Construction machinery sunroofs
Construction machinery sunroofs are typically made of tempered glass 8 to 12 millimeters thick, with corrosion-resistant steel or aluminum frames. Standard dimensions range from 500×500 to 1200×1000 millimeters, with wind pressure resistance up to 1200 Pascal and ambient temperature tolerance up to 80°C. The opening and closing system uses a 12 or 24-volt electric motor with worm gear and movement speed of 5 to 10 millimeters per second.
The mechanism includes steel rails and rollers with nickel coating and initial lubrication for smooth, wear-free operation. EPDM sealing prevents dust and water ingress into the cabin, with a service life of over 50,000 open-close cycles. Sunroof design complies with ISO 12100 and construction machinery safety standards.
