Specialized Equipment Design

Since its inception, 2DM Associates has been engaged in the design of unique specialized lifting equipment. As equipment of this nature is generally not governed by specific industry standards or codes, a broad depth of experience is needed to first establish logical design requirements in order to produce a safe, reliable, and practical design.

Integrated Lifting Equipment

Rigging and lifting work performed in the tight confines of industrial facilities can often benefit by using parts of existing structures as part of the lifting equipment. Often more than simply supporting lifting gear on an existing structure, 2DM Associates has designed installations where the existing structure becomes part of the lifting system.
