Key features

Lateral Drive Belt

The drive belt's flexible tread grips the push rod but prevents dust and dirt from building up with user replaceable belt tensioners allows for quick changeover on site. The drive belt drives the push rod up to 150 feet up a lateral connection.

Hinged Mid-Section

The hinged mid-section allows for easier mainline entry access and reduces overall length making it easier in 6 inch pipes with front wheels drive so there is no need to lock the hinge when inserting into mainline pipe.

Pan Tilt Camera

The camera features an integral distance sensor and dual aligned visible lasers, to enable accurate pipe diameter, defect, and object measurement, directly from the control unit.

Flexible Pivot

Horizontal pan and vertical tilt of the deployment arm provides the operator with optimum flexibility.

Observation Camera

Forward facing precision camera with ultra-bright LEDs provide a bright, clear picture within the mainline and makes it easier to see laterals and the main cameral location in the mainline.

Meterage Counter

Close to deployment for an accurate lateral distance measurement.

Backeye & LED Aux Light

Taken from our tried and tested Proteus Back-eye camera and positioned above flow, this colour camera and powerful LED light enables confident cable management during reverse travel.

Pan-tilt Deployment Arm

The standard deployment arm provides horizontal pan and vertical tilt via the front pivot, to enable accurate positioning of the camera/rod prior to launch. For larger mainlines, deployment tubes in varying sizes are available.

Articulated Knuckle

Enables easy deployment of the crawler and prevents water ingression to the connections.

Quick Change Wheel Lock

Easy single tool wheel lock enables you to use a variety of wheel sizes and type to offer significant performance benefits in various pipe diameters and for specific operating conditions.

Lateral Pin

The optional pin adjusts the direction and guides the camera smoothly along the pipe.

Steel Rod Rollers

Enables smooth guidance of the push rod.

Lateral Reel


A single line 1150-foot reel, combining 1000 feet of high strength, Kevlar reinforced inspection cable with 150 feet of flexible 0.43-inch diameter push rod for the lateral camera. The LCR350 pays out matching the speed of the Proteus Lateral Crawler. The extendable arm of the guide roller has a 4-position locking system for ease of deployment at the rear of the vehicle.

Lateral Reel

Mainline Reel


Used in conjunction with the lateral reel this fully automatic reel provides a distance capability of 1150 feet (350 meters) to power the crawler along the pipeline. It uses our tried and tested Kevlar reinforced inspection cable, and has all the functionality and safety features of the lateral reel. For additional smooth friction-free guiding, an optional van guide pulley is available.

Automatic Reel

Van-fit Configuration

Dual reels with installation flexibility in van arrangements (example shown below) are used to drive the LT150 crawler. The Lateral Reel gives you 150 feet (48 meters) of mainline capability to then extend the main camera over 150 feet into a lateral pipe, while the mainline reel provides cable to the crawler for runs of over 1150 feet (350 meters) within the mainline pipe. Ultra-smooth operation is provided by a powerful motor and cable layering mechanism, specially designed for uninterrupted, tangle free pay-out and re-winding. Clear safety screens prevent contact with the cable whilst coiling, and for additional safety there is a rigid lid and an e-stop button.

Diverse Functionality and Range

The LAT150 comes with 8x wheel drive and observation and reversing camera’s included as standard, making traversing awkward in-pipe obstacles an easy task in pipes as small as 6 inches.


The self-propelled lateral camera unit allows you to inspected lateral pipes as small as 2 ½ inches with over 150 feet of deployment range, all while offering Pan and Tilt camera functionality with laser measurement. With diverse functionality and range and Minicam’s industry renowned reliability the LAT150 is the go to product for any mainline to lateral survey requirement.

Manageable Manoeuvrability

The LAT150 offers a multitude of options to help overcome challenging situations and give complete control of each launch. The system has flexible but easy to use options available such as, various configurations and sizes of wheels, deployment tubes and the lateral pin.

Deployment Tubes

For larger mainlines, to enable accurate positioning of the camera prior to launch, the LAT150 can be fitted with various sized deployed tubes. The unique design of the pivot provides quick, easy and tool-less attachment of deployment tubes in any size.

Wheel Configurations

Minicam’s patented quick release wheel lock enables the user to quickly change wheel configurations of the LAT150 to launch in main lines from 6 inches / 152.4mm diameter. Wheel sizes compatible with LAT150 are 90mm, 115mm and 140mm.

Optional performance wheels are available in high grip and carbide which offer significant performance benefits in various for specific operating conditions, such as greasy and/or plastic pipes.

Lateral Pin

A useful addition to the Pan-tilt and Laser Camera CAM050. simply attach the pin to assist in directional guidance within a lateral pipe. The pin helps to overcome entry to bends & junctions and guides the camera smoothly along the pipe.
