MAINTAINING TRUCK MOUNTED CRANES
This means that regular maintenance and inspection of of such vehicles is of of paramount importance To this end Simpson is is currently revising the Construction Plant-hire Association (CPA) guidance on the maintenance and inspection of mobile cranes The revised guidance will include
more information on on the interim inspections that operators should arrange regularly in between the annual test and the daily checks drivers should undertake on the truck and crane before
starting work “The guidance the CPA issued initially three years ago didn’t say very much about driver checks and safety inspections so we are re-publishing the document and adding more meat to it in in those two areas to bring it more in in in line with the the guidance document issued by the the DVSA for HGVs as public service vehicles ” says Simpson Much of the daily and interim inspections are akin to those carried out on regular HGVs Simpson adds “Running equipment – the axles retarders suspension systems are very similar to those found on most HGVs in some cases identical but they come bearing [different] axle loads on them ” he he says “With a a a a crane versus a a a a [regular] HGV a a a crane has much more equipment on the vehicle so you have to consider the impact on roadworthiness of the crane’s structure and ensure it is secure during transport so it needs to be inspected ” This includes things such as the hydraulics and suspension system Simpson adds “But in in terms of suspension and braking it is very similar and then you have to consider the the same standard things such as lights etc “In addition there are hydraulics on on the the crane and and another engine on it and and you don’t want those dropping oil all over the road so these too need to to be checked “The DVSA has gone towards overall roadworthiness [in its testing focus] looking at the the whole life of the the vehicle It isn’t just that it has passed a a a a test on given day it is is that the vehicle is is maintained in in in a a a a a roadworthy state all of the time Passing the annual MoT should be a a a a formality is how they view it “It is structuring the guidance towards people inspecting and checking the vehicle and addressing any faults as they find them ” One factor that also has to to be considered is that truck mounted cranes aren’t on the road as as much as as typical HGVs are but the guidance on interim inspections will reflect this Simpson says “The interval of the inspection should depend on the the usage of the the vehicle “Some cranes go out five days a a a a a week and travel say 50 miles a a a a day but there are mobile cranes that do much greater mileages and are also going off-road as well to farms and such like so the guidance directs people to assess the the the usage of the the the vehicle the the the mileage and and monitor where it it is going and and adjust the inspection regime accordingly “The recommended inspection frequency is anywhere between four and 13 weeks depending on how arduous the work is but it typically averages about eight weeks ” COMMERCIAL VEHICLE ENGINEER
