SCA-SDA Light Aluminum Alloy Ladders
Anchoring Ladders – SCA
Specifically designed for anchoring works. The ladders are made of light aluminum alloy with anti-slip rungs and galvanized steel suspension hooks. The ladders are supplied with a supplementary swivel hook to be placed on the conductor allowing the ladder to be used in a horizontal position. The ladders are available with triangular or trapezoidal sections.
Special models with different lengths are available upon request.
Anti-Fall Devices – SDA
Individual protective devices help prevent the operator from falling down. They are self-guided and self-locking devices running on a special rigid track and made of light aluminum alloy. Devices come with a polyamide mini energy-absorber and safety spring catch to connect it to the safety harness. The use of the safety harness is required. Devices allow for proper movement of the operator along the ladder and at the same time protect him from falling down. End stroke devices are provided in order to avoid that the anti-fall device from running away from the anchoring track. These devices comply with the 89/686/CEE European Standard related to the individual protective devices.
