Back Raking Machines
Aquatic Control Engineering (ACE) offers robust, self-contained Back Raking Machines — designed to remove debris and keep intakes clear at pumping stations, water intakes and drainage systems. Compact, efficient and turnkey-ready, these units help maintain reliable water flow and protect upstream infrastructure.
Versatile Design
Our Back Raking Machines are engineered for effective debris removal — whether for large or small intakes. The built-in trash-screen and chain-driven rake system lift debris smoothly up and over the unit, ensuring reliable clearing of vegetation, twigs, litter and other material that could block or damage intakes.
Self-Contained & Easy Installation
These machines arrive as complete, self-contained units. They can be quickly installed on-site and connected to power — avoiding complex civil works and reducing installation costs. That makes them an ideal choice for retrofit solutions or new installations alike.
Integrated Conveyor System
For simple waste management, we offer optional conveyor systems that transport removed debris from the dump area directly into a skip. This streamlines maintenance and disposal, keeps the site clean and saves labour time.
About Back Raking Machines
The ACE Back Raking Machine combines a robust trash-screen, a chain-driven rake mechanism and optional conveyor disposal — all in a compact footprint. It lifts debris out of the water and deposits it clear of the intake zone. Because it’s self-contained, installation is quick and cost-effective, making it particularly suited to smaller pumping stations, drainage intakes, or retrofit projects where space and civil-works budgets are constrained.
Why Choose Back Raking Machines
01
Enhanced Efficiency
The chain-driven rake and screen system ensures smooth, effective debris removal — reducing risk of blockages and maintaining continuous water flow.
02
Cost-Effective
As a self-contained unit that connects directly to power with no major civil works, installation costs and site disruption remain minimal.
03
Versatility
Suitable for a wide range of debris sizes, from light vegetation to heavier branches or litter — and compatible with various intake geometries and flow conditions.
04
Simpler Debris Management
Optional conveyor systems transport waste away automatically, making disposal easy and keeping intake zones clean and low-maintenance.

Frequently Asked Questions
A back raking machine is used protect pumps and other infrastructure from debris floating downstream. Typically, back raking machines are for smaller areas up to 10m2.
The back raking machine has a built-in trash screen, and lifts the debris up the screen and over the top of the back-raking machine, into a hopper.
The back-raking machine is a single, self-contained machine, which can be quickly and easily installed and connected to power to keep site costs to an absolute minimum.
Back raking machines are suitable for most applications. Not suitable for sites with blanket weeds such as cot, or large debris can be expected.

More About Back Raking Machines
The ACE Back Raking Machine is a heavy-duty, self-contained debris-management solution for pumping stations, drainage intakes, urban runoff systems and water-management infrastructure. Constructed from galvanised or stainless steel, it features an adjustable chain-driven rake and a built-in trash screen to capture and remove debris such as vegetation, litter, silt and floating waste.
Ideal for channel widths of up to 4 metres and water depths up to approximately 4 metres, it’s optimised for smaller intakes where space, civil-works budgets and maintenance access are constrained. Its durable drive unit — designed for low power consumption and easy maintenance — ensures continuous, reliable performance with minimal downtime.
Aquatic Control Engineering
Because the Back Raking Machine is self-contained and connects directly to power, installation, retrofit or replacement is straightforward — a major advantage over manual cleaning or complex overhead screen-cleaning systems. The optional conveyor system simplifies disposal, allowing debris to be conveyed directly into a skip, making maintenance safer, cleaner and more efficient.
