The TwinSleeve design is unique. Both the Boom Sleeve and the Device Sleeve are height-adjustable. The maximum adjustable davit height is essential for lifting the user or casualty completely above the edge and ensuring safe retrieval, even when the confined space extends above floor level.
Ergonomic Operation
The height-adjustable Device Sleeve allows the operator to handle the devices ergonomically, regardless of body height. User-friendliness is further enhanced by the placement of all required devices on the operator’s side.
Total Concept
The TwinSleeve davit offers a wide range of height and outreach without requiring separate components. Various davit bases are available for optimal use in different deployment scenarios. A wide range of compatible devices enables numerous functionalities.
The required davit base depends on the characteristics of the installation site. For frequent use at fixed work locations, a permanent floor adapter is practical. For use at multiple or varying sites, a mobile base is recommended.
Modular TwinSleeve® Davit Bases
Several modular bases are available for the TwinSleeve davit:
- Floor Adapter: surface-mounted (galvanized or stainless steel);
- TwinSleeve Spider®: four-legged base;
- TwinSleeve HitchConnect®: hitch-mounted base, length adjustable;
- TwinSleeve CounterWeight®: base excluding counterweights;
Combination with Fall Protection, Rescue, and Evacuation Systems
Ergonomic operation of fall protection, rescue, and evacuation systems attached to the davit is crucial. The European Directive 2001/45/EC outlines mandatory combinations of such systems. All required devices are mounted on the safe (non-entry) mast side of the davit, i.e., the operator’s side.
The modular TwinSleeve davit is system-certified with HONOR STAR-series devices. This allows for safe operation at height differentials up to 450 meters (!). The davit is approved for two-person use (e.g., rescuer and casualty).
