Onchtech · Indoor Complex Space Lifting Solutions

High‑precision Indoor Lifting Solutions for Commercial Complexes and Transportation Hubs

For commercial complex atriums, airport terminals, high‑speed rail stations, high‑rise building interiors, and high‑cleanliness production environments, Onchtech uses narrow‑body tracked spider cranes, dual power (diesel/electric), low‑ground‑pressure tracks, and precision lifting accessories to solve challenges such as large equipment access difficulties, finished floor protection, indoor exhaust and noise restrictions, and high‑precision installation of glass curtain walls, steel structures, and equipment.

Core Lifting Challenges in Indoor Environments

Lifting operations in commercial buildings, transportation hubs and high‑cleanliness indoor spaces are not only about capacity – they also require simultaneous solutions for equipment access, finished surface protection, indoor power conditions, and high‑altitude precision positioning.

Equipment Cannot Easily Reach the Work Area

Factory cranes or large wheeled cranes often cannot cover indoor blind spots, while doorways, corridors, passenger lifts and floor passages limit large equipment entry – the lifting device must have more compact folded dimensions.

High Demands for Finished Floor Bearing and Protection

Marble, ceramic tiles, epoxy floors and floor slabs are sensitive to point loads and turning friction of equipment – both machine movement and outrigger deployment need controlled ground pressure and appropriate load‑spreading measures.

Strict Indoor Environment and Precision Installation

Commercial buildings and clean production environments may limit exhaust emissions and noise, while curtain wall glass, special steel structures and overhead equipment also require smoother, more controllable fine‑lifting capability.

Onchtech High‑precision Indoor Lifting Solutions

The solution revolves around four core goals: "enter the site, protect the floor, operate indoors, lift with precision". The spider crane is folded to a compact size to pass through doorways, corridors or service lifts to reach the work area, then the outriggers are deployed to establish a stable working base. Wireless remote control, hydraulic fly jib and specialised lifting attachments enable component hoisting, obstacle clearance and accurate positioning.

Narrow‑body Access to Confined Spaces

The 1.5‑ton model has a folded width as low as 0.65m, while the 3‑ton model is 0.80m – both can pass through standard doorways, indoor corridors, service lifts and tight turning areas, bringing the crane closer to the installation point.

Tracked Mobility and Finished‑Floor Protection

Engineering rubber tracks help distribute the machine weight and non‑marking tracks are available on request. Together with load‑spreading plates and careful travel/outrigger placement, they reduce the risk of damage to marble, ceramic and epoxy surfaces during construction.

Low‑Emission Indoor Power

The 3‑ton model offers a diesel engine plus AC380V electric dual‑power configuration, capable of outdoor transport and indoor work. When on‑site mains power is available, the electric mode can be selected to reduce exhaust emissions and operating noise in enclosed spaces.

Wireless Control and Precision Positioning

Wireless remote control allows the operator to choose the best viewpoint for observing the load, while fine‑motion control reduces shock during lifting, slewing and derricking, improving the controllability of positioning glass, steelwork and equipment.

Hydraulic Fly Jib and Specialised Lifting Gear

For eaves, beams, suspended ceilings and deep installation positions, a hydraulic fly jib can be optionally equipped to enhance obstacle‑clearing and complex‑angle capability. For glass curtain wall work, suction cups matched to glass sizes are available to improve the handling and positioning of large panels.

Typical Application Scenarios

Commercial Complexes and Atriums

Suitable for high‑level curtain wall glazing, large shopfront glass, art chandeliers, decorative steel structures and top‑level component installation.

Airport Terminals

Suitable for terminal glass curtain walls, skylight components, indoor steel structures and overhead equipment installation.

High‑speed Rail Stations and Transport Hubs

Suitable for concourse curtain walls, overhead steelwork, large decorative elements and equipment component lifting.

High‑rise Interiors and Clean Factories

Suitable for moving, installing and maintaining equipment, steel structures, glass components and precision production machinery inside floors.

Recommended Equipment and Selection

Based on access width, load weight, lifting height and working radius, this solution can be primarily matched with the 1.5‑ton compact model or the 3‑ton dual‑power tracked spider crane.

Feature 1.5‑ton Compact Spider Crane 3‑ton Dual‑power Spider Crane
Positioning Ultra‑narrow space agile model Main workhorse for indoor heights
Max. rated capacity 1.5 t 3.0 t
Max. lifting height 6.5 m 10.8 m
Max. working radius 6.0 m 10.0 m
Folded dimensions 2.50 m × 0.65 m × 1.50 m 3.50 m × 0.80 m × 1.85 m
Machine weight 1.7 t 2.7 t
Power configuration Honda gasoline engine (customisable) Changchai 14.7 kW diesel + AC380V electric dual power (customisable engine)
Recommended use Narrow doorways, lifts, lightweight curtain wall and indoor equipment installation Curtain wall glass, steel structures and mid‑/high‑level precision lifting

Prefer the 1.5‑ton Compact Model

When doorway, service lift and internal passage widths are the primary constraints, the load is relatively light, and height/radius requirements are modest, choose the 0.65m narrow‑body model.

Prefer the 3‑ton Dual‑power Model

When the project requires greater lifting height, larger horizontal radius, or the ability to switch between outdoor engine transport and indoor AC380V electric operation, choose the 3‑ton dual‑power model.

Selection note: Actual equipment configuration should be determined by combining load weight and dimensions, target installation height, working radius, narrowest passage size, lift rated capacity, floor/ground bearing capacity, outrigger deployment space and on‑site power availability. Maximum rated capacity, height and radius are boundary parameters; actual lifting capability must be verified against the load chart for the specific working condition.

Project Value

Reduces Equipment Access Difficulty Use compact folded dimensions to pass through existing doorways, corridors and service lifts, reducing the need for temporary demolition and large external crane logistics.
Lowers Risk of Finished Floor Damage The tracked undercarriage, non‑marking tracks and sensible load‑spreading solutions are better suited for marble, ceramic and epoxy surfaces in already finished areas.
Suits Indoor Working Conditions Electric or dual‑power configurations help reduce exhaust and noise, making them suitable for enclosed or environmentally sensitive worksites.
Improves Installation Positioning Control Wireless remote control, fine‑motion functions, fly jib and specialised attachments help crews adjust glass, steel and equipment installation attitudes more stably.

Implementation and Safety Essentials

Indoor lifting requires combining machine parameters with the actual construction environment. Before equipment transport and formal lifting, key points to verify include access conditions, floor bearing capacity, machine working condition and lifting gear compatibility.

Route Verification Check doorways, corridors, turning areas, lift dimensions, rated load and overhead clearance along the route.
Floor Bearing Capacity Verify that the floor slab or ground can withstand travel loads and outrigger reactions, and arrange load‑spreading protection accordingly.
Working Condition and Rigging Check Consult the load chart for the actual boom length, radius, load weight and outrigger status, and ensure suction cups, slings and connectors match the load.
Work Zone Management Clearly define the swing, load‑movement and outrigger zones, and choose the appropriate power mode and site organisation plan.
