Troglotech T815/T850 Battery-operated Crawler System, Large Auto Drum

T815/T850 Battery-operated Crawler System, Large Auto Drum by Troglotech

Our new Crawler System is battery-powered, robust and all you need for successful surveys

robust, safe, zero emmisions, lightweight

• 300 metre Auto Drum 4" to 24" Centred - up to 39"/1000m
• Pan & Tilt with 'auto-home' to simplify operation
• complete system fully waterproof to IP67
• full days operation from supplied batteries
• Wifi Video Streaming to customer
• reversing camera
• 25kg inc crawler
• Inclinometer
• Powerful Sonde
• Lithium-Ion powered
• 4mm Kevlar cable
• 300m as standard
• steerable as standard
• locking wheel bolts
• cable auto-layering
• Elevator

The complete system is Lithium-Ion battery-operated using the latest technology for long mission times and this means that the system is lightweight and highly portable - and very economic to use. As usual with Troglotech products, the system is highly robust with the crawler being machined from solid brass and stainless steel.

With a range of quick-release wheel sets (the wheel bolts are locked into position for security) you can survey the full range of pipe sizes from 4" (100mm). The crawler is steerable and has a reversing camera and lights so that a survey can be performed in either direction.

The batteries on the crawler have a long mission time (up to a full days inpection work) are quick-release and can be charged on-site or via a mains supply.

safety first

Our systems are all battery operated so there are no dangerous voltages or generators required. We use the latest battery technology to provide a full days work from two crawler batteries and a single charge of the control unit battery.

why battery power?

On most crawler systems up to 90% of the power is lost in the main cable. The cable can be increased in size with more copper to reduce the loss - but then the crawler needs to be bigger and heavier. In addition the cable voltage is often at lethal levels.

We have produced a crawler that carries its own power source meaning that the main cable does not conduct any power allowing it to be much lighter. The composition of our cable is mainly Kevlar and the three small conductors only carry signals at safe voltages below 5V.

a complete automatic crawler system for 4" to 36"

our crawler system competes with hugely expensive mainline crawler systems for the price of a pushrod system

Troglotech's designers worked on the early, bulky crawler systems at Pearpoint from the 80's to the 00's. These were huge systems that required generators, cranes, custom-built vans and needed a team to operate. Troglotech decided that this was completely the wrong method to provide what is essentially a video camera for inspecting pipelines

To this end, Troglotech designed a crawler that carried its own power supply using in custom-designed Lithium-Ion batteries. This removed the need for the heavy support equipment.

• No need for generators
• No cranes needed
• No heavy main cable - we use a 4mm Kevlar cable - 300 metres weighs less than 10kg
• No need for multiple crawlers - our crawler is used from 4" to 36"
• No need for large power supplies, our batteries are quick-release and weigh 2kg
• No need for heavy cable drums, our is automatic and weighs around 15kg
• No need for a custom-made van, our system will fit in the trunk of a sedan - ready for 300m survey of 36"
