1 Premises and Scope of Application
The hot tub is enclosed and packaged to allow lifting by mobile crane, mechanical arm, helicopters, and similar lifting equipment. This type of handling becomes necessary when the access path to the installation site presents insurmountable obstacles (walls, narrow gates, elevation changes) or when installation occurs in locations difficult to reach by land.
The hot tub structure is robust and resistant, designed to withstand the stresses of proper lifting. However, it is essential to pay maximum attention to the positioning of the sling straps and lifting techniques to avoid damage to the structure, external cladding, and internal components.
WARNING: Lifting operations with mechanical equipment must be performed exclusively by specialized and certified personnel according to current regulations.
2 When Lifting is Necessary
2.1 Typical Lifting Cases
Lifting with mobile crane or mechanical equipment becomes necessary in the following cases:
- Installation on terraces or balconies of upper floors without vehicle access
- Passage over buildings, boundary walls, hedges, or fences
- Access through internal courtyards with openings insufficient for passage
- Isolated mountain locations reachable only by air (mountain huts, mountain hotels)
- Historic centers with restricted traffic and limited traffic zones
- Installation on ships, yachts, or boats
- Sites with stairs, steps, or elevation changes that cannot be overcome with a pallet truck
2.2 Preliminary Feasibility Assessment
Before planning the lift, perform a feasibility assessment that includes:
- Measurement of required lifting height and distance
- Identification of mobile crane unloading point (ground stability, pavement load capacity)
- Verification of maneuvering space for the mobile crane (arm radius, required reach)
- Presence of overhead obstacles (electrical cables, telephone lines, branches)
- Permits for public land occupation (if mobile crane must be stationed on the road)
- Weather conditions forecast for the day of lifting (wind, rain)
NOTE: For complex lifts or critical conditions, request a preliminary site inspection by the mobile crane company. An experienced operator can assess feasibility, identify risks, and propose alternative solutions (e.g., mobile crane with greater reach, lifting from a different point, helicopter use).
3 Types of Lifting Equipment
3.1 Mobile Crane (Truck-Mounted Crane)
The mobile crane is the most commonly used lifting equipment for positioning hot tubs. It is a truck equipped with a telescopic hydraulic crane mounted on the chassis.
Mobile crane advantages:
- Versatility and availability (present in all cities)
- Contained costs for standard lifts (300-800 euros)
- Speed of execution (30-60 minutes for a simple lift)
- Positioning precision
Mobile crane disadvantages:
- Requires maneuvering space and stabilizers
- Limited by overhead obstacles (electrical cables, trees)
- Weather dependent
3.2 Tower Crane or Mechanical Arm
Fixed tower cranes installed at construction sites can be used if present at the installation site.
Typical applications:
- Installation in buildings under construction or renovation with crane already present
- Lifting inside enclosed courtyards not reachable by mobile crane
3.3 Helicopter
Helicopter lifting is an extreme solution reserved for isolated mountain locations not reachable by land or for installations in very complex contexts.
Helicopter lifting characteristics:
- Useful capacity: 300-2,000 kg depending on helicopter type
- Cost: variable based on flight time.
- Preparation: requires certified takeoff/landing area or exemption
- Weather constraints: perfect conditions mandatory (no wind, no rain, visibility >5 km)
- Authorizations: ENAC, municipality, possibly parks/protected areas
Most frequent applications:
- Alpine huts above 1,500 m
- Mountain facilities without vehicle access
- Island locations without a port
4 Sling Systems
4.1 Types of Straps and Belts
The sling is the system of straps or chains that wraps around the load and connects it to the crane hook. For lifting hot tubs, use exclusively high-tenacity polyester straps.
Metal chains (not recommended for hot tubs):
- Metal chains can damage the external cladding through friction
- If chains must be used, interpose thick protections
4.2 Sling Strap Positioning
Correct strap positioning is fundamental to ensure uniform load distribution and avoid damage to the structure during lifting.
