KNUCKLEBOOMS Ӏ SECTOR REPORT
opposed to hydraulics powered from the truck’s diesel engine, is also making inroads, as are other emissions-saving technologies. Danish knuckleboom makers HMF have gone perhaps furthest along this road, fitting their electric- powered loader crane to a truck which is itself powered by biogas rather than diesel. Danish builders' merchant
Bygma came up with the idea and are operating what they say is a first in the industry.
CO2 SAVINGS HMF’s
electric-powered knuckleboom on a biogas truck
For the past 15 years, Bygma has been using HMF cranes, which means, given the size of the company’s fleet, that hundreds of Bygma trucks are driving around with a red HMF crane fitted to help with the unloading of all kinds of building materials. According to Bygma's purchasing director, Preben Nielsen, the investment is an important part of the company's goal to reduce CO2
emissions from its own
operations. "A biogas truck contributes significantly to CO2
reduction; in
fact, as much as 90% compared to diesel depending on the type of gas used. That's why we made this investment," he says. "Bygma's new trucks will run on biogas, which offers the greatest savings on CO2
. As the truck is
stationary while work is being carried out with the crane - which is often used many times a day - we think it’s obvious to combine the two technologies." An electric or biogas truck
may be more expensive but there are advantages to switching to the greener technology: "The electric HMF crane is almost completely silent, and since the truck doesn’t emit CO2
when it
is switched off, we significantly reduce both emissions and engine noise. The new trucks therefore offer a significant noise reduction compared to traditional trucks, which is very important in connection with construction sites in urban areas." "We’ve been using HMF cranes
for about 15 years, so it goes without saying that we’re satisfied with them," he says. “Our drivers are pleased with the crane's extra 'bend in the back' which makes it flexible to work with. Our close cooperation with the company is also crucial, and the reason for us to continue our work with HMF. “The construction industry of the future is undoubtedly green. We support the Danish government's goal of reducing greenhouse gas emissions by 70% by 2030. That's also why we're investing in these biogas trucks. We consider ourselves pioneers in this field and look forward to gaining some experience with our new biogas and electric-powered trucks before deciding on the next step." All Bygma's forklift trucks
are already electrically powered, and the distribution trucks are currently being replaced by electric versions.
