Loading and unloading method of container loaded logs

Abstract

The invention provides a method for loading and unloading container shipped logs. The method comprises the following steps: performing preparation before operation; disassembling a container by dragging a steel wire rope under the command of professional staff, opening a door of the container, stretching the teeth of a forklift into a gap below a selected log by 500-1,000mm, lifting one side, close to the door of the container, of the log by 50-150mm, padding a wood partition, inserting two ends of the steel wire rope from recesses in the wall of the container, hooking out the steel wire rope from the bottom of the container by using a long-handle iron hook, locking the steel wire rope, and hanging one end of the locked steel wire rope to a hanging hook of a clamp of a loading machine; completely dragging the bundled log out of the container; untying the steel wire rope bundling the log by a loader, shoveling the log by the loading machine, and placing and stacking the log. The method has the effects that the efficiency is improved by 60-70 percent compared with the prior art, the using quantity of mechanical equipment is reduced by 30 percent, the manpower is reduced by 30 percent, and the energy consumption is reduced by about 50 percent.

Description

technical field [0001] The invention relates to a loading and unloading method for shipping logs in a container. Background technique [0002] Restricted by the properties of the logs, the early shipping methods of logs were mostly shipped in bulk. With the rapid development of containerization, some logs have recently begun to be shipped in containers. For this new type of freight transportation, at this stage, various ports and logistics companies do not have mature and perfect production processes. Due to the obstruction of the container wall, the unpacking operation can only be carried out from the side of the door; and because the logs in the box are squeezed against each other, the friction between the logs is relatively large. The current unpacking operation for container shipping logs is to bind a single log to the shovel teeth of a forklift with ropes or iron chains, and then drag it out of the box after lifting the shovel teeth. The single-box operation takes a lo...

Due to the obstruction of the container wall, the unpacking operation can only be carried out from the side of the box door; and because the logs in the box are squeezed against each other, the friction between the logs is relatively large

The current unpacking operation for loading logs in containers is to tie a single log to the shovel teeth of a forklift with ropes or iron chains, lift the shovel teeth, and drag it out of the box. The operation of a single box takes a long time, is inefficient and consumes high energy consumption.
