The HSM-17 is the second generation switch machine from the ARS engineering team. This machine was developed to replace present hump machine applications or where a quick throwing machine is required. The HSM-17 also requires minimal to no maintenance and comes in a 12VDC with battery or 120-volt DC version. The HSM-17 is a game changer with a throw time of 0.50 seconds, and 4,000 lbs. of throw force, the machine can handle longer or welded heal block points and is more durable than other units in this space. The HSM-17 has the same key features as the YM-16, such as simple design, minimal to no maintenance requirement, high reliability and durability and can be installed in any environment, including temperatures ranging from -40ºF to over 185ºF. The HSM-17 is trailable without damage and has the broken rod detection reducing the risk of derailment and machine downtime.
