Technical data | User instructions

Application:
This mechanical load cell has been designed to provide a trip point in lifting systems which have a dead end wire rope. The trip point provides a signal that the user may employ depending on his requirements.

• for load limiting in lifting systems
• to limit the speed as a function of the load on traversing
• to limit the effort applied for pulling

This load cell is preferable for lifting applications and where it is essential to minimise the lost headroom.

Operating principle:
The load cell operates by the movement of metal within its elastic limit. This movement acts on an adjustable high
precision microswitch, giving an "all-or-nothing" signal. Movement is limited by the contact of parts 1 and 2.

Associated equipment:
The HF05 mechanical load cells are normally used in conjunction with the HF85/1 monitor, but may also be
used with a PLC or a simple automatic relay.
