1 General
1.1 Description
The hoist-monitoring unit is an electronic device designed to supervise and protect the hoist. The hoist-
monitoring unit measures the use of the hoists and prevents hoisting or lowering in case a situation is
detected which can cause a potential dangerous situation. The hoist-monitoring unit records the use of
the hoist and calculates the remaining Safe Working Period “SWP” according to the FEM and ISO
standards.
The hoist-monitoring unit is designed to fit a wide variety of hoists and motor drives. It can be used with
variable speed control drives, as well as two speed drives. The hoist-monitoring unit contains tailored
hardware and software, especially designed for crane use.
With the display, the unit can be programmed and calibrated, and stored values can be read. The hoist-
monitoring unit can be equipped and installed with many different options and additional features such
as:
•
continuous load display
• tandem operation (up to five units)
• service-warning information
• hook levelling
• intermediate overload options
A service agent authorised by the manufacturer can provide detailed information and professional advice
on a tailored solution for each application.
The hoist-monitoring unit is a safety device, installed by the manufacturer. Only service
personnel authorised by the manufacturer are allowed to program and calibrate the unit.
Faulty programmed or calibrated unit may cause malfunctions that results in dangerous
situations.
Under no circumstances it is allowed to by-pass or remove the hoist-monitoring unit, as that
would disable all supervision and safety features.
