BODY

Models LLL18 LLL28, LLL45, LLL60, LLL80, LLL150 and LLL200:

Cast from high-grade LM4 aluminum with high proof and tensile strength with excellent machining properties.

 

DISC SPRINGS

To German standards DIN2093 and 2092. This allows for repeatability of set point within I%.

 

DIMENSIONS

A compact load cell that when fitted does not affect the height of lift.

 

GUIDES

Cast from LM4 aluminum. Guides provide a higher degree of accuracy due to the increased contact surface between the guides and the crane/hoist rope.

 

LIMIT SWITCH

A heavy-duty microswitch manufactured to EC specifications able to work up to 220 volts AC

 

 

PAINTING SPECIFICATION

Anti-corrosion cleaned to remove surface scale, powder coated, and electrostatically applied to a dft. of 50-75 microns, oven post-cured at 200°C for 20 minutes.

 

IMPORTANT NOTE:

Below are rope loads for use on class 1 & 2 factory duty cranes used in accordance with BSS 466 of 1984, M5 rating. Consult factory for class 3 & 4 heavy-duty applications.
