Crane Services

Crane Design

We have designed cranes for most of the world’s container crane manufacturers. For Paceco, we developed the original standard A-frame, modified A-frame, low profile quay cranes, and RTG frame structures that have become the industry standard. For Mitsubishi, we provided structural design for the first machinery-on-trolley cranes to meet the strict stiffness criteria of the Port of Singapore Authority. For Paceco, Italimpianti, and Samsung, we designed the then largest low profile cranes. We provided designs of the articulated booms for all of the quay cranes in Kaohsiung, Taiwan. Most recently, we designed one of the largest container cranes with a 100 ton capacity and have reviewed many of the manufactured DHT40 (dual hoist tandem 40) cranes.

 

We design modifications to increase the lift height, extend the outreach, increase the capacity, and to change the rail gage. We design jacking systems used to raise cranes that dramatically decrease the out-of-service time for the crane.

 

In addition to container cranes, we have worked on the designs of the world’s largest land and water based cranes. See our Heavy Lift page.

Crane Procurement

We provide crane procurement assistance to port authorities, shipping lines, and terminal operators. Our services range from preparing specifications to complete assistance, including bid evaluation, design review, quality assurance audits, and fabrication inspection. We write specifications to assist in the procurement of hundreds of container cranes, most of which are super post-Panamax.

Crane Repair & Maintenance

We are often called upon for consultations on damaged cranes. Our repair services include assessment of the situation, design of temporary securing, design of repairs, and oversight of the repair work. The repairs often involve replacing members, strengthening local areas, and heat straightening.

 

We help clients with crane equipment assessment and recommendations for purchase, modification, or repair. Our services include useful life assessment, reliability studies, condition surveys, and inspection programs. We are occasionally retained as an expert witness to assess crane accidents, evaluate repair estimates, and help resolve disputes.

Crane Relocation

We provide engineering for the transportation of cranes, oil processing modules, offshore oil structure components, and miscellaneous equipment on barges and ships. Our services include reviewing the structures and the vessels for voyage forces, designing required reinforcing for the structure and/or vessel, and designing the attachments to the vessel. We design crane move systems that lift and move cranes with little out-of-service time for the crane.
