(54) Cover


(57) Concrete mixer vehicles (100) having a recessed man-access way (114) in mixer drums are known. Preferably such man-access ways (114) have a closure (118) within the profile of the drum (102). A continuing problem in that the closure (118) may still be a safety hazard as the drum (102) rotates.
A cover (124) for such a man-access way (114) is disclosed. The cover (124) may be made of a plastics, a composite or a metal. It may have engagement means (142,144;128) cooperating with corresponding portions on the man-access way or may be secured by the inherent resilience of the material. A handle (126) may be provided and may be removable.
