CHAT hydraulically expanding tools save time and reduce costs during the alignment and closure of shaft couplings.

Each tool unit is located in a coupling hole and alignment is achieved as the sleeves are expanded simultaneously. The coupling faces are then closed using the tools in preparation for installing the coupling bolts.

The CHAT system is powerful but safe, highly effective, versatile and easy to handle. It can greatly improve the accuracy and effectiveness of outage planning. Moreover, should conventional coupling bolts be seized because of coupling slippage, CHAT can be used to adjust and hold coupling alignment as bolt removal is achieved.

Benefits include:

• Time saving
• Cost reduction
• Aligns and closes couplings
• Accurate and reliable
• Quick and efficient
• Versatile
• Powerful and safe
• Easy to handle
