Straight Telescopic Boom Mobile Harbour Crane Hydraulic Marine Boat Ship Crane
Marine cranes are also called cranes, wharf cranes, port cranes, deck cranes, shore cranes, ship cranes, cargo cranes, etc. It is a kind of crane and a deck machinery on a ship. A kind of equipment for loading and unloading cargo on ships, hydraulic crane is a kind of loading and unloading equipment commonly used on ships.
Product Component
Boom installation
It is composed of boom, lifting column (or lifting mast), rigging and winch (or crane). The boom device is the traditional lifting equipment on the ship. Although there are many ropes and troublesome operation, it has been widely used because of its simple structure, easy manufacture and low cost.
Single lever operation and double lever operation
Loading and unloading cargo with a boom device, there are two modes of single-rod operation and double-rod operation. Single-rod operation is to use a boom to load and unload cargo. After the boom lifts the cargo, pull the guy rope to make the cargo swing outboard or the cargo hatch together with the boom, then put down the cargo, and then turn the boom back to the original position. bit, so back and forth. When loading and unloading, the suspension rod must be swung with a drag cable every time, so the efficiency is low and the labor intensity is high. Two booms are used for double-rod operation, one is placed in the sky above the cargo hatch, and the other is extended outboard, and the two booms are fixed on a certain working position with a lanyard. The hoisting ropes of the two suspenders are connected together on a suspension hook. As long as two cargo cables are collected and released separately, the goods can be unloaded from the ship to the dock, or loaded from the dock to the ship. The loading and unloading efficiency of the double-lever operation is higher than that of the single-lever operation, and the labor intensity is also lighter.
Double Jacks Boom Mount and Ebel Boom Mount
Improved boom installations came later. The double jacking rope boom installation is improved from the single rod operation boom installation, in which there are only lifting ropes and two sets of left and right separated jacking ropes. The boom is controlled by one lifting winch and two jacking winches, which is easy to operate and has high loading and unloading efficiency. The Ebel boom rig is a modification of the twin-rod operated boom rig which includes a cargo winch, jack and drag winches. The boom can be quickly placed in any position with the help of a winch. At the same time, it can also lift and drop goods at fixed points within the working radius of the boom to improve loading and unloading efficiency. This is an important step forward towards fully automated cargo handling.
