Frequently Asked Questions about Products
Onchtech explains that spider cranes feature a compact body and crawler mobility for indoor, confined, and complex lifting sites, while truck cranes are generally suited to locations with better road access and more open working space. Selection should consider load, lifting radius, ground conditions, and site access.

Spider cranes and truck cranes differ primarily in their equipment form, site access characteristics, and typical operating environments. A spider crane, also known as a mini crawler crane, has a compact body and crawler mobility that can support lifting work in indoor, confined, and complex sites. A truck crane is generally more suitable for locations with better road conditions and more open working space.

Spider Crane: Compact Access for Restricted Sites

The compact structure and crawler-based mobility of a spider crane can make it suitable for indoor lifting, narrow spaces, and sites with more complex access conditions. These characteristics are relevant where available operating space is limited or where site entry and movement require closer consideration.

Truck Crane: More Suitable for Open Work Areas

A truck crane is generally suited to work locations with better road access and more open operating areas. Where site conditions provide sufficient space for vehicle access and lifting operations, a truck crane may be an appropriate equipment category to consider.

Key Factors for Equipment Selection

The final selection between a spider crane and a truck crane should be confirmed according to the specific project conditions, including:

  • Load requirements: the lifting load to be handled;
  • Lifting radius: the required working distance for the lift;
  • Ground conditions: the conditions of the operating surface; and
  • Site entry access: the available route and space for equipment entry and movement.

Onchtech, the engineering machinery brand of Hunan Hongchang Machinery Co., Ltd., supports B2B cooperation in engineering machinery manufacturing and customized collaboration. For a specific lifting project, the applicable equipment type should be further confirmed based on the actual load, lifting radius, ground conditions, and site access requirements.
