Palletizing is the kind of task that seems fine to do manually until volume climbs — then it becomes the visible bottleneck at the very end of your line, where a bag, pail, or carton that took seconds to produce sits waiting for someone to stack it correctly onto a pallet before it can move to dispatch.

Where Manual Palletizing Breaks Down

Throughput caps out at human stacking speed. However fast your filling and packing lines run, if the last step is manual stacking, that's your real line speed — not the equipment upstream.

Repetitive lifting is a real injury risk. Palletizing involves repeated lifting and twisting motion for an entire shift. As volumes grow, that's more exposure, more strain injury risk, and — practically — a harder role to keep staffed.

Stack quality varies by operator and fatigue. A consistent, stable pallet pattern matters for transport safety and warehouse storage — manual stacking quality drifts over a shift as fatigue sets in, in a way automated palletizing doesn't.

Labour cost scales linearly with volume in a way automation doesn't. More output means more palletizing labour hours, indefinitely — automating the step converts that into a fixed capital cost instead.

Where a Palletizer System Fits

ENZAC supplies two palletizer configurations, each suited to a different production profile. A high-level palletizer runs at up to 40 bags per minute, handling up to 180 kg payload including gripper arm, across bags, pails, gallons, pallets, carton boxes, and tins — with a programmable layer pattern and gripper customised to your specific product. This configuration suits a dedicated, high-speed single-product line where consistent, repeatable palletizing at volume is the priority.

A gantry palletizer handles up to 300 kg payload (including gripper arm) and covers a broader application range — palletizing, de-palletizing, cartoning, and pallet handling across bags, pails, gallons, pallets, carton boxes, tins, drums, tyres, and solar panels. Gantry systems can serve multiple bagging or filling lines from a single station, and are built on configurable robot platforms (ABB, FANUC, FUJI, KUKA) with a gripper customised to your product mix. This configuration suits multi-line or irregular product handling where flexibility matters more than dedicated single-line speed.

Both types are built with pallet compatibility across wood, plastic, and metal — standard and custom sizes — and programmable layer patterns to match your product's stacking and stability requirements.

Choosing Between the Two Isn't Just About Speed

The real decision factor isn't simply "how fast" but whether your operation is a dedicated single-product line (favouring high-level) or a facility running multiple products or lines through a shared end-of-line station (favouring gantry). Getting this wrong means either paying for flexibility you don't need, or under-provisioning for a multi-line reality.
