Fabrication shop sheet metal storage rack
The heart is a dry-running, oil-free rotary vane pump driven by 380-440 V, 50/60 Hz single-phase supply. It pulls a clean -85 kPa and stores the reserve in a three-litre tank, so even if someone kicks the mains cable the plate stays locked for a full five-minute coffee break. Pneumatic logic valves switch the circuit—vacuum on, hold, release—so there is no solenoid to stick, no PCB to fry, no summer heatwave to fear. For sites already fed by a 6 bar compressor the same beam can be specified with a venturi cartridge; unplug the motor, screw in the air line, and the lifter keeps working while the electrician is still looking for his screwdriver.

A single operator walks up to a three-ton stack of laser-grade steel, touches a handle, and in the next breath a two-metre panel glides onto the cutting table—no gloves burned on hot slag, no shouting for a second forklift, no scarred edges from C-clamps. That quiet moment is the Herochu pneumatic vacuum lifter doing what it was engineered to do: turn brute weight into fingertip work without asking the workshop to rewire the ceiling or buy a bigger crane.

Eight or ten suction cups lock to cross-slots on an aluminium extrusion that moves in X and Y. Slide the cups inward and the same frame will pick a 1 250 mm square remnant; slide them outward and it swallows a 4 000 mm skin without adding weight. Cup diameter steps from 200 mm on 300 kg panels to 250 mm on the one-tonner, so thin 8 mm aluminium will not oil-can and heavy 20 mm plate will not sag. Each cup line has its own vacuum sensor: drop below -60 kPa and an amber beacon flashes, the hoist circuit locks, and a 92 dB buzzer reminds everyone to stand clear until pressure rebuilds. Hit the mushroom button and the circuit flips to atmospheric release—plate down, job done, no violent jerk.
The beam itself is a welded box of 5 mm steel skinned with 2 mm aluminium chequer plate to keep mass low. Total weight for a 3 m two-cup beam is 38 kg, so two technicians can shoulder it up a ladder and bolt it to an existing overhead rail in twenty minutes. A bottom-mounted handle pivots 360° on a sealed bearing; the operator can spin the plate to align the grain while walking, elbows never above shoulder height. Ergonomics audits on a three-shift site showed a 28 % drop in reported wrist strain in the first month.
Four stock models cover most laser and plasma tables. The HC-PR3015-300 lifts 300 kg sheets up to 3 m long and 8 mm thick; the HC-PR4020-1000 moves one-ton, 20 mm plate across a 4 m span without growing the outer dimensions. Need to flip the load vertical for edge deburring? Add a 90° powered tilt module driven by a planetary gearbox and pneumatic brake. The rotation locks at any angle, so you can present the plate to a roller table, deburring machine or stillage without a second operator steadying the edge.
Installation is deliberately plug-and-play. A single cable with an industrial CEE plug feeds the on-board inverter; no control cabinet, no star-delta contactors, no programming laptop. Compressed-air models ship with a self-draining filter regulator and a quick-connect Euro coupling—hook up, adjust 6 bar, lift. Every lifter leaves the Jiangsu plant with a full test dossier: 1.5 × rated load held for thirty minutes, leak-down under 2 % per minute, insulation resistance > 100 MΩ. The paperwork travels in the crate so your insurer and ISO auditor tick their boxes before the shrink-wrap hits the skip.
Return on investment arrives faster than the delivery truck. A job shop feeding a 6 kW laser reported an average 3.9 min per sheet using magnets and slings—walk, shim, de-burr where the magnet scarred the edge. With the Herochu vacuum beam the same operator lowered the crane, touched the toggle, lifted and positioned in 42 s. At seventy sheets per day the saving is 4.1 labour hours daily; capital cost is recouped in nine weeks before counting fewer scratches, less edge deformation and the ability to run thinner protective film that used to tear under magnetic claws.
Custom builds are routine. Add a second beam for tandem lifts of composite sandwich panels, specify food-grade blue cups for brushed stainless in a brewery, or request radio remote so the rig can hang from a mobile boom and feed roof sheets three stories up. We keep blank extrusion in stock; unusual lengths ship in five days, not five weeks. Spare parts—cups, filters, sensors—are stocked in Rotterdam, Houston and Dubai for 72-hour delivery, and every component is tool-free replaceable on the shop floor.
Email the longest plate you handle, the thickest and the weight. Within one working day you receive a 3-D drawing, vacuum calculation and freight cost. Approve the design, pay a 30 % deposit and the lifter ships in seven days, ready to cut your handling time in half before the next shift change.
