Car, train trestles and folding ladders

The steel trestle for cars and trains mainly serves the petrochemical industry such as refineries and oil depots. It is a substitute for the cement steel-concrete trestle used by the original refining and chemical enterprises. Its basic structure mainly consists of five parts: fixed inclined ladder, bridge deck, guardrail, column and canopy. It is a complete set of products designed and produced in accordance with the HG21608-96 standard of the Ministry of Chemical Industry.

Main technical features

The entire trestle is generally composed of five parts: fixed ladder, bridge deck, guardrail, column and canopy, which are detachable structures connected to each other by bolts. Pipe supports are installed under the bridge deck.

The bridge deck material is composed of channel steel, angle steel and other steel sections and G253/30/100 anti-slip grid plate, patterned steel plate, etc. The galvanized grid plate structure has the characteristics of no liquid accumulation and no snow accumulation on the surface, has good anti-corrosion performance, and the multi-diamond structure on the surface has good anti-slip performance.

The canopy is mostly in the form of a steel frame structure with glass fiber reinforced plastic tiles attached.

The surface treatment adopts shot blasting to remove rust, and is hot-dip galvanized, electroplated, and painted according to user needs.

The humanized design fully considers the convenience and safety of operators.

The design of the trestle's carrying capacity takes into account the loads of existing equipment, pipeline weight, wind load, snow load, pedestrians, etc.

The folding movable ladder produced by our company is equipped on the trestle to truly achieve safety, reliability, rust prevention, and anti-slip.

Optional additional equipment for the trestle

Fire alarm system includes fire rack

Pipe rack and reserved holes, installation holes, foundations, etc. for oil and chemical pipeline systems

Lighting racks, lighting systems, monitoring systems, lounges, operating rooms

Safety doors, oil collection barrels, cleaning pipes, and top drains installed at both ends of the trestle

Suitable for small and medium-sized oil depots, single oil types, and small daily loading and unloading quantities. Small size, small footprint, small length and width, and a single column supports the load of equipment and people on the bridge deck. This is its main feature that distinguishes it from other trestles.

One trestle serves two lanes of vehicles, and the direction of the lanes is parallel to the direction of the trestle. The length of the trestle is designed according to the number of parking spaces. The layout of the crane positions is mostly cross-distributed to make full use of the trestle space. For the situation of multiple trestle and multiple lanes, two adjacent trestle can also be used to serve one lane to reduce the vehicle scale, while maintaining and repairing without stopping production. For two-sided operation, the height of the trestle is mostly between 2.5m and 2.8m, which is its main feature that distinguishes it from other trestle.

One trestle serves multiple lanes of vehicles, and the direction of the lanes is perpendicular to the direction of the trestle. The length of the trestle is designed according to the number of parking spaces, and the crane positions are arranged on one side of the trestle. For single-sided operation, the tank truck needs to pass through the trestle, and the height of the trestle is high, which is the main feature that distinguishes it from other trestle. Train trestle special case

One trestle serves two train lanes. According to the number of train oil pipes and the spacing of the oil pipes, the length of the trestle and the number of crane positions are designed. The layout of the crane positions is mostly cross-distributed to make full use of the space of the trestle. It operates on both sides, has a longer trestles and more cranes, which are its main features that distinguish it from other trestles.
