UNISON RESTRAINED SPRING MOUNTS (RSM)

█ SPECIFICATION

For the equipment with weight variations between operating and installed weight such as boilers, refrigeration machines etc, and outdoor equipment such as cooling towers exposed to wind load, spring isolators can be used but for the prevention of spring extension due to weight removal, a housing having vertical limit stops shall be provided. The housing shall act as blocking during installation. A minimum 0.5”(12mm) clearance around restrain bolts and between the housing and the spring shall be maintained for not interfering the spring movement. During normal operation the limit stops shall be free from contact,. Hot dipped galvanized unit shall be supplied for outdoor installation UNISON Engineering Co., Ltd. Manufactures the type RSM for the mountings.

█ MOUNTINGS

Type RSM restrained spring isolators have hold-down bolts to limit vertical(upward) movement when loaded weight is temporarily removed and provide safety stops when lateral movement might be happened due to windy roof top installation. The rigid sides act as non-yielding blocks and support the equipment at elevation before spring adjustment which can be accomplished by inserting shims between the top plate and the flat shims are removed after spring Adjustment so maintain operating gap without changing the mounting height.

█ DESIGN CONDITION

RSM spring mountings are covered with hot dipped galvanized paint for oxidization prevention in outdoor installation. RSM spring mountings are specially designed to withstand high levels of Vibration and shock and to protect equipment from impact shock, The role of RSM spring mountings. Is to serve as blocking during erection and to prevent spring extension when weight is removed. RSM spring mounting are particularly suitable for heavy stamping machines such as cooling tower.
