Bruk heller sekketrallen enn å løfte flytteesken alene.

Bruk is the imperative form of å bruke (to use).

So this sentence is giving an instruction or recommendation:

• å bruke = to use
• bruk! = use!

In Norwegian, the imperative is often just the verb stem, just like in English:

• Bruk sekketrallen. = Use the hand truck.
• Vent her. = Wait here.

There is no subject like du (you) because imperatives normally leave it out.

Yes. In this sentence, heller means something like rather or instead.

The pattern is:

• heller ... enn ... = rather ... than ...

So:

• Bruk heller sekketrallen enn å løfte flytteesken alene. = Use the hand truck rather than lift the moving box alone.

A very important point: heller can mean different things in different contexts. Here it does not mean either. It means rather / instead.

It is a comparison structure:

• heller = rather
• enn = than

So Norwegian is comparing two choices:

1. bruk sekketrallen
2. å løfte flytteesken alene

In other words:

• Do this rather than that.

You can think of the sentence structure as:

• Bruk heller X enn Y.
  = Use X rather than Y.

Other examples:

• Ta bussen heller enn å gå.
  = Take the bus rather than walk.
• Ring heller enn å sende e-post.
  = Call rather than send an email.

Because løfte is in the infinitive, and Norwegian normally uses å before an infinitive.

• å løfte = to lift

So:

• enn å løfte = than to lift

Even though English often says rather than lift, Norwegian usually keeps å here.

So the sentence compares:

• bruke sekketrallen with
• å løfte flytteesken alene

This is very normal Norwegian.

Sekketrallen is the definite form:

• en sekketralle = a hand truck / a sack trolley
• sekketrallen = the hand truck / the sack trolley

Norwegian often uses the definite form where English might still sound natural with the or sometimes even where English is a bit looser.

Here, sekketrallen suggests a specific one that is available in the situation, like:

• Use the hand truck
  (the one here, the one we have, the obvious one)

That is why the definite form sounds natural.

For the same reason: it is the definite form.

• en flytteeske = a moving box
• flytteesken = the moving box

The sentence is probably referring to a specific box the person is about to lift.

Also, flytteeske is a compound noun:

• flytte = move / moving
• eske = box

So flytteeske means a box used for moving house.

A sekketralle is a hand truck, sack trolley, or dolly used for moving heavy items.

It is a compound noun:

• sekk = sack / bag
• tralle = trolley / cart

The exact English word depends on region:

• British English: often sack trolley
• American English: often hand truck or sometimes dolly

Alene means alone, and here it describes how the lifting is done.

• å løfte flytteesken alene = to lift the moving box alone

Putting alene at the end is very natural because it comes after the action and object:

• løfte = lift
• flytteesken = the moving box
• alene = alone

So the order feels similar to English:

• lift the moving box alone

Yes, it is natural and understandable.

A slightly more explicitly idiomatic version could also be:

• Bruk heller sekketrallen enn å løfte flytteesken alene.
• Bruk sekketrallen i stedet for å løfte flytteesken alene.

Both work. The original sentence is perfectly fine.

The first version with heller ... enn ... feels like choose this option rather than that one.
The second with i stedet for feels more like instead of.

In normal Norwegian, imperatives usually do not include du.

So:

• Bruk sekketrallen. = natural
• Du, bruk sekketrallen. = possible, but now du sounds more like direct address or emphasis

Usually, if you are simply telling someone what to do, you just use the imperative by itself.

Because the second part is expressed as an infinitive phrase, not a full clause.

So instead of saying something like:

• rather than you lift the box alone

Norwegian says:

• enn å løfte flytteesken alene
• than to lift the moving box alone

This is shorter and very common. Norwegian often uses infinitive phrases after enn in this kind of comparison.

Yes, but its position affects what it emphasizes.

Here:

• Bruk heller sekketrallen enn å løfte flytteesken alene.

This most naturally means:

• Use the hand truck rather than lifting the box alone.

You may also see similar structures in other sentences, but heller is often placed near the option being preferred.

So here it is attached to sekketrallen as the preferred choice.

Yes: Norwegian loves compound nouns, and this sentence has two good examples:

• sekketralle = sekk
  • tralle
• flytteeske = flytte
  • eske

English often writes these as separate words or uses phrases, but Norwegian frequently combines them into one word.

That means when reading Norwegian, it is very useful to practice spotting the parts inside long nouns. It helps a lot with vocabulary.
