Rail Lift , Iran

Elevator guide rails are manufactured from low-carbon steel grade Q235B or KP80 per GB/T 700 and JIS A 5505 standards. The standard profile is an inverted T-shape with dimensional accuracy of ±0.3 mm and angular tolerance of ±0.5 degrees. Rail lengths are 5 meters connectable up to 20 meters with linear weight of 10 to 45 kg per meter. Surface hardness is maintained at 130–170 Brinell HB for wear resistance and deformation prevention. Maximum permissible deviation over 5 meters is 1.2 mm with local curvature below 0.3 mm per meter. These rails undergo stress-relief heat treatment at 550°C to prevent deformation from residual stresses.

The running surface for guide shoes is cold-drawn to a surface quality of Ra 2 microns with edge radii of 2.5 mm. Rail joints use 12 mm steel plates with four to six Grade 10.9 bolts tightened to 400 Nm torque. Hot-dip galvanized coating 75 microns or 65-micron catalytic epoxy coating is provided for high-humidity environments. Bending moment capacity ranges from 15 to 70 kN·m with torsional resistance up to 900 Nm per meter. Rails are designed to withstand dynamic loads up to 200% of rated load and vertical speeds up to 12 m/s. Production complies with EN 81-20/50, ISO 7465, and GOST 51616 standards for safety and durability assurance.You can order and buy Rail Lift from Iran by contacting us through whatsaap and email.
