Tractel DynaSafe Mecha Mechanical Load Limiter, Rope Dia. Range Options from 5mm to 35mm

This mechanical load cell has been designed to provide a trip point for lifting systems which have a dead end wire rope.

Model: 

TDMM-5202


  • Simple and economical solution for load limitation.
  • Easy installation on the lifting cable.
  • Capacity 3.2t, 6t or 12t.
  • Protection class: IP63.
  • Operating temperature: -30 to +80 °C.
  • In conformity with 2006/42/CE.
  • With connector and 2m cable.
  • Mechanically adjustable.
  • Automatic reset if wire rope unloaded.
  • Mecha 3.2 - for load capacity from 200 daN to 3200 daN at the wire (5-16mm)
  • Mecha 7 - for load capacity from 500 daN to 7000 daN at the wire (17-26mm)
  • Mecha 12 - for load capacity from 1000 daN to 12000 daN at the wire (24-35mm)

The Dynasafe Mecha 3.2, 7 and 12 are robust and affordable mechanical limiter, designed to manage one or two safety thresholds on elevating equipment.

The deflection of the wire rope exerted by the load limiter produces a tangential force which is proportional to the force exerted on the wire rope when pulled. The deformation of the load limiter body then causes the micro switches integrated in the load limiter to inverted position and give an “all-or-nothing” signal.
