Onchtech 1.2–4 t spider cranes use 180–230 mm rubber tracks to help protect indoor tiles and epoxy floors. The 10–16 t models use 300–400 mm industrial steel tracks for muddy and gravel terrain, with a stated climbing capability of 25°.

Onchtech spider cranes feature a digital load moment limiter that monitors load weight, working radius, boom angle and outrigger status in real time, automatically disabling hazardous movements when an overload is detected.

Onchtech spider cranes from 1.2 t to 16 t feature a dual-power system with a diesel engine and AC 380V electric motor, enabling zero-emission operation when connected to on-site mains power.

Onchtech spider crane equipment is equipped with a digital moment limiter that monitors load weight, radius, boom angle, and outrigger status in real time, automatically cutting off hazardous movements during overload.

Onchtech recommends daily lubrication of the slewing bearing, boom slide blocks and pins with molybdenum disulfide extreme-pressure grease; grease the telescopic boom when extended, change SI 10W-30 engine oil every 100 working hours, check CKC220 gearbox oil, and inspect the turntable and boom every 20 days.
