The next step in the evolution of design

Our latest evolution of polar cranes utilizes a multipurpose design that maximizes operational capability by combining numerous lifting features into a single compact and weight-efficient trolley. The design improves productivity and reliability by providing four primary lifting systems including a main hoist, auxiliary hoist, maintenance jib crane, and containment inspection man lift, all conveniently located on one trolley.

The polar crane main and auxiliary hoists are designed to perform typical plant maintenance and operational functions, and both hoists can be provided with a single failure proof or non-single failure proof design.

To facilitate multipurpose lifting, a maintenance jib crane is typically mounted on the main trolley, designed to provide lifting capability during maintenance operations of the entire polar crane. This reduces the need for cumbersome lifting equipment that is typically provided by the customer’s plant on a temporary basis to complete polar crane maintenance.

An additional feature of the multipurpose polar crane design is the containment dome inspection and maintenance station. This cleverly designed device utilizes a telescoping lifting device, which is installed on the multipurpose trolley to provide a safer, simplified and cost effective method for inspecting and maintaining the containment dome.
