A spreader beam (40) for lifting a load, the spreader beam comprising: at least two load points (52), each load point being arranged to support a respective portion of the load; load detection means (64) arranged to output a signal indicative of the magnitude of individual loads applied to each of the load points when the load is supported; and slope detection means (62) arranged to output a signal indicative of an inclination of the spreader beam relative to a horizontal plane. |
