Automatic Hydraulic, Chain and Cable Scrapers
Automatic Hydraulic Scraper System
- No large Ram Box at the end of the passage
- Flexibility on position of ram, as no electrics are used
- Fully galvanised top and base track
- Heavy duty scraper blades
- One panel can operate up to 6 passages
- System monitored by pressure sensor and relief valve
- Pressure dump valve to relieve pressure on start up of motor
- Very efficient with low cost maintenance
- Very simple to operate
The Scraper Blade
Each Scraper Blade is made individually to suit the width of your passage way, they can be any width up to 6 metres. The tracking has a Base and a Top Track. The Base Track gives flexibility during installation, if the ground within the passage is not level.
The Top Track can either have a Rounded Profile or a Square Profile, the square profile is more commonly used where vehicles are regularly driven over it.
The Ram Box
The Ram Box is placed into a sump which is cut out of the floor in any position in the passage way. This allows the passage ways to be of different lengths without the need for an extra motor, therefore eliminating the need for extra Hydraulic hose.
This is the only system to have no electrics in the Ram Box, so no problems will occur due to moisture and slurry entering the box.
Then a top track is placed over, giving the Ram full protection and allowing the Scraper to travel over the top of Ram to the park position.
Scraper Operation
The system can be operated in two ways, either one passage at a time, driven by a 1.5kw motor, or two passages at a time, driven by a 2.2kw motor. The second option usually applies when cubical passages and feed passages need to be run simultaneously.
6 passages can be operated from one automatic sequence, up to 24 times a day. The pressure sensor monitors the movement of all the Rams, detecting cowdown and in such situations will turn the motor off for one minute, after this one minute the passage will try again. If the cow has moved, the scraper will carry on to do its sequence. If the cow is still there this passage will shut down and other passage ways will not be affected and they will carry on there Automatic Sequence. Other features include Oil Level Gauge, Filter Indicator Gauge, Filler Breather Cap and Pressure Dump Valve.

Automatic Chain Scraper System
With over 20 years of experience working with Automatic Scraper Systems, we have developed Storth Scrapers; the only way forward to increase efficiency and create a more healthy environment for your animals.
- Deep casehardened chain
- Quick tensioning method
- Heavy duty scraper blades
- System monitored by motor current sensing
- One panel can operate up to 4 passages
- Adjusted to suit all types of building
- Fully galvanised corner boxes
- Very easy to operate and install
The Storth chain scraper panel is fully electronic and simple to operate. Automatic scrapes can be programmed up to 24 times a day and manual scrapes can take place when in auto. During scraping the panel monitors the amps the motor is using, if there is a cow down the motor amps rise and shut down the motor, the scraper will back away 1 meter there after will try again, if there is no obstruction the scrape will carry on, if there is still an obstruction the panel will shut down until the problem is sorted. The panel can operate 2 motors allowing 4 passages to be scraped out. The maximum length is 72 meters (240 ft) the maximum width is 6 meters (18 ft).
Motor driven
The system is driven by a robust 0.55kw motor with an output speed of 5.2rpm. Also a limit switch is fitted on the output shaft which controls the distance the scraper blades travel. Most systems allow the scrapers to stall out the motor against buffer springs, which sees a surge of current but this causes a lot of strain on the system. Therefore the Storth system prolongs the life of components.
Galvanised Corner Boxes
Corner boxes are made of 6mm steel and are fully galvanised. Corner rollers are made of cast steel with two centre bearings which allows the roller to move efficiently and keep its shape, the centre pin has a grease point to allow grease to the bearings. The chain has 14 mm diameter links pre-stretched to 20 tonnes. The chain is also case hardened to minimise wear factors.
Automatic Cable Scraper System
- Cow friendly on cow's feet 9.5mm plastic coated stanless stell cable
- No catapult effect or bacteria breeding in polyester rope
- Quiet in operation with low running cost and minimum maintenance
- Sensors count winch revolutions eliminating electronics from contact with slurry and strain on motors, cable and corner rollers increasing component life expectancy dramatically
- The most technically advanced control panel on the market today with full and reliable cow down protection. Why jeopardise your animals welfare?
- No slurry travailing on cable giving clean areas where motors and rollers are positioned unlike rope or chain
Drive Winches
Storth Drive Winches are built on to a sturdy galvanised frame which can be surface mounted, wall mounted or mounted above head height on a purpose built stand. Mother winches are 0.55kw with the drum shaft rotating on high quality bridge bearings. Sensors are mounted on the frame to count the winch revolutions keeping clear of any contact with slurry. Areas round the motor winches are kept very clean as slurry cannot travel along the cable unlike other systems which pool slurry around the drive winches.
Corner Pulley Box & Stainless Steel Cable
Corner roller boxes are contstructed of 6mm steel fully galvanised to give maximum protection to the inner pulley. Pulleys are made of high grade cast with a phosphor bronze bush which rotates smoothly on the centre grease pin allowing quite and reliable running operation.
Cable is 9.5mm stainless steel cable plastic coated, as the cable glides along the ground with very little weight. This allows very little wear on the cable itself for a maximum working life.
Control Panel
Storth Control Panel is a state of the art unit which gives great flexibility to the cable scraper. Frost protection which moves teh scraper blades 1mt forward and backwards when low temperatures are reached, 24 automatic sequences can be set. It counts revolutions of drive winches from start position to end position, park position of scrapers can be anywhere in passages. Motor amps are monitored at all times to protect motor winches from overload and the most important function is the cow down facility which senses a cow down backs away a metre then tries one minute later allowing the animal to move. If the scraper comes across the animal again within the metre the system shuts down till the problem is resolved.
Yard Scrapers
- Fully galvanised 6', 6'6" and 7'6" Yard Scraper
- Cleaner yards
- Reduced scraping time
- Reduced spillage
- Follows uneven surfaces
- Easily changeable parts
- No pivoting points
A-frame and 3-point linkage standard on all models. All yard scrapers are twin bladed, using hard wearing high-impact strength rubber. With perfect elasticity, high tensile strength, good impact resistance and little elongation, the Storth Yard Scraper gives the very best results.
