WATERPROOF ELECTROMAGNETIC LIFMA™[Model LMU-UW] CATALOG
Full waterproof type joins small electromagnetic Lifma Series !

Waterproof specification


LMU-UW15

Rectifier required additionally
[Application]
Electromagnetic type lifting magnets used as a lifting section of cranes and hoists for transportation of steel materials in underwater work environment as well as outdoor work sites.

[Features]
  • These Lifmas can be used underwater up to 3 atm (equivalent to 30 m max. water depth).
  • Attracting and releasing workpieces can be controlled electrically by remote operation.
  • A rectifier is required additionally.
  • When an uninterruptible power supply is used, safety can be ensured in the event of unexpected power failure. (To study specifications, see the holding power graphs and lifting reference of Model LMU)


Working rate 50% ED (Repeating cycle of power on 5 minutes and pause 5 minutes)

※The lifting capacity is indicated by a value that is a half of the max. holding power.
※For workpieces having poor attractive conditions such as scraps and waste materials, use LM-EC2.
※For continuous operation, use the Lifma at 110 VDC or below. Note that when the thickness of steel plates to lift is 20 mm, the listed lifting capacity drops by approx. 20%.
※The height of lifting part is up to the top end of the inside diameter of the eyebolt.
※Cable 2 m is included.
