A mini crawler spider crane is a compact lifting machine designed for construction sites where access and working space are limited. YG offers 3 ton, 5 ton, and 8 ton models with five section telescopic booms, hydraulic crawler travel, and independently adjustable outriggers. Buyers can choose diesel or electric power according to their project requirements, with remote control available as an option. Whether you need to lift equipment indoors or handle materials on a restricted jobsite, YG can help you select a suitable configuration.

| Wire rope diameter and length | 8 mm × 45 m | 11 mm × 80 m | 11 mm × 80 m |
| Travel drive | Hydraulic motor | Hydraulic motor | Hydraulic motor |
| Travel speed | 0 to 2.5 km/h | 0 to 2.5 km/h | 0 to 2.5 km/h |
| Transport dimensions, L × W × H | 2950 × 980 × 1560 mm | 5000 × 1500 × 1900 mm | 5000 × 1600 × 2180 mm |
| Machine weight | 2700 kg | 6200 kg | To be confirmed |
The maximum working radius and lifting height are not equivalent to the maximum rated load. The load that a crane can safely lift changes with boom position and working radius. Ask YG for the applicable load chart before making a final selection.

What Makes the YG Small Spider Crane Different?
The most useful way to evaluate a mini crawler spider crane is to look beyond its rated tonnage. Boom construction, transport dimensions, power options, and outrigger arrangements all affect whether a machine suits a particular site.
Five Section Pentagonal Telescopic Boom
All three YG models use a five section telescopic boom with a pentagonal structure. The YG 3t model has a listed boom length of 3.1 to 9.2 m, with a stated extension time of 20 seconds. The YG 5t and YG 8t specifications list a 12.3 m boom length and a 54 second extension time.
This design allows the operator to adjust the boom reach for different lifting positions. Before ordering, confirm the maximum boom length and extension specifications for your chosen model, as well as the corresponding load chart.
Hydraulic Crawler Travel
The YG spider crawler crane uses hydraulic motors for travel, with a listed speed range of 0 to 2.5 km/h. Its crawler chassis helps the machine move around the jobsite without relying on a separate vehicle for every short repositioning task.
However, crawler travel does not mean the crane can safely cross every surface. Ground bearing capacity, slopes, floor protection, and access routes should be checked before the machine enters the site.
Independently Adjustable Outriggers
The independently adjustable outriggers help the operator position the crane for lifting on suitable ground conditions. This is particularly relevant when a work area has limited space or an irregular layout.
The required outrigger footprint still needs to be checked. Buyers should confirm the actual extension range, allowable ground conditions, and required support pads before using the crane on a project.
Diesel or Electric Power Options
YG offers diesel and electric power configurations. The right choice depends on the work environment rather than lifting capacity alone.
An electric configuration may be preferable for indoor projects where exhaust emissions are a concern, provided the selected power system meets the site’s requirements. A diesel configuration may suit outdoor jobs where electrical access is limited.
Confirm the available power specifications, operating requirements, and configuration for the selected model when requesting a quotation.
Ask About Diesel and Electric Configurations
Tell YG whether your crane will work indoors, outdoors, or in both environments so the appropriate power option can be discussed.

Where Can a Mini Crawler Spider Crane Be Used?
A small tracked crane is worth considering when a conventional crane is difficult to position or when lifting work must take place within a restricted footprint.
Indoor equipment installation: The compact YG 3t transport width of 980 mm may be relevant for projects with narrow entrances. Measure the complete access route, including doorways, turns, and overhead clearance, before confirming suitability.
Glass and curtain wall installation: Telescopic boom movement and continuous slewing help position loads around building facades. The required lifting capacity must be checked at the actual working radius.
Factory maintenance: A spider crane can be considered for lifting motors, machinery components, and other equipment during maintenance work. Check floor loading limits and the space needed to deploy the outriggers.
Steel structure installation: The 5t and 8t models provide larger listed working ranges and lifting heights than the 3t model. Their suitability depends on the load weight, installation height, and required reach.
Building renovation: A small spider crane may help move materials through restricted construction areas. For low ceiling projects, check the machine’s overall height, boom movement envelope, and available overhead clearance.

How to Choose Between the YG 3t, 5t, and 8t Models
Choosing a mini crawler spider crane by tonnage alone can lead to the wrong purchase. Use these checks before comparing quotations.
1. Confirm the Load at the Required Radius
Write down the heaviest load, the distance from the crane’s slewing center to the load, and the required lifting height. These three figures form the starting point for model selection.
For example, the YG 3t specification lists a maximum working radius of 8.83 m with a load value of 0.15 t. This illustrates why the 3 ton capacity class should not be interpreted as a 3 ton lifting capacity at every radius.
2. Measure the Transport Route
The listed transport widths are 980 mm for YG 3t, 1500 mm for YG 5t, and 1600 mm for YG 8t. If the crane must pass through a doorway, these measurements are useful for initial screening.
Also check the machine’s transport length and height. Allow additional clearance for turns, ramps, and site handling, and confirm whether any components need to be removed for transport.
3. Check the Setup Area
Measure the available area for outrigger deployment, not just the space occupied by the crawler chassis. Confirm floor load limits, support conditions, and nearby obstacles before selecting a machine for indoor work.
4. Confirm the Operating Configuration
Discuss diesel or electric power, manual operation, and the optional remote control with YG. Ask which configuration is available for your selected model and what is included in the quotation.

What Should You Confirm Before Ordering a Small Spider Crawler Crane?
Before placing an order, ask the manufacturer to confirm the following details in writing.
- The rated load chart for your required boom length and working radius.
- The maximum boom length and the conditions used to measure lifting height.
- The complete transport dimensions and machine weight.
- The diesel or electric power configuration and operating requirements.
- The outrigger deployment dimensions and ground support requirements.
- Whether remote control is included or supplied as an option.
- Available spare parts, maintenance guidance, and after sales support.
These checks make quotations easier to compare. They also help prevent a common purchasing mistake: selecting a crane that meets the lifting capacity requirement but cannot access or operate properly at the intended site.
Why Choose YG for a Mini Crawler Spider Crane?
YG offers three standard models covering the 3 ton, 5 ton, and 8 ton capacity classes. Their shared five section pentagonal boom design and hydraulic crawler travel provide a consistent starting point for comparing the range, while differences in working dimensions help buyers narrow down the right machine.
YG also offers diesel and electric power options, optional remote control, and configurable equipment arrangements. Buyers can discuss their lifting requirements and site limitations with the manufacturer before confirming a configuration.
Rather than choosing solely by the largest advertised tonnage, provide YG with the load chart requirements, transport restrictions, and operating environment. This gives both sides a clearer basis for confirming the machine specification.
