what a spider crane is？
This machine is the best choice for modern construction, maintenance and tight access work.
“When big cranes can’t reach, spider cranes go where no others can.”
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
Telescopic Boom (Main Arm)
Usually 4–6 sections for vertical & horizontal reach
Material: High-strength steel or aluminum alloy
Jib (Optional Extension)
Articulated or fixed extension of the boom
Used for additional reach or angled lifts
Winch System
Lifting hook and steel wire rope mechanism
Motor-driven, supports variable lifting speeds
includes upper/lower limit sensors
Hook Block & Pulley System
Distributes weight and allows for multi-part reeving
Often rated for specific load capacities
3. Control System
Remote Control (Radio or Wired)
Joysticks or buttons for boom, winch, rotation, etc.
Emergency stop & display panel for feedback
Onboard Control Panel
Manual backup system for crane operation
May include digital load monitoring and diagnostics
Load Moment Indicator (LMI)
Safety system that prevents overloading
Measures boom angle, length, load weight
4. Stabilizing System
Spider-Leg Outriggers (Hydraulic or Manual)
Extendable legs for 360° stability
Independent angle and length adjustment
5. Mobility & Chassis
Crawler Tracks (Rubber or Steel)
Self-propelled movement over rough terrain
Zero-tail swing for tight turning radius
Travel Motors & Planetary Gearbox
Provide driving torque to the tracks
Often 2-speed for fast/precise movement
6. Structural & Safety Components
Chassis Frame
Central load-bearing structure
Mounts all crane subsystems
Counterweights (if applicable)
Enhances lifting stability
Fixed or removable, depending on model
Limit Switches & Sensors
Prevent overextension or collision
Critical for boom, winch, outrigger systems
Safety Alarm & Emergency Stop
Sound/visual warnings during risky operations
Spider Crane Specific parameters
Detailed parameters for different loads are as follows:
2-3 Ton spider crane parameters
10-12 Ton spider crane parameters
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
