Provision & Ammunition Hoist (RMN)

A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium. The most familiar form is an elevator, the car of which is raised and lowered by a hoist
mechanism. Most hoists couple to their loads using a lifting hook. MH Integrated System Sdn Bhd offers a low cost solution to the RMN. As we are all aware many of RMN vessels lacked proper capabilities against air and even surface threats. Most of the ships are equipped with unguided 40mm, 57mm and even 76 mm guns, which are aimed locally; the old spray and pray method. Even the Kedah class, built to the fitted for but not equipped concept, have yet to be fitted with its anti-aircraft missile system.

Hoist Control & PLC Programming

The control strategy for hoist system based on PLC was proposed in this paper to mend the control shortcomings in the traditional system applying relay logic control circuits. PLCs can range from small modular devices with tens of inputs and outputs (I/O), in a housing integral with the processor, to large rack-mounted modular devices with thousands of I/O, and which are often networked to other PLC and SCADA systems.
