Wireless Skip Weighing System
Skip hire companies facing new legislative and environmental issues have to look at spreading the costs associated with such change. This has meant a tighter control on the total filled weight of skips. Any excess weight in the skip have to be accounted for and charged accordingly.
The Problem:![rubbish skip](/userfiles/applications/skip_weighing_system.jpg)
Modifications to exisiting skip vehicles can be a costly and lengthy process. Vehicles can be out of service for several days and have to undergo expensive, labour intensive, welding.
The Solution:
A skip loader truck is fitted with two T24-SA wireless strain gauge acquisition modules contained in shackles which are connected to standard skip chains. A T24-HA wireless handheld display is used to sleep and wake the T24-SA devices and provide a summed display from the two acquisition devices. The handheld offers Gross/Zero toggling of the display so it can be zeroed just before each customer's refuse is added to the skip. In this system a printed ticket is required on the spot for the customer by the company's own printer. A T24-SO serial output module triggered from a key-press on the handheld and connected to the customer's own serial printer, prints a ticket containing company information and the net weight of the refuse along with a log number. The printer and T24-SO are neatly housed in the truck cab. An optional module for the T24-SO would allow the ticket to contain time and date. Using a single 3.6V Lithium battery (Saft LSH20) per T24-SA, a life of three years can be achieved when the system is used for 20 pick-ups per day where each pick-up involves the system being active for 10 minutes. If the company wished to use Mantracourt's own T24-PR1 thermal printer, the T24-SO would not be required.
