Are the applications of heavy rails and crane rails the same

Heavy rail and crane rail differ significantly in their design purpose, structural parameters, and application scenarios. Selection must be based on the specific requirements of the railway line or equipment.

 

Firstly, in terms of design purpose:

 

Heavy Rail (e.g., GB 60kg, GB 75kg, or UIC60 rail) is primarily used for mainline railways, high-speed railways, and heavy-haul freight lines. Its design objective is to withstand the longitudinal and lateral impacts from high-speed or heavy-haul trains, ensuring long-term track stability and smooth train operation.

 

Classification		Height(mm)	Head (mm)	Bottom (mm)	Thick(mm)	Weight (kg/m)
Heavy Rail	38 KG/M	134	68	114	13	38.733
	43 KG/M	140	70	114	14.5	44.653
	45 KG/M	145	67	126	14.5	45.546
	50 KG/M	152	70	132	15.5	51.514
	60 KG/M	176	73	150	16.5	60.64

 

Crane Rail is specifically designed for heavy lifting equipment in ports, terminals, logistics centers, and industrial settings. It is engineered to withstand localized high pressure, wheel impact loads, and frequent reciprocating loads generated by cranes or rail-transported equipment. Its lateral force resistance and wheel-rail contact characteristics differ from those of railway rails.

 

Rail Type			SIZE(mm)							theoretical weight
			height	bottom width		head width		waist depth
Crane rail		QU70	120	120		70		28		52.8
		QU80	130	130		80		32		63.69
		QU100	150	150		100		38		88.96
		QU120	170	170		120		44		118.1

 

 

Secondly, regarding cross-sectional design and structural parameters, heavy rail features a larger cross-section with greater rail height, thicker web, and wider base to ensure high strength and fatigue resistance.

 

 

Furthermore, differences exist in the installation methods and supporting systems:

 

• Heavy rail is typically laid on concrete or timber sleepers.

 

• Crane rail is often fixed to crane sleepers or girders to ensure operational safety and track stability.
