Crane Description

The Port of San Diego has a Gottwald HhMK300Ee mobile harbor crane for cargo handling at the Tenth Avenue Marine Terminal.

 

Specially designed for maritime cargo handling operations, the Gottwald mobile harbor crane is a multi-purpose crane that can be used at various berths at the terminal for containers, general cargo, heavy lifts (up to 100 metric tons on the hook) and even bulk cargo. If heavy lift is greater than 100 metric tons, then lifting can be done with a second crane such as a crawler or truck/mobile crane for tandem lift to split the load.

It can handle an average of 25 containers per hour and can pick a fully loaded 40-foot container from the 13th row of a Panamax-size ship.

The crane is equipped with a Bromma 20-foot/40-foot/45-foot expandable spreader. Motorized grab buckets, provided by stevedores, may be used on the crane to handle bulk cargoes.
Rental Fees for the mobile harbor crane are described in Port of San Diego Tariff No. 1-G, Items Nos. 0738 and 0739. General descriptive information on the Gottwald HMK300E is shown in the following table.
