Daily Maintenance of Rubber Fender
Dec 19, 2018


Maintenance of rubber fenders at wharfs requires shutdown to varying degrees. Fast-paced loading and unloading terminals are not allowed to stop production and repair for a long time. To properly solve this contradiction, we can proceed from the following three aspects:

1. Seize the gap between the barge and the berth and the time of tide fluctuation, and repair the barge by inserting needles into the seam. This method is suitable for small-scale maintenance tasks with little workload. Generally, the maintenance team of the loading and unloading company carries out the construction, which can not be restricted by the contractual period of outsourcing, neither affecting the production, but also flexibly grasping the construction in batches and blocks. From the perspective of economic benefits, it can be compared with outsourcing cost savings. For example, the installation of M(DA) fender in the second berth of Nanzhan wharf, the maintenance team of the company cooperates with the fittings workshop. Firstly, the fittings and brackets are processed and arranged on shore. Then, according to the gap time of the front production, the installation is completed in batches. The total material cost of installation is 11,000 yuan (excluding D-type maintenance). The cost of manual materials is 26,000 yuan for the purchase of shipboard itself, such as consignment of outsourced installation.

2. For maintenance tasks with large workload, complex construction and long period, such as the manufacture and installation of steel-rubber mixing fender in Laobidu berth, it is generally advisable to outsource. Because this kind of daily production and installation technology is used together, it takes a long time to vacate the berth of the wharf. With this method, the company's planning and production dispatching department must be carefully studied and arranged, according to the production capacity and production tasks of the company's various terminals, overall coordination and balance, partial and regular shutdown.

3. Strengthen inspection and maintenance

The most basic measure of maintenance work is to pay attention to the inspection and maintenance in peacetime. Whether this work is implemented or not is very important to reduce maintenance. The company's wharfs should set up a special person responsibility system to strengthen the inspection and maintenance of the rubber fender in the responsible area, so as to find out some minor faults of the fender in time, such as loosening of fastening screw, damage of bracket parts, and so on, so as to maintain it immediately and prevent the development of rubber fender and mooring pillar damage. Small holes are not repaired, big holes bear hardships, a large number of fender damage in the past, falling off and not timely inspection and maintenance is very relevant. With the continuous progress of the professional technology of rubber fender in wharf, the market of rubber fender in Wharf will be more suitable for fast-paced loading and unloading production wharf fender. Therefore, the problem of type selection will continue. Similarly, with the change of the type of fender used and the management system of enterprises, different maintenance and management methods should be adopted to improve the maintenance quality and level of the rubber fender.

Vulcanization process of rubber fender

A. Rubber fenders are mainly vulcanized from mixtures of natural rubber and synthetic rubber.

B. Additives such as carbon black and anti-aging agent are added to rubber fender to enhance its physical and mechanical properties, seawater corrosion resistance, anti-aging and ozone resistance.

C, the compound is uniform, and there are no impurities (foreign impurities), bubbles, darkness, cracks and other defects that hinder product quality.

D. During vulcanization, the skeleton plate is firmly bonded with rubber, and no steel plate is exposed.
