Here’s a look inside the G-BOX Workshop.

Designed for secure storage of tools, oils and equipment while out in the forest, the G-BOX gives you a proper on-site workshop setup.

Available in two sizes, with grab bar or lifting eye options, it’s built to be transported into site and easily positioned where needed.

The video shows the internal layout and storage space.

If you’re setting up or upgrading your in-forest equipment, give us a call and we’ll run through the options.

There are a few choices when it comes to in-forest refuelling…⛽️

You’ll see pickup-mounted transfer tanks, towable bowsers and static tanks positioned at the loading point. Then there are purpose-built grab tanks that can be carried directly onto site.

That’s where our G-TANK and Site Tanks come into their own.

The G-TANK is a 950L UN ADR approved bunded tank, meaning it can be transported legally on the road and then lifted into the site by forwarder or harvester crane.

The Site Tank is available in 850L, 1150L, NS 1525L, offering higher on-site capacity where road transport approval isn’t the primary requirement.

Compared to most pickup-mounted tanks, these capacities allow multiple refuels before needing replenishment, reducing unnecessary fuel runs and keeping machines working.

Because they’re designed for mechanical handling, both tanks can be positioned exactly where the work is happening rather than being limited to vehicle access.

Construction matters too. Both use a polyethylene inner tank, avoiding internal rust and condensation contamination that can affect single steel tanks in damp forestry conditions.
Different sites need different setups.

When the work is deeper into the forest and efficiency matters, purpose-built forestry tanks make the most sense.

Refuelling takes time. Travelling to refuel takes even more.

That’s why in-forest refuelling works best when the tank moves with you, no matter the terrain.

The Clark G-TANK is a 950L bunded diesel tank with UN ADR approval, meaning it can be transported legally on the road. Once on site, it stays close to the machine, cutting down unnecessary travel and keeping production moving.

The grab bar system allows lifting by harvester or forwarder crane, forklift or chains, and the optional bunk bar makes transport on forwarders straightforward. The high impact plastic inner tank prevents condensation and rust contamination, keeping fuel clean in demanding conditions.

If you want to make your operation as efficient as possible, the G-TANK is the one for you.|

The Clark Engineering G-TANK has become a familiar sight on harvesting sites for good reason.

It’s a 950L bunded diesel tank with UN ADR approval for transport in the forest and on the road. The inner tank is high impact plastic, which avoids the condensation and rust contamination you can get with steel.

The grab bar system allows lifting by harvester or forwarder crane, forklift or chains, and the optional bunk bar makes transport on forwarders straightforward.

An integrated manifold system includes aluminium filler cap, dip stick, pressure safety valve, spillstop filler and hose, all protected under a curved, lockable deflector lid. A tool cupboard can be specified to house the pump.

Finished in Dark Grey as standard, with two-tone options available.

Refuelling pumps and hoses are available across our Site Tanks, G-TANK, and G-BOX Drum Stores, with options to suit diesel, AdBlue, and hydraulic oil. ⛽️

Hand or 12v/24v electric pumps can be specified, supplied complete with suction and delivery hoses and stored securely inside the tank or tool cupboard.

For site tanks, a 4-metre hose and dip tube with quick-release couplings can be fitted, with the hose stored coiled inside the steel tank when not in use.

The G-TANK includes an integrated manifold system and refuelling hose, with the option of a modular tool cupboard to house the pump.

Drum stores can also be supplied with hand or electric pumps for clean oil transfer on site.

Sleet, snow, mud - pretty typical Scottish conditions for our G-TANK photoshoot a couple of weeks ago. 🌨️

The G-Tank is a specialist forestry refuelling and storage tank with 110% bunded capacity, a plastic inner tank to prevent condensation and corrosion, and integrated grab bar lifting for handling with harvesters and forwarders. Its UN ADR approval also allows the transportation of fuel in the forest and on the highway.

There’s a reason our G-Tanks are such a familiar sight on forestry sites across Europe.
