Made in Japan
Manufacturer : Satuma
Model : BMS5-T, BMS5-WT

The MEW Lifter brake uses a MEW Lifter (trade name of an electro-hydraulic lifter) instead of the electromagnet used by an electromagnetic brake. The MEW Lifter characteristics mean a slower operation with less impact than electromagnetic brakes. To further decrease the operational speed, type BMS5- WT decreases the braking torque, and uses a MEW Lifter equipped with a lowering time-adjustment mechanism, which is ideal for traversing and traveling of cranes and stopping of conveyers.

Feature

1. A brake lining with a contact angle of 60° is adopted.

・Excellent initial braking torque characteristics and easy replacement

2. Automatic vertical gap adjustment of brake lining

・Simple maintenance and inspection

3. Can be manually opened

・This no-voltage actuation bake can be manually opened using a special auxiliary nut (bolt.)

4. Large electromagnetic brakes come with an air damper (which can be optionally mounted to other electromagnetic brakes. Please refer to the note column of each specification/external dimension table for the standard equipment scope.)

・Mounting the air damper helps ensure shockless and low-noise operation

Specifications and external dimensions of BMS5-WT Type MEW Lifter brakes

Note 1: See Table 1 (P.1 and 2) for major ratings.

Note 2: Shared use for 200 V and 400 V is possible by changing the connection of the MEW Lifter, but shared use for 50- and 60-Hz frequencies is not allowed.

Note 3: MLD-15HS (used for BMS5-1316T) is exclusive for each voltage and frequency.

Note 4: The moment of inertia and each braking workload of the brake drum for BMS5-5276 (W)T are for your reference.

Note 5: Contact us when using the brake for crane hoisting. Some brakes are not appropriate for this purpose.
