The JTZD‑12T spider crane is our mid‑range unit engineered for tighter confined‑space layouts than 16‑ton spider crane models, featuring 12‑ton rated lifting capacity and a 1.86‑meter transport‑width chassis. Suited for small industrial workshops, narrow‑corridor buildings, medium‑scale renovation projects and zones where 16‑ton units cannot operate due to wider body dimensions. Equipped with a Yunnei 76kW engine with verified 6‑8 L/h fuel consumption (on‑site test data), low‑noise hydraulic system and agile deployment, it delivers lifting performance for scenarios with stricter spatial constraints than higher‑tonnage cranes.

Core differentiation from the JTZD‑16T: its 1.86‑meter width enables entry to narrow corridors, small workshops and 1.8‑2.0‑meter doorways, zones where the wider 2.13‑meter 16‑ton unit cannot maneuver. It provides a viable solution for construction sites with strict spatial limitations.
Designed for medium‑scale lifting tasks that do not require the high power of 16‑ton units, it combines 12‑ton load capacity with a 6.8‑ton operating weight, delivering agile performance for workshop maintenance, light‑duty equipment installation and commercial premise renovation.
The industrial‑grade Yunnei engine is optimized for verified 6‑8 L/h fuel consumption (on‑site test data) and low noise emission, suited for occupied workshops and buildings with strict noise regulations. Its simplified maintenance structure reduces long‑term operational costs.
The compact hydraulic system enables full outrigger deployment and retraction within 6 minutes (on‑site test data), ideal for short‑term renovation projects and workshop maintenance requiring fast setup efficiency.
Its lightweight build (23% lighter than the JTZD‑16T) cuts transportation expenses, allowing transit via smaller flatbed trucks without additional permit requirements. It matches operational needs of contractors with light‑duty transport fleets.
Independently adjustable outriggers adapt to uneven ground commonly found in industrial workshops and renovation sites. It maintains full operational stability on unlevel surfaces without extensive ground preparation work.
