Here’s how a Surf Rake works: one operator drives a towing tractor while the machine’s tines rake the sand, lift debris onto a moving conveyor, and leave clean, groomed sand behind in a single pass. It collects everything from cigarette butts to softball-sized rocks, up to six inches deep. We detail the full process, step by step, below:
The beach cleaner’s moldboard levels uneven areas in the sand to ensure an even surface for cleaning across the entire width of the machine. It also controls how deep the tines of the Surf Rake penetrate the sand.
The moldboard also protects the conveyor system by guiding the machine over large submerged objects, instead of meeting them with directly with the conveyor mechanism, like a sifting style machine would.
Offset, individually-replaceable stainless steel tines mounted on a rapidly-rotating belt-covered bar flight conveyor then rake through the sand and separate debris from the sand–both on submerged and on the surface.
The tines fling the debris against the curved moldboard and onto the elevating portion of the conveyor. This knocks sand off the debris. Any residual sand then falls through the perforations in the conveyor, as it’s carried up to the hopper.
Once the hopper/bucket of the beach cleaner is full, it can be hydraulically raised and tripped to dispose of its contents into a truck or container up to 9 feet high (HD models) or deposited on the ground (400).
A number of proprietary features make the SURF RAKE the most effective and reliable beach cleaner on the market. We’ve been refining the SURF RAKE since 1966, so that each component is optimized for maximum reliability & longevity.
The S-belt is a perforated NRB Rubber belt with nylon layers that is practically wear-resistant and contains rows of mounted stainless steel tines. When the tines capture debris onto the beach cleaner’s conveyor, the perforations allow residual sand to fall back onto the beach, allowing the beach cleaner to only remove debris, not the sand.
This improves performance and longevity in that it maximizes tine penetration and removal of extremely fine debris like cigarette butts, while reducing the risk of residual sand removal, extra dump cycles, and bulk waste removal costs. The conveyor is also easier to clean and clear of debris than other methods.
The SURF RAKE beach cleaner line features a hydraulic drive for smooth operation with major advantages:
First, it provides excellent maneuverability. Power is transferred through a flexible hose, allowing the beach cleaner to clean while turning in the tightest of areas. Second, the beach cleaner’s flow control permits fine adjustments of the conveyor belt speed, independent of the tractor. Third, the hydraulic drive maintains the operator’s safety by eliminating exposed turning shafts. Fourth, the adjustable over-flow engages and resets automatically to protect our beach cleaners from oversized objects. Lastly, as a purely mechanical system, it does not contain any failure-prone electronics or proprietary components that make repairs in the field impractical.
Hundreds of double-torsion, three-coil stainless steel tines are mounted in offset rows on the conveyor. Hundreds rake through the sand every second creating a grid that removes even the smallest unwanted debris from the sand; such as, glass, cigarette butts and pop-tops.
The stainless steel tines offer superior durability and corrosion resistance, which is essential in saltwater environments. Tines are individually replaceable on each beach cleaner for simplified maintenance.
The Surf Rake uses a four-stage process: (1) a moldboard angles inward to funnel debris toward the tines, (2) rows of stainless steel tines penetrate the sand and lift debris, (3) an S-belt conveyor carries material up while sand falls back through gaps, and (4) debris is deposited into a hydraulic dump hopper for removal.
The moldboard is an angled front plate that serves three purposes. First, it guides and funnels debris inward toward the tines as the machine is towed. Second, it grades the beach before cleaning, which allows for even cleaning across the width of the machine and a smooth beach, regardless of sand castles, holes, or other beach surface inconsistencies. Third, it protects and guides the conveyor system over potentially-damaging large submerged objects.
Hundreds of stainless steel tines layered in offset rows penetrate the sand, combing through it to dislodge and lift debris. The offset pattern provides better coverage and collects debris of varying sizes more effectively than aligned rows or fixed screens.
Stainless steel tines resist corrosion from salt water and salt air — critical in beach environments. They are flexible enough to deflect over embedded objects without breaking and are individually replaceable when worn.
The S-belt conveyor carries debris up to the hopper while pinballing it in an S-shaped path that creates a tumbling action, shaking loose sand from collected material before it reaches the hopper. This reduces sand loss and improves the ratio of debris-to-sand collected.
The Surf Rake uses a hydraulic dump hopper actuated from the tractor cab. With HD Surf Rake models, the hopper lifts and tips to discharge collected debris — no operator needs to leave the cab. In the Model 400, the hopper dumps contents on the ground.
The Surf Rake’s mechanical components are driven by the tractor’s hydraulic PTO output. No separate engine is needed on the implement — all power comes from the tow vehicle.
