The 12 ton spider crane from JOJO Machinery, a China exporter selling factory-direct, is built for heavy steel and precast work: a 12.5 t carrier, 19 m of radius, 21 m of lift, a 12 t winch on a 12 mm rope of 120 m and 400 mm tracks. Send the lift list and the access route for a quotation. Steel tracks are 400 mm wide with a 135 mm pitch.
Twelve tonnes is the step for contractors who regularly lift what a ten-tonne machine manages only occasionally. The rating rises, the tracks widen from 300 mm to 400 mm, the rope lengthens to 120 m and the carrier grows to 12.5 t. The extra mass is not decoration: it is what keeps the machine stable when a heavy load swings at 19 m.
Buyers at this level work on steel frames, bridge repairs, precast installation and industrial demolition. Their lifts are planned in advance with certified weights, and their questions are about ground bearing, wind and the load chart rather than about features.
Boom, Winch And The Numbers Behind The Rating
A 5 m base with five sections carries the boom from 5.5 m to 21 m, with 12.3 m of travel in about sixty seconds, luffing 0 to 78 degrees in seventeen and continuous 360 degree slew in forty-two. Hook speed is 10 m/min on a two-speed winch, four-part reeved on a 12 mm rope of 120 m.
Each figure is slower than on the smaller models, and that is the correct trade to make. When the hook is carrying several tonnes, control beats speed, and the hydraulic system is sized so the operator can stop a load dead rather than ride it out.
Outriggers And 400 mm Tracks
Hydraulic telescopic outriggers with hydraulic support spread the machine for the lift, with manual screw-out available where a buyer prefers it. Steel tracks 400 mm wide on a 135 mm pitch over 44 sections carry the 12.5 t carrier at 0 to 2.5 km/h with 25 degrees or 36 percent of gradeability. Folded, the machine measures 6.15 m long, 1.86 m wide and 2.48 m high.

Options And Typical Work
Buyers normally take the torque limiter first, then the radio remote. Cradles and hydraulic fly jibs are also available, and paint can be matched to six fleet colours. Typical work: steel frames on low-rise buildings, bridge and culvert repairs, precast panels and stair flights, plant installation, and demolition where the machine lifts rather than drags.
FAQ
Q: What does the 12 ton spider crane lift at 19 m? A: The chart figure for that radius, which is a fraction of the rating. We verify the heaviest planned pick before the machine is quoted.
Q: Do you provide lift plans? A: We provide the load chart, outrigger loadings and lifting points. The lift plan itself is prepared by the contractor with those figures, as required by local regulation.
Q: How is it transported? A: At 12.5 t and 6.15 m folded it needs a low-loader or a 40-foot container, and it tracks off a ramp under its own power at the destination.
Q: Is remote control recommended? A: Yes on this size. At 19 m of radius the operator cannot see the load and the outriggers at once, and the remote solves that.
Q: Lead time and payment terms? A: Four to five weeks for the standard configuration, longer where the boom or winch is customised. Deposits run 30 percent on signing, the remainder on shipping documents, by bank transfer or letter of credit.
