nylon sleeves, reducing frictional resistance, so the operation is light - a feature that a high - performance loading arm movable ladder also emphasizes. The entire movable ladder, comparable to a neatly - engineered loading arm movable ladder, has an attractive appearance and is easy to install.

1.Equipped with a random balance device, it can suspend at any angle. By selecting a movable ladder of an appropriate length, it can meet the needs of different types of vehicles.
2. The movable steps always remain horizontal at any position. Anti - collision and cushioning pads are installed at the contact points between the steps and the tank car.


3. Compact structure: When in the stowed state, it occupies little space.
4. High load - bearing capacity: The maximum load - bearing capacity can reach 200 kilograms. Simple installation: It can be fixed with only 4 M16 bolts.
