• SPYDERCRANE’s Overturn Protection System is a patented UNIC exclusive safety system that is included on the SPYDERCRANE URW090 Series, URW200 Series, and some URW300 Series models.

The Overturn Protection System is comprised of an on-board computer system that continually measures ground pressure on each outrigger through an incorporated “load cell” in each outrigger. If during a lift, one outrigger starts to lose ground pressure and is nearing the safe operating limits of the crane, an alarm will sound and the SPYDERCRANE mini-crawler crane will start to slow the crane functions. If two outriggers start to loose ground pressure, the mini crane will automatically stop all functions that would put the crane closer to an unsafe configuration. With the alarms sounding and the crane stopped, the operator will now be able to maneuver the crane back into a favorable operating position to continue the lift.

• Variable Geometry Outriggers allow for lifts in tight spaces. A standard feature on the 090 and 200 Series SPYDERCRANE models, by offering numerous locking positions on the outrigger swing, knee, and inner box joints, the SPYDERCRANE mini crane can set up around an obstacle, on a catwalk, or in a machinery room in very limited spaces.

• Unlike most cranes on the market, SPYDERCRANE mini cranes offers pressure sensitive controls that speed or slow crane functions based on the amount of pressure input by the operator. Most SPYDERCRANE mini cranes are also equipped with a wireless remote control so an operator can position themselves into the best vantage point for their lift. These features make the SPYDERCRANE branded mini crane one of the easiest mini cranes to operate.
