Troll Brew Table System

What is the Troll system?

The Troll system is a product line of brew tables, frames and accessories specifically designed for Brewtools brewing systems and Unitanks.

The Troll brew tables with crane (accessory) is an awesome combination that makes it possible to lift the malt pipe during and after sparging with precision. This is especially useful in locations where having a ceiling mounted lifting device is not possible or beneficial. It can also pivot to allow for the malt pipe to be lowered to an adjacent side table or similar. With the included wheels even more flexibility is added.

The current Troll product line consists of the following main products.

Brew tables (low and tall model)
Brew crane (100 kg / 220 lbs)
Unitank frame
Frame with plate

Combinations and usage

The brew tables and frames have a modular design allowing multiple units to be joined together. More details on this in the assembly section. This allows for lots of combinations like pictures show below.

Crane position and required ceiling height

The crane will need to be able to lift the total height of the brewing system and the malt pipe combined. For our systems, the following minimum lifting height is needed.

B40Pro – 86cm
B80Pro – 106cm
B150Pro – 133cm

Use the table below and find your table model, low or tall. Follow the line towards the right to find a height number that is more than what is required. Follow the column up to find the crane position and down to find the required ceiling heigh needed. If you have more ceiling height than needed, feel free to select a higher crane position if you like.

Example:

I have a B80pro and a Troll Brew Table low model.

Lifting height needed for B80pro is 106 cm minimum. From the table below I find the low model and follow the row to the right until I see a number greater than 106 cm, which is 110.9. Following the column upwards I find that the telescopic position of the crane is 2. Following the column downwards I find that the ceiling height needed in this position is 194.5 cm. I have a 239 cm ceiling height where I brew, so I considered for a moment mounting the crane in the highest position even though I don’t have to, but then I remembered that I need to be able to move the brew table out through the garage door to clean it. The garage door is 220 cm tall so I’ll go by position 4 which requires 214.5 cm height.

Assembly of brewing table

A spanner or wrench might come in handy. The rest is provided in the package.

Start by placing the a table frame on the ground. The upper and lower frame are identical and have no dedicated way up or down, however the center bar should point towards the front of the table like show in the picture below.

Install the castor wheels with brakes in the front holes like shown in the picture to gain easy access to the brakes during use. The castor wheel with brakes cannot be used on the back in combination with the crane.

Install the castor wheels without brakes on the back.

Install the legs by screwing them by hand on to the threaded stem on the castor wheels. Note that the leg has holes for joining it with additional tables. The holes should be on the upper part of the legs. When the legs are screwed in, don’t tighten using tools until the top frame is installed.

Place the top frame oriented the same way as the lower frame (center bar pointing towards front) on the vertical legs and use the included M10x50mm bolts to fix it to the legs. Use the included Allen key (6mm) to tighten.

Now, use a spanner or wrench to tighten the nut on the castor wheel.

Attach the five silicone strips onto the top frame. The silicon strips act as spacers for the M10 bolts fixing the legs against the top plate.

Place the top plate over the table frame so that the crane hole is situated on the back side. Choose whether you want the crane on the left or right side.

Included in the package are silicone plugs for sealing the open holes to avoid water ingression. Use them if you want.

A bracket for counterflow cooler (accessory) can be mounted like shown on the picture below.

Assembly of crane

Before mounting the crane, we advise that you decide how tall you need it to be. Details are described in a previous section.

Start by mounting the crane bottom support piece. This is placed on the lower frame on the same side as the hole in the top plate. Use two M8x50mm bolts along with plain washer and nut from the crane bolt kit to fix the crane bottom support to the lower frame.

Find the support leg with a welded-on nut. Screw the adjustable foot into the nut so that the nut is pointing towards the adjustable foot. The support leg has a hole on the opposite end to fix it to the crane bottom support using a M8x50 bolt like shown on the picture. It is important that the support leg is mounted such that it will support the brew table while pivoting sideways.

Place the two nylon rings into the holes at the bottom support piece and the top plate. They will fit snugly.

The nylon spacers/rings can absorb moisture and expand slightly in some climates. If they are hard to install, we recommend drying them in an oven at 40-50 degrees C for 1-2 hours before use.

Take the crane column pipe with the biggest diameter. Make sure the holes point upwards. Insert it into the nylon ring in the top plate and further into the nylon ring in the bottom support piece.

Using two M10x80mm bolts, fix the crane boom to the middle crane column. The end with 2 holes in the middle crane column should be pointing upwards. Use the nylon liner ring with hole as shown on the picture, as it will make the joint even better. It is important that both bolts go through the middle pipe.

Fit the nylon liner ring without hole onto the bottom crane column and slide the top part of the crane into the lower column.

Now, with the crane in its lowest position, prepare to install the nylon pulleys in the crane boom.

There are five possible positions for the front pulley.

Decide based on brewing system diameter and where on the table top you want it to be positioned.

The distances below refers to the pulley position i picture further down and are measurements from the crane bottom column to the rope.

34.5cm
39.5cm
44.5cm
49.5cm
54.9cm

Before installing the pulleys, the winch rope must be pulled through the boom so that the thimble is sticking out of the boom end. Then lead the thimble back in throught the boom end and out of the squared opening depending on the distance you would like.

Fold the rope around the front pulley and by pulling the rope carefully from both ends the pulley will slowly be guided into the boom until it eventually hit the hole. Install the clevis pin and lock it with the cotter pin.

Install the back pulley using the clevis pin and cotter pit to lock it.

Find the winch bracket and mount it to the winch using the two M10x20 mm bolts using plain washer and nut.

With the winch mounted to the bracket and with two M10x80 bolts at hand, lift the crane top assembly upward until the needed height is reached. Put the bolts through both the backet and the column and secure it with plain washer and nut.

Counting the number of visible holes above the nylon part on the crane column and adding 1 will correspond to the position in the table further up.

Example: If you see 5 holes above the nylon part, the cran is in position 6 (highest position)

Attach the spring carabiner and the low-profile lifting bracket.

Attach S-hooks.

The 9mm holes on the lifting bracket has the following distances:

32cm
37cm
42cm
47cm
50cm

Placing a Unitank on top of the Troll Unitank frame

The Troll Unitank frame has slotted holes especially made for our F40/F80/F100/F150/F300 Unitanks.

Assemble the frame with castor wheels and lock the wheels. We recommend having the two lockable castor wheels at the front. Use nuts and acorn nut.

Place the nylon spacers on to the frame at about the correct place so that the bolts will fit through the frame. Measure the distance between the legs to be sure.

Turn the Unitank upside down or lay it down to unscrew the adjustable feet. Make sure the threads are clean.

Place the Unitank carefully on top of the nylon spacers as centered as possible. Make sure the front of the Unitank matches the front of the frame. Have someone hold the Unitank to avoid it from falling over while someone starts to screw the M10x80mm bolts from below. Don’t tighten them until all four bolts are in place and the Unitank is centered on the frame. Then tighten the bolts.

If you plan to connect the Unitank frame with another Unitank frame or a Troll frame with plate it is recommended to do that prior to placing the Unitank. The reason for this is that two of the castor wheels must be taken off.

Safety consideration when using the Troll system

When it comes to lifting and moving heavy items around, you should always have your own and others safety at mind.

Always take extra precautions when moving heavy items.

As the crane is mounted on a corner of the brew table it can potentially pivot in two directions, however with load it must only pivot the shortest way towards the support leg le.

Before operating the crane, always make sure the support leg is correctly positioned and that the adjustable foot is tightened to the floor. Castor wheels brakes must be engaged.
