Friday roundup: Outrigger safety, AT innovation and Maxim milestones
17 July 2025
Ground pressure, green machines and a career built at Maxim. Here’s what you may have missed this week:
The ASME P30.1-2024 standard and OSHA regulations provide a clear framework of ground stabilization measures that must be implemented.
Improper outrigger use is behind 54 per cent of crane-related incidents, highlighting just how critical ground stability is to safe lifting, according to the Crane Inspection & Certification Bureau in the USA. OSHA places ground condition responsibility on the controlling entity (CE), but in practice, clear communication between CEs and crane providers is often missing.
Industry experts now recommend crane providers establish and communicate a minimum ground bearing capacity in bids, quotes, and job tickets. By accurately calculating outrigger reaction forces and matching them with supporting materials, companies can better protect workers and equipment.
As discussed in this recent feature with Kris Koberg at DICA, ground bearing capacity isn’t just a technical detail, it’s a critical safety issue that requires shared responsibility, transparency and proactive planning.
All terrain cranes are evolving fast, and it’s not just about size anymore. From extended booms and impressive load capacities to hybrid and fully electric options, these cranes are redefining what’s possible on modern job sites.
As part of a major engineering works projects, Southern Cranes and Access’ two Grove GMK5150XL all terrain cranes completed a tandem lift to install a 22 tonne substation at the UK’s London Gatwick Airport.
Manufacturers like Link-Belt, Liebherr, Tadano and Manitowoc’s Grove are introducing cranes that blend high-speed road travel with off-road performance, offering improved reach and sustainable power options. Highlights include Liebherr’s LTM 1150-5.4E with both diesel and electric drives for zero-emission operation, Tadano’s new 250-tonne crane with a 79-metre boom designed for tight urban spaces and Link-Belt’s 225|AT with smart features and HVO-compatible engines.
Fleet owners across Europe are expanding with these advanced models. In the UK, two Grove GMK5150XL cranes recently worked together to install a 22-tonne substation at London Gatwick Airport, all under strict height restrictions to avoid flight disruptions.
While it’s rare to find someone who has dedicated their entire career to one company, Larry Lis has done just that. Since joining Maxim Crane Works in 1999, Lis has grown from a sales representative to his current role as Chief Operations Officer.

Under his leadership, Maxim has remained North America’s largest crane-owning company for two decades. The company is in the midst of a major transformation — a long-term fleet refresh strategy paired with technology and operational upgrades aimed at setting the stage for sustainable growth.
“Our transformation isn’t just about new cranes,” said Lis. “It’s about building a foundation for the future through safety, technology and a unified national team.”
Maxim’s disciplined, data-driven approach guides everything from equipment purchases to long-term planning. With over US$800 million invested in fleet upgrades over the past four years, the company is focused on delivering reliable, turnkey solutions across building, industrial and infrastructure markets.
