Crane equipped with a maintenance elevator.

摘要

A maintenance elevator 40 is employed in the case of an emergency situation such as a failure of the carriage 16 or in carrying out regular maintenance and checkup operations. An operator can get on the maintenance elevator 40 brought to a stop at its lowermost position. The maintenance elevator 40 is moved upward along a post 12 and is brought to a stop at any position in which, for example, a gangway 57 formed integrally with the elevator 40 is opposed to the carriage 16. Movement of the operator between the maintenance elevator 40 and the carriage 16 can be done by utilizing the gangway 57. Transfer from the maintenance elevator to the carriage and vice versa can be always made in an easy and safe manner by using the gangway. Provision of all the gangways at the maintenance elevator side realizes weight reduction at the carriage side, good energy saving, and cost reduction. <IMAGE>
