Liftech Consultants Inc.

Articulated Cranes

Liftech Consultants Inc. has provided structural engineering services since 1964. McKay International Engineers merged into Liftech in 2022 and has provided mechanical and electrical engineering services since 1969.  

Our experience includes the design of cranes, wharves, floats, buildings, heavy lift systems, and other specialized systems.

We have special expertise in the design of container handling cranes and other custom heavy equipment, including design of dynamically loaded steel structures, high duty cycle winch and rail machinery, and mobile heavy equipment power, control, and automation systems. We also provide professional engineering design of structural, mechanical, and electrical infrastructure for terminals and other maritime facilities.

We routinely work with a wide variety of specialized cranes, container handling equipment, bulk material handling equipment, and custom special heavy equipment. This includes ship-to-shore (STS) container cranes, rail mounted gantry (RMG) cranes, automated stacking cranes (ASC), rubber tire gantry (RTG) cranes, ship loaders, ship unloaders, stackers and reclaimers, mobile yard equipment, and automated horizontal transport systems. 

Our approach to projects and experience with cranes and other unusual systems allows us to produce creative and practical solutions to unusual problems, tailored to the specific needs of our clients. Collaboration among our engineering staff and with our clients ensures our designs are reliable, functional, efficient, environmentally sound, and cost effective over the entire life of the system.

We are experts in structural design, fracture mechanics, structural maintenance, and fatigue crack control. Our experience includes the design of structures made of steel, reinforced and prestressed concrete, masonry, and wood.  

Our designs include unique solutions. For example, we invented “banded prestressed concrete,” which has become the industry standard for prestressed concrete slabs. We also invented the low profile and articulating boom container crane designs for STS crane operation in areas with height restrictions.

We work with national and international clients including owners, engineers, operators, manufacturers, architects, and riggers. Our clients include port authorities, shipping companies, terminal operators, crane manufacturers, construction companies, government agencies, and crane maintenance companies.
