Мувинговая компания проверила грузоподъёмность и начала разборку мебели.

Because the subject is компания, and компания is a feminine noun in Russian.

In the past tense, Russian verbs agree with the subject in gender and number:

• masculine: проверил
• feminine: проверила
• neuter: проверило
• plural: проверили

So:

• компания проверила
• компания начала

Even though a company may refer to a group of people, the grammar follows the grammatical gender of the noun компания, which is feminine singular.

It means something like a moving company.

The adjective мувинговая is borrowed from English moving and is understandable, especially in business or advertising language. However, it can sound modern, commercial, or slightly jargon-like.

More traditional or neutral Russian alternatives might be:

• компания по переездам
• транспортная компания
• компания по перевозке мебели
• служба переездов

So мувинговая компания is possible, but it is not the most classic or standard-sounding phrase in all contexts.

Грузоподъёмность means load capacity, weight capacity, or lifting/carrying capacity.

It is a compound noun:

• груз = load, cargo
• подъём = lifting
• -ность = a noun-forming suffix, often like -ness or -ity

So the word refers to how much weight something can safely carry or lift. Depending on context, it could mean the capacity of:

• an elevator
• a truck
• a crane
• a floor
• moving equipment

In this sentence, the object whose capacity was checked is not explicitly stated, so it must be understood from context.

Because it is the direct object of начала.

The phrase is:

• начала разборку мебели = began the disassembly of the furniture

The verb начать normally takes something that is being begun:

• начать работу = begin work
• начать ремонт = begin repairs
• начать разборку = begin disassembly

Since разборка is a feminine noun ending in -а, its accusative singular form is разборку.

Because разборка often takes a genitive noun to show what is being disassembled.

So:

• разборка мебели = disassembly of furniture
• сборка шкафа = assembly of a wardrobe
• ремонт машины = repair of a car

This is a very common Russian pattern: a verbal noun is followed by a genitive noun expressing the object of the action.

Here:

• разборка = disassembly
• мебели = of furniture

Yes. A very natural alternative would be:

• Мувинговая компания проверила грузоподъёмность и начала разбирать мебель.

This means essentially the same thing: The moving company checked the load capacity and began taking the furniture apart.

The difference is mostly stylistic:

• начала разборку мебели sounds more formal, technical, or business-like
• начала разбирать мебель sounds more direct and conversational

Russian often allows both patterns:

• начать + noun
• начать + infinitive

Проверила is the past tense of the perfective verb проверить.

Perfective verbs usually present an action as:

• completed
• whole
• result-oriented

So проверила suggests that the checking was carried out as a completed step.

That fits the sequence in the sentence:

1. the company checked the load capacity
2. then it began disassembling the furniture

If the sentence used the imperfective проверяла, it would suggest an ongoing process, repeated checking, or background action, which is less likely here.

Because начала does not mean that the whole disassembly was finished. It means that the company started that process.

The perfective verb начать focuses on the completed moment of beginning. In other words, the starting was completed, even if the larger activity continued afterward.

So:

• начала разборку мебели = it completed the act of beginning the disassembly

This is very normal in Russian aspect usage.

Yes, Russian word order is relatively flexible, though the neutral order here is perfectly natural:

• Мувинговая компания проверила грузоподъёмность и начала разборку мебели.

This sounds like straightforward narration.

Other orders are possible for emphasis, for example:

• Грузоподъёмность мувинговая компания проверила и начала разборку мебели.
• Разборку мебели мувинговая компания начала после проверки грузоподъёмности.

But those versions shift emphasis or sound more marked. For a learner, the original order is the best one to treat as the default.

The main stresses are:

• мувИнговая
• компАния
• проверИла
• грузоподъЁмность
• началА
• разбОрку
• мЕбели

A particularly important one is грузоподъёмность, because ё is always stressed:

• подъём
• грузоподъёмность

Also note that in normal writing, Russians sometimes replace ё with е, but the pronunciation still has the yo sound if the word is грузоподъёмность.

In many real-life contexts, yes, Russian speakers would often specify it if it is not obvious:

• проверила грузоподъёмность лифта
• проверила грузоподъёмность машины
• проверила грузоподъёмность платформы

But Russian can omit it when the context already makes it clear. For example, if everyone is talking about an elevator in an apartment building, just saying проверила грузоподъёмность may be enough.

So the sentence is grammatically complete, but semantically it assumes some shared context.

Grammatically, мебель is a singular noun, even though in English furniture refers to multiple items.

Its forms are:

• nominative: мебель
• genitive: мебели

So:

• разборка мебели = disassembly of furniture

If you want to refer to individual pieces, Russian often uses:

• предметы мебели = pieces of furniture
• мебель as a collective mass noun

This is similar to English furniture, which is also not normally pluralized as furnitures.

A natural translation would be:

• The moving company checked the load capacity and began disassembling the furniture.

Depending on context, you could also say:

• The moving company checked the weight limit and started taking the furniture apart.
• The movers checked the load capacity and began dismantling the furniture.

The best English version depends on what exactly грузоподъёмность refers to and how formal you want the translation to sound.
