Spider cranes are compact mobile lifting machines specifically designed to operate in tight or hard-to-access spaces where traditional cranes cannot. Recognizable by their spider-like legs (outriggers) which extend outward for stability, these cranes combine portability, power, and precision - making them suitable for urban sites, indoor facilities, rooftops and uneven terrain environments.

1. Compact and Foldable

Spider cranes are compact enough to pass through standard doorways or passageways when folded, and some models may even measure less than 80 cm (31 inches).

2. Spider-Like Outriggers

These outriggers feature two sets of legs extending in all directions like spider legs for safe lifting on uneven or soft surfaces.

3. High Lifting Capacity in a Compact Size

Despite their compact size, spider cranes often boast lifting capacities between 500 kg to 10,000 kg (0.5 to 10 tons), often up to 20-25 meters (65-82 feet).

4. Remote Control Operation

Most modern spider cranes feature wireless or tethered remote controls to allow operators to safely monitor movement and lifting from a safe distance.

5. Multiple Power Options

Electric-powered: Ideal for indoor use (quiet and emission-free).

Diesel power systems: Ideal for outdoor and heavy-duty applications.

Hybrid models: Versatile solutions suitable for all environments

All Major Components of a Spider Crane

1. Power System

Diesel Engine

Powers the hydraulic system for outdoor and heavy-duty use

Brands: Yanmar, Kubota, etc.

Electric Motor

Quiet and emission-free for indoor use

Often AC (230V/400V) or DC battery-powered

Hybrid System

Combines diesel + electric for versatile environments

Generator / Battery Pack

Supplies power to motor or auxiliary functions

Battery packs are often lithium-ion

2. Lifting System

Spider Crane Applications

1. Construction

Spider cranes are ideal for tight access construction sites located within dense urban environments where space is at a premium and traditional cranes would not be feasible.

Use Cases: Wrecking steel beams or prefabricated panels onto rooftops

Lifting heavy tools or rebar onto upper floors of a high-rise.

Material handling through alleyways or courtyards that are inaccessible to truck cranes requires precision.

Work on top of buildings without tower crane access where tower cranes cannot be installed is necessary.

2. Glass Installation (Facade, Curtain Wall & Skylight Systems)

Modern buildings often include large glass panels. Spider cranes offer an efficient way of handling and placing this material - especially with optional vacuum lifter attachments.

Use Cases: Wrought iron curtain walls can be installed in office buildings or high-end residential properties for use as protection from intruders and weather elements.

Installing skylights and domes on rooftops requires lifting and placing skylights or glass domes carefully.

Replacing damaged panels during renovations without altering the entire facade

Working in atriums, malls or airports without damaging interior flooring is no small task.

3. Power Plant Maintenance (Nuclear, Thermal and Hydroelectric)

Maintenance in energy infrastructure often necessitates moving heavy machinery in tight and hazardous spaces; spider cranes offer an efficient lifting solution in these difficult settings.

Use Cases: [Install or Uninstall Motors, Turbines and Switchgear].

Maneuvering generators or pressure vessels in tight substation rooms is no simple task.

Working safely in radiation-controlled zones using remote operation for safety.

Perform shutdown maintenance when time and precision are essential.

4. Indoor Facility Work (Shopping Malls, Museums, Airports and Hotels)

When noise and emission concerns are of concern in public or enclosed spaces such as shopping malls or museums, electric spider cranes offer a quiet alternative for material handling or renovation tasks in these environments.

Use Cases: : For installation of large sculptures or display units into museums or galleries

Lifting air conditioning or HVAC units onto mezzanines or ceilings.

Renovating malls or hotel lobbies without altering decorative elements.

Moving safes, escalator parts or large furniture pieces.

5. Shipping Yards and Logistics Centers

Port operations and warehouses often entail high-frequency lifting of containers, engines and cargo in limited spaces. Spider cranes offer agility with their high capacity in a compact frame design.

Use Cases: Lifting heavy cargoes or palletized machinery into overcrowded container yards is often an uphill battle.

Perform equipment swaps in large logistics centers or warehouses

Unloading items from trucks and ships that do not have permanent crane systems requires unloading the items using temporary solutions such as trolleys.

Installation of conveyor belts or loading dock equipment

6. Tree Removal and Landscaping

Spider cranes provide safe tree lifting, trimming and removal in areas with difficult ground conditions or limited access for larger machinery.

Lifting Tree Trunks or Large Branch over Building or Fence

Assist arborists in trimming high limbs in tight gardens or yards.

Installing large garden ornaments, fountains or boulders requires professional expertise.

Working on uneven or muddy ground without damaging lawns

Choosing the Right Spider Crane

Load capacity

Boom length & height

Fuel type (electric vs diesel vs hybrid)

Dimensions (width, height folded)

Ground surface compatibility

Operator training needs
