Sizes of lifts for car service: how to choose dimensions for the tasks of the STO

Choosing a lift with the wrong dimensions leads to the fact that 30% of the workspace of the car service is used inefficiently - either the cars do not fit on the platform, or there is too little space between the racks for masters. For example, a two-point lift with a width between the racks 2.8 m m not suitable for maintenance Mercedes Sprinter (minimum required width - 3.2 m m m) and the height of the pick-up 100 mm It will make it impossible to repair cars with low clearance, such as Porsche 911. The standard ceiling height in boxes (3.5-4 m) limits the maximum height of the lift: for four-point models, it should not exceed 1.8–2 mOtherwise, the risk of damage to the body during the lift increases by 3 times.

The problem is complicated by the fact that manufacturers often indicate only the characteristics of the product. maximum load capacity (e.g. 3.5 or 5 tonnes), withholding the critical dimensions: platform-length (Important for long-wheelbase cars) pick-up (critically for sports cars) and polewidth (Determines the access of the master to the suspension). As a result, after the purchase, it turns out that the lift is not compatible with 40% of customer cars, and the redevelopment of the box costs 15-20% of its cost. We will then discuss how to avoid these mistakes by relying on GOST R 51709-2001 (requirements for equipment of service station) and practical data on popular models of lifts Ravaglioli, Nussbaum and MAHA.

Standard lift dimensions: table by type and load capacity

The size of the lift directly depends on it construction and target-purpose. For example, scissor models occupy a minimum space in width (from 1.8 m), but have a limited lifting height (up to 1.6 m), which makes them unsuitable for work with the bottom of trucks. At the same time, four-point lifts with a platform length 5-6 m They allow minibuses but require a box of at least 4.5 m wide.

Below is a table with typical dimensions for different categories of lifts, relevant for 90% of car service stations in Russia. The data is based on the analysis of the model range of leading manufacturers and requirements. Technical Regulations of the Customs Union TR CU 018/2011 (Equipment safety).

⚠️ Attention: When choosing a four-story lift, keep in mind that polewidth It is indicated for each pair separately. For example, a model with a parameter "2.4-3.0 m" means that the distance between the front racks is 2.4 m, and between the rear - 3.0 m. This is critical for vehicles with a wide wheelbase (e.g., Ford Transit) where the rear wheels may not fit on the platform.

Minimum box sizes for lift installation

Mistake #1 in car service planning – Ignoring safety-zone around the lift. I agree. SNIP 31-06-2009 (premises for storage and maintenance of vehicles), the minimum distance from the rack of the lift to the wall or other equipment shall be:

• 📏 0.8 m m - for two-stage models (provides access to tools and freedom of maneuver);
• 📏 1.2 m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m m - for four-pillar and plunger (taking into account the dimensions of lifted trucks);
• 📏 0.5 m m m m from the rear of the platform to the wall (but not less than 1 m for models with a length of >5 m).

In practice, this means that for the installation of a standard double-pillar lift with a width between the racks 3m You'll need a box wide:

3 m (lift width) + 0.8 m (left passage) + 0.8 m (right passage) = 4.6 m

If the width of the box is smaller, the craftsmen will have to work in cramped conditions, which increases the risk. carve-up (e.g. scratches on the body when opening doors) or trauma (blows on the counters).

The height of the pickup: why 100 mm is critical for sports cars

Height of pickup (the minimum ground clearance, at which the legs of the lift can catch on the doorsteps of the car) is one of the most underrated parameters. For example, a lift with a lift height 120 mm Can't lift it.

• 🚗 Porsche 911 (Clearance of 95-105 mm);
• 🚗 Audi R8 (clearance of 100-110 mm);
• 🚗 Lamborghini Huracan (Clearance of 110 mm in standard position)

Solving the problem:

1. Use the lifts with height-adjustable (e.g. models) Ravaglioli X-Tronic with a range of 80-140 mm).
2. Install. adapters for low-vehicle (cost from 15 000 rubles), but keep in mind that they reduce the load capacity by 10-15%.
3. For premium car services optimal scissor-lift (from 70 mm), for example, MAHA ML 3.5.

Width between racks: how to calculate for specific cars

The width between the racks determines whether the car will fit on the lift. without risk of locking mirrors or doors. For the calculation, use the formula:

Minimum width = width of the car in mirrors + 0.4 m (spare)

Examples for popular models:

• 🚘 Toyota Camry (width of mirrors 2.1 m) 2.5 m m m m;
• 🚐 Volkswagen Crafter (width 2.4 m) → required 2.8 m m;
• 🚚 GAZ Next (width 2.5 m) - required 3.0 m.

⚠️ Attention: For asymmetrical lifts (where the front pillar is shifted forward), the width is indicated separately for the front and rear pair. For example, the model Nussbaum KFJ 4.0 It has a width of 2.8 m in front and 3.2 m in rear. This allows you to service both passenger cars and minibuses, but requires accurate positioning of the car at the arrival.

Measure the width of the widest cars in your car service (by mirrors);

- Add 0.4 m to this value;

Compare it with the passport data of the lift (take into account asymmetry);

- Check whether there is a possibility of adjusting the width of the racks (some models provide a backlash of ± 50 mm).

Platform length: why 4.5m is not a universal size

Standard length of the platform of a two-stage lift - 4.5 m It is suitable for 70% of passenger cars, but it causes problems with:

• 🚗 Long-wheelbase sedans (e.g., Mercedes S-Class with a wheelbase of 3.16 m;
• 🚐 Microbuses. (e.g., Ford Transit with a base of 3.75 m);
• 🚙 Cars with trailers (At least 6 m in length is required).

Decision:

• 📌 For universal STOs, choose models with lengthened platform 5.0-5.5 m (e.g., Ravaglioli H 5.3).
• 📌 For truck service providers, plunger lifts with a length of 6-12 m.
• 📌 Use it. platform-extension (cost from 25 000 rubles), but keep in mind that they reduce the load capacity by 500-1000 kg.

Installation errors: what causes accidents and penalties

According to the data Rostrud60% of inspections of car service providers reveal violations when installing lifts, of which 40% are associated with the wrong size selection. Top 3 mistakes:

1. Ignoring the load-bearing capacity of the sex. The lift weighing 1.5-2 tons requires a concrete base with a thickness of at least 200 mm with reinforcement. In 30% of cases, the floor sags after 1-2 years of operation.
2. No gap for ventilation. There should be a gap between the platform and the floor. 50-80 mm for air circulation (requirement) SP 60.13330.2016). Otherwise, condensation leads to corrosion of the hydraulics.
3. Failure to comply with ceiling height. If the lift height is 2.1 m, and the ceiling in the box is 3.5 m, then for GAZelle Next (height 2.7 m) is only 0.4 m of stock - this is not enough for safe repair of the roof.

⚠️ Attention: Installation of the lift without project and approval with Rostekhnadzor (for carrying capacity > 3 tons) entails a fine of up to 200 000 rubles. on the 9.1 RF Administrative Code. The project should include:

• 📄 Calculations of the load on the foundation;
• 📄 The scheme of accommodation taking into account evacuation routes;
• 📄 Certificates of conformity of the lift TR CU 010/2011 (on vehicle safety).
