Options and Accessories � INTEGRATED PULLEY HEAD AND/OR PULLEY BLOCK When a winch is used rather than a fixed hook, different solutions are required to lift the loads. Heila offers the optimal solution to its customers by integrating either a pulley head or top sheave into the last boom extension. To be able to work with both a winch and a fixed hook, Heila provides a pulley block that can be connected, when required, to the last boom extension hook connection point. As an additional option, Heila can install single line pull or multiple line pull solutions according to the customer’s needs. MISCELLANEOUS OPTIONS - Standing platform - Local control operator panel - Remote control - Operator cabin SAFETY AND OPERATION � SEA STATE SELECTOR Heila marine cranes can optionally be designed to operate in different sea states. To be able to select the type of operation for the different states, a crane is fitted with a sea state selector switch on its control panel (either at a fixed location or as wireless control unit). The sea state selector switch allows the crane to be operated safely and precisely in difficult marine conditions. � ACOUSTIC AND VISUAL ALARMS Acoustic and visual alarms can be installed on cranes to allow the crane to be operated reliably and safely. A green / yellow / red light is installed on the crane column. This shows, respectively, the 90% / 100% / 110% SWL load being experienced by the crane. In addition to the visual alarm, an acoustic alarm can be installed. Acoustic and visual alarms are mandatory for use on fully IACS certified cranes. 18
