Tracked Sprayers for Greenhouse Aisles

Greenhouses impose hard dimensional limits: doors, benches, beds, pipes and crop growth can all reduce the usable aisle. Ventilation and worker separation add operating constraints. A tracked remote boom sprayer therefore starts with a clearance survey and an approved chemical-handling plan before tank size or options are discussed.

Measure the complete working route

Measure every door, threshold, aisle and turning pocket along the complete route. Include crop growth into the aisle, suspended pipes, irrigation lines, floor drains and gradients. Record ventilation controls, occupied periods, wash-down location, boom height and the required nozzle arrangement.

Model shortlist for planning

All currently published RCS models use a 200 m remote-control range. Model coding uses Boom -B for this application. Final engine, pump, fan or boom, nozzle and plumbing specifications are confirmed for the order.

Tank size is a work-cycle decision

Calculate tank demand from the approved application volume and the area or row length treated between refills. Then test that capacity against the narrowest passage, turning space, ground, transport and refill route. A smaller machine can be the better commercial choice when it reduces access conflicts or can refill quickly.

Operating workflow

1. Confirm the label permits the greenhouse crop and establish ventilation, re-entry and emergency procedures.
2. Walk the complete route and mark doors, drains, pipes, workers and sensitive production zones.
3. Set and calibrate boom height, nozzles, pressure and speed for the bed or bench arrangement.
4. Control access and maintain sight of the sprayer throughout each aisle pass.
5. Handle remaining liquid and clean the equipment only at the approved location.

Limits and safety boundaries

A remote controller does not make an enclosed-space application safe by itself. Ventilation, exposure control, re-entry time, spill response and the product label remain decisive. Confirm all dimensions with the crop at its treatment-stage size.

Remote operation changes the operator position; it does not remove pesticide training, protective equipment, drift control, exclusion zones, re-entry rules, machine inspection or emergency planning.

Greenhouse-specific question: the real clearance envelope

The usable aisle is the smallest moving envelope along the entire path. Door frames, heating pipes, bench corners, crop trolleys and leaves can reduce it below the building drawing. Measure width at track level, tank level and boom level, then add working clearance rather than specifying a machine exactly equal to the opening. Check thresholds and drains that can change machine pitch as it passes through a doorway.

Turning should be demonstrated on the tightest end bay with the crop at treatment-stage size. If the machine cannot reverse or turn without entering a bench, the work plan may require one-way aisles or a compact configuration. Confirm whether the boom stays deployed, folds or needs a custom height. These layout decisions should be settled before tank capacity is increased.

Ventilation, occupancy and wash-down

An enclosed structure needs a documented sequence for ventilation shutdown or operation, worker evacuation, application, re-entry and cleaning. Remote control does not authorize the operator to remain in an exposure zone. Identify where the operator can keep sight of the machine without blocking doors and where emergency access remains available. Remaining liquid and wash water must follow the farm’s approved procedure; floor drains are not automatically an acceptable disposal route.
