and feature twin overhead trolleys connected with rigid spacer beams, and the whole unit running on an overhead support beam. Te hoists are dust-proof and explosion pro- tected, designed for full 24/7 operation within extreme low headroom conditions. Individual handling capacities 1,100 and 2,200kg are available in two configurations of either sin- gle 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 suspen- sion points. Tey can also be operated with synchronized lifting operation. Each hoist is fitted with a chain box, which is sited to eliminate the risk of collisions between loads and the chain box. Te hoist 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, so eliminating downtimes. Tey can also be supplied with a wide variety of beam sizes and profiles, with optional hook centres located as required.
