Liebherr has delivered four new mobile construction cranes to BKL Baukran Logistik GmbH. Two MK 88-4.1 and two MK 140 have joined the company’s fleet at its Munich, Rosenheim, and Frankfurt am Main locations. BKL now has four more aces up its sleeve for customers when it comes to short jobs involving projecting edges and space restrictions.
“With more than 600 tower and mobile cranes available, BKL offers its customers a huge selection of different machines. It’s important that our team is trained and has experience in handling this range so that we can get the best use out of each crane,” says CEO Jörg Hegestweiler. “So, one of the decisive factors for buying the mobile construction cranes from Liebherr was their easy handling, which is similar to that of the LTM series cranes we provide for mobile work.”
Experienced MK customer
Crane specialists at BKL have been successfully working with machines from Liebherr’s MK series and its time-tested taxi crane concept for over 20 years. Only one person is needed for travel, assembly and operation. Additional transport vehicles aren’t required. These features even make jobs with short downtimes cost-effective and are a particular advantage given the current shortage of skilled workers. Mobile construction cranes offer long reaches, have a compact footprint, and can be positioned close to buildings.
Typical tasks for the MKs, which BKL deploys across Germany, include green roof installations, steel construction work, flat roof renovations, and roof replacements. The crane rental company’s mobile construction cranes often play unusual roles when customers need crane solutions for special lifting projects. An MK 140, for example, suspended a grand piano complete with pianist as part of an open-air concert. Another MK 140 played a leading role behind the scenes of a new BKL video by moving the lighting and handling HSE-Equipment.
Electric operation without emissions
The four-axle MK 88-4.1 offers a hook height of up to approx. 59 metres (45-degree luffed position) and a maximum radius of 45 metres. It has an eight-tonne load capacity and can still lift as much as 2,200 kilograms at its jib head. Powered by site electricity or another power source, the MK 88-4.1 works without CO2 emissions and is exceptionally quiet on site. This can prove a particular advantage on night-time construction sites. And its hybrid power concept means that operation isn’t limited to one source of power: if an external supply isn’t available, an efficient diesel generator ensures self-sufficient operation.
Long reach
The five-axle MK 140 has a maximum lifting capacity of eight tonnes and a jib head lifting capacity of 1,900 kilograms at a 58.5-metre radius. So it offers the perfect solution for when heavy lifting and long reaches are required. The MK 140 is the only machine in the MK series with a three-section telescopic tower of solid wall construction. It also features an infinitely height-adjustable lift cabin, as do the other cranes in the series. The crane operator is able to work efficiently inside thanks to large glass panels, an ergonomic and comfortable control stand, and modern display systems.