4.3 Anti-Friction Protections
WARNING: At the contact point between strap and hot tub, friction occurs during lifting due to the tension exerted by the strap. To prevent damage to the external cladding, adequate protections must be interposed.
Recommended protections:
- Hard rubber or rigid plastic corner guards positioned on edges
- Corrugated cardboard sheets (10-15 mm thickness) folded along the strap
- Softwood strips (poplar, fir) padded with felt
- Specific sling protections in plastic or rubber material
- Rubber mats 5-10 mm thick wrapped around the strap
Areas to protect with particular attention:
- External cladding edges (maximum tension concentration)
- Vertical contact points of straps on sides (lateral friction)
- Upper edge if straps pass nearby
- Lower edge of cladding panels (more delicate, subject to deformation)
5 Packaging and Protection for Lifting
5.1 Importance of Original Packaging
It is STRONGLY RECOMMENDED to perform lifting with the hot tub still perfectly packaged with the original protections provided by the manufacturer. Original packaging ensures:
- Complete protection of external cladding from scratches, impacts, and friction
- Structural reinforcement provided by the base pallet and side protections
- Uniform load distribution on the sling straps
- Protection of fragile accessories (control panel, thermal cover)
- Dimensional stability during lifting
WARNING: Lifting an unpacked hot tub without original protections significantly increases the risk of damage. If lifting must occur with the hot tub unpacked (e.g., for repositioning after installation), prepare protections equivalent to those of the original packaging.
5.2 Packaging Integrity Check Before Lifting
Before proceeding with lifting, verify:
- Strapping bands intact and properly tensioned (if present)
- Pallet intact
- Protective corner guards present on all edges (if present)
- External film intact without extensive tears
- Total weight compatible with mobile crane and strap capacity
6 Lifting Procedure
6.1 Lifting Area Preparation
- Delimit the lifting area
- Prohibit access to unauthorized persons during all lifting phases
- Verify absence of overhead obstacles along the lifting trajectory
6.2 Slinging Phase
- Completely unroll the lifting straps, checking for absence of damage, cuts, or abrasions
- Position anti-friction protections (corner guards, cardboard, felt) at strap-load contact points
- Pass the straps under the hot tub pallet in the predetermined positions
- Bring the strap ends upward and connect them to the crane hook via shackles or spreader beam
- Verify that straps are equidistant from the load's center of gravity
- Tighten straps, eliminating slack without lifting the load yet
- Visually verify that anti-friction protections have remained in position
6.3 Lifting Phase
- The crane operator activates the winch, SLOWLY lifting the load a few centimeters from the ground (10-20 cm)
- STOP: verify load stability, absence of oscillations, straps correctly positioned
- If the load is unbalanced or straps slip, set it down and correct the position
- When the load is stable, proceed with vertical lifting to the height necessary to clear obstacles
- During lifting, one or two people on the ground guide the load with guy ropes to prevent uncontrolled rotation
- Avoid impacts against walls, trees, electrical cables during horizontal translation
- Once the obstacle is cleared, horizontally translate the load toward the deposit point
- SLOWLY lower the load until it rests on the prepared base
- Set down the hot tub, verifying that support is uniform on all points
- Release strap tension but do not disconnect them until the load is stable
- Verify stability, then unhook the straps from the crane hook
- Remove the straps from under the hot tub
7 Weather Conditions and Operational Constraints
7.1 Acceptable Weather Conditions
Lifting with mobile crane or mechanical equipment can only be performed in favorable weather conditions. It is the operator's responsibility to determine whether to proceed or not, as the successful completion of the operation is under their direct responsibility.
8 Costs and Economic Considerations
8.1 Indicative Mobile Crane Rates
Rates vary based on location, equipment availability, access conditions, and intervention complexity. Always request quotes from multiple mobile crane companies to compare prices and operating procedures.
On average, for a simple lift, the cost has an hourly rate with a minimum billable hours requirement.
For example: 80€+VAT/h with a minimum of 3 billable work hours, therefore the cost will be 240.00€+VAT.
