bar pressure), with additional spark protection also being avail- able, ensuring explosion protection. Te JDN big-bag handling hoists are designed with twin


overhead trolleys connected with rigid spacer beams, and the whole unit running on an overhead support beam. Te hoists are designed for continual 24/7 operation within extreme low headroom conditions. Te hoists are available in two configura- tions with either single or twin lift/load hooks. Te single hook unit is designed for operation with a standard cruciform lifting beam. Te twin load hook models operate with more complex beam designs or for standard lifting beams featuring twin suspension points. Tey can also be operated with synchronized lifting operation. Each hoist is fitted with a chain box that is sited to eliminate the risk of collisions between loads and the chain box. Te low headroom designs are also compatible with the handling of a wide variety of bulky or unusual loads. Tese big-bag hoists have 100% duty ratings to minimize downtime. Tey can also be supplied with a wide variety of beam sizes and profiles, with optional hook centres located as required. Te compact design incorporates many JDN standard


components to guarantee reliable operation combined with cost effective manufacture. No additional motor lubrication is required and only a small number of wear-free moving parts are incorporated so maintenance is minimized. ■

New Version of Simulation Software Set for Release ١Նذ即件软拟模版新


Flow Science Inc., Sante Fe, New Mexico, U.S., announced the released a new version of FLOW-3D Cast, its software specially designed for metalcast- ers. FLOW-3D Cast v4.1 offers powerful advances in modeling capabilities, accuracy and performance. Active Simulation Control, one of the software’s


new features, gives users the ability to control time- dependent events. For example, the transition to the fast shot stage during high pressure diecasting can be synchronized with metal arriving at the in-gates. Diecasting users will also benefit from the addition of a squeeze pin model, a faster and more accurate thermal die cycling model, and the ability to use a P-Q2 diagram to realistically control the motion of the shot sleeve plunger. Two other featured enhance- ments include the automation of post-processing and report generation. With batch post-processing, users can request their results ahead of time and then gener- ate HTML-based reports that can be easily shared to communicate results and analyses. Other key models and improvements include:


• Improved runtimes and solver optimization. • Cavitation model. • Extensions to the air entrainment model. • Enhanced cooling channels. • Valves and vents. • Intensification pressure model. • Quick calculators. ■
