Fall arrest device MAS SK 12 with 15 m 12 mm rope, model 31815

The MAS SK 12 fall arrest device with 15 m 12 mm rope (model 31815) is a rope-based fall arrest and retrieval system designed for controlled arrest of a falling user and for lowering or hauling during rescue or work-at-height tasks. The unit integrates a mechanical braking mechanism with a fixed-length rope lifeline to stop falls, reduce peak forces on the user, and allow for a controlled descent or retrieval when required. It is intended for use by trained personnel as part of a personal fall protection system in industrial, construction and maintenance environments.

Advantages

The device provides a compact, integrated solution combining a robust braking unit and a 15 m, 12 mm diameter rope suitable for many common access and rescue scenarios. Its rope diameter and length balance durability, handling and storage, while the braking mechanism is calibrated to limit fall arrest forces within industry-accepted ranges. The construction of the unit permits straightforward attachment to anchor points and integration with harnesses and connectors that meet applicable safety standards. The MAS SK 12 supports both arresting falls and controlled lowering or retrieval, reducing the need for separate lowering devices.

Suitable for

• Construction and scaffolding work where rope-based fall arrest is required
• Maintenance and inspection tasks on towers, chimneys or facades
• Rescue operations involving controlled lowering or hauling of a casualty
• Industrial access where a fixed-length rope lifeline is preferred

Key specifications

• Rope length: 15 metres
• Rope diameter: 12 millimetres
• Function: Fall arrest with controlled descent and retrieval capability
• Primary use: Single-user rope lifeline for fall arrest and rescue
• Compatibility: Designed for attachment to certified anchors and harness connection points

How to use

Before use, inspect the device and rope visually for signs of wear, damage or contamination and verify that connectors and the braking mechanism operate smoothly. Install the unit on a suitable, certified anchor point at an appropriate height and orientation, ensuring the rope runs freely without sharp edges or abrasion points. Connect the user’s full-body harness to the device using compatible connectors and verify all connections. During operations, monitor rope condition and device response; in the event of a fall the braking mechanism engages to stop the fall and the device permits controlled lowering or hauling as required by trained personnel.

Usage recommendations

Use the MAS SK 12 only as part of a complete fall protection system that includes a certified harness, compatible connectors and a suitable anchor rated for fall arrest. Ensure personnel are trained in fall protection, rescue and equipment inspection procedures. Do not use the device if the rope, braking components or housing show damage, excessive wear, contamination or corrosion. Follow local regulations and manufacturer maintenance intervals for inspection, testing and replacement.
