Theoretical weight of crane rail

Crane rails are laid on load-bearing beams or foundations, which are used as the running tracks of bridge cranes or gantry cranes. There are many specifications, which can be divided into light rails and heavy rails. It can be applied to cranes of different types and tonnages. The editor introduces the theoretical weight of the crane rail.

The commonly used rail specifications for cranes are: (1) 30kg/m, 24kg/m, 22kg/m, 18kg/m, 15kg/m, 12 kg/m, 8 kg/m. (2) Specifications: 50kg/m, 43kg/m, 38kg/m, 33kg/m (3) QU70 kg/m, QU80 kg/m, QU100 kg/m, QU120 kg/m. The above rail models are commonly used rail models.

Theoretical weight of crane rail:

Rail type (kg/m)		Dimensions (mm)				Cross-sectional area F (cm2)	Theoretical weight (kg/m)
Rail type (kg/m)		High A degree	Bottom B width	Head C width	Waist D thickness	Cross-sectional area F (cm2)	Theoretical weight (kg/m)
Light Rail	5	50	44	twenty two	4.5	6.41	5.03
	8	65	54	25	7.0	10.76	8.42
	11	80.5	66	32	7.0	14.31	11.20
	15	91	76	37	7.0	18.80	14.72
	18	90	80	40	10.0	23.07	18.06
	twenty four	107	92	51	10.9	31.24	24.46
Heavy rail	33	120	110	60	12.5	42.5	33.286
	38	134	114	68	13	49.5	38.73
	43	140	114	70	14.5	57.0	44.653
	50	152	132	70	15.5	65.8	51.514

model	Section size (mm)					Cross-sectional area (cm 2)	Theoretical weight (kg/m)

QU70	120	70	76.5	120	28	67.3	52.8
QU80	130	80	87	130	32	81.13	63.69
