Draft Lugs

This item is a special cast steel component for the end of the bottom frame of a railway freight car. It is made of ZG230-450 cast steel and is formed as a single piece. The product is equipped with six long elliptical adjusting sliding grooves, which enable adjustable installation positions and can be adapted to different assembly spacings. Between the grooves, a reinforcing rib structure is set up, which has good shock resistance and fatigue resistance and can withstand the traction load of the vehicle as well as the forces during hoisting, rescue and re-railing. The casting body is engraved with the part number and factory logo for easy maintenance identification and traceability. It is widely used in new manufacturing and segment repair scenarios of railway freight cars, and is suitable for various types of freight vehicles such as open wagons and tank cars. It is a key auxiliary load-bearing component for the traction connection and hoisting operations of the vehicle body.

Product Description

Product Advantage

1.Integral cast‑steel construction Made of ZG230‑450 railway‑grade cast steel, no welded joints. High integral strength with excellent impact‑resistance to withstand vibration, traction and lifting loads.

2.6‑slot adjustable structure for high assembly adaptability Six long‑oval slotted holes compensate assembly deviation and allow position adjustment, simplifying on‑site installation and maintenance replacement.

3.Reinforcing‑rib reinforced design for great anti‑fatigue performance Built‑in thick reinforcing ribs distribute stress effectively to prevent cracking under load and extend service life for long‑term wagon operation.

4.Built‑in casting marks for easy traceability Part number and manufacturer logo are cast directly on the body, convenient for inspection, stock‑taking and component traceability in railway workshops.

5.Rigorous casting quality control Sand‑blasted surface treatment. Magnetic particle inspection is available for critical load‑bearing areas. Anti‑corrosion painting can be supplied as required.

6.Wide compatibility for multiple wagon types Interchangeable for open wagons, tank wagons and other freight cars, suitable for new‑building, workshop and depot maintenance.

Product Uses

1.Lifting point for hoisting
Serves as load‑bearing lifting fulcrum for integral wagon hoisting and transportation during manufacturing and overhaul.

2.Derailment recovery lifting point
Used for hoisting in derailment accident rescue, cooperating with rescue equipment to realize wagon rerailing.

3.Adjustable assembly connection
Long‑oval slotted holes compensate assembly deviation, adjust bolt mounting position and facilitate parts replacement.

4.Auxiliary mounting base
Acts as mounting base for end‑body accessories, widely used in new‑building, workshop and depot maintenance of open wagons, tank wagons and other freight cars.
5.Auxiliary traction force transmission
Mounted on the end of wagon underframe, transferring partial traction load and sharing end‑part stress during vehicle operation.

Product Operate Guide

Check the draft lug (059‑37‑469 R2) before installation. Ensure no cracks, deformation, sand holes or burrs on the surface and slotted holes.Mount the plate on the wagon underframe end. Adjust position freely through six oval slots to match assembly tolerance. Fasten bolts diagonally with standard torque to ensure firm fitting.This part is used for auxiliary traction, vehicle lifting and derailment recovery. Overload lifting and eccentric force are strictly prohibited.Regular visual inspection is required. Replace the component immediately if damaged, deformed or severely worn. Welding repair is not allowed.Store in dry and ventilated conditions. Keep away from moisture, rust and violent collision.
