| Vehicle Dimensions | Measure the longest, widest, tallest, and heaviest vehicles expected to use the platform. | Passenger vehicles commonly vary substantially in length, width, height, and curb weight; include mirrors, roof accessories, and loaded conditions. | Insufficient platform clearance can create collision risks, loading problems, and unsafe operating conditions. | Select capacity and platform dimensions using the largest intended vehicle plus the manufacturer’s required safety clearances. |
| Rated Load Capacity | Confirm the rated load includes the vehicle and any permitted occupants or cargo, as defined by the equipment documentation. | Capacity is specified by the equipment manufacturer and must not be exceeded; it is not determined by vehicle class alone. | Overloading can affect structural components, drive systems, braking, leveling, and emergency safety functions. | Choose a rated capacity with an appropriate engineering margin and display the maximum load clearly at the controls and entrance. |
| Pit, Shaft, and Headroom | Review pit depth, overhead clearance, shaft width, travel height, door openings, and structural tolerances. | Required dimensions vary by platform design, travel distance, rated load, access arrangement, and local construction conditions. | A dimensionally unsuitable building may require costly structural alterations or make installation impractical. | Obtain a site survey and manufacturer layout before finalizing the pit, shaft, openings, or structural design. |
| Foundation and Structural Support | Verify slab thickness, concrete strength, anchor locations, reinforcement, point loads, and load transfer to the building structure. | The required foundation is project-specific and must be based on calculated static, dynamic, impact, and seismic loads where applicable. | A platform must remain stable and aligned under repeated loading and movement. | Have a licensed structural professional review the supporting structure and approve any required modifications. |
| Drive and Power Supply | Compare hydraulic, traction, screw, or other drive arrangements; check voltage, phase, current, ventilation, and emergency power needs. | Electrical requirements depend on motor size, travel speed, duty cycle, building supply, and local electrical rules. | Inadequate power or ventilation can cause nuisance trips, overheating, slow operation, or equipment damage. | Require a coordinated electrical schedule and confirm disconnects, grounding, controls, and backup provisions before installation. |
| Building and Safety Codes | Identify applicable elevator, lift, machinery, electrical, fire, accessibility, and occupational safety requirements. | Requirements differ by country, state, municipality, building use, equipment classification, and installation location. | Code classification affects design, permits, inspections, guarding, doors, emergency systems, and operating procedures. | Consult the authority having jurisdiction before purchasing equipment and obtain written confirmation of the applicable code path. |
| Gates, Doors, and Interlocks | Check landing doors, shaft gates, barriers, door locks, interlocks, edge protection, and protection against unintended movement. | Safety devices must be compatible with the selected equipment and installed according to approved drawings and applicable standards. | Interlocks and guarding help prevent access to hazardous moving areas and operation with an open landing. | Include functional testing of every gate, lock, sensor, and emergency stop in commissioning and periodic inspections. |
| Water, Drainage, and Environmental Exposure | Assess groundwater, rainwater, wash-down water, drainage, corrosion, temperature, humidity, and outdoor exposure. | A pit may require drainage or water-management measures, subject to local building and environmental requirements. | Water and corrosion can damage electrical components, hydraulic equipment, structural parts, and safety devices. | Design drainage and waterproofing early; specify suitable finishes and environmental protection for the installation site. |
| Operating Frequency | Estimate daily cycles, peak-hour demand, expected downtime tolerance, and whether the platform serves private or shared users. | Duty-cycle limits are manufacturer-specific; higher use generally requires more robust components and a planned service program. | A platform designed for occasional use may not be suitable for continuous commercial or residential traffic. | Match the equipment duty rating to actual usage and document peak operating conditions during procurement. |
| Maintenance Access | Confirm safe access to controllers, pumps, cylinders, guides, limit switches, door equipment, and inspection points. | Access clearances and procedures must follow the approved design, manufacturer instructions, and workplace safety requirements. | Poor access increases service time, injury risk, and the likelihood that inspections will be skipped. | Require dedicated maintenance access, isolation points, lighting, and safe working procedures in the installation plan. |
| Preventive Maintenance | Review lubrication, fluid checks, fastener inspection, alignment, corrosion control, sensor testing, and cleaning requirements. | Maintenance intervals depend on equipment design, usage, environment, and the manufacturer’s instructions. | Routine maintenance helps identify wear, leakage, loose hardware, abnormal noise, and safety-system faults before failure. | Create a written maintenance log with dates, findings, corrective actions, technician details, and out-of-service records. |
| Emergency Lowering and Rescue | Check emergency stop functions, manual release procedures, lowering systems, backup power, alarms, communication, and rescue access. | Emergency provisions vary by design and jurisdiction and must be tested by trained personnel. | A documented rescue method reduces risk if the platform stops between levels or during a power interruption. | Provide site-specific emergency procedures, training, signage, and periodic drills where required. |
| Inspection and Certification | Determine acceptance tests, recurring inspections, load tests, documentation, permits, and certification responsibilities. | Inspection frequency and test requirements are established by the applicable jurisdiction and equipment classification. | Operating without required approvals may create legal, insurance, safety, and liability problems. | Assign responsibility for inspections before handover and retain approved drawings, certificates, manuals, and test records. |
| Total Cost of Ownership | Compare purchase, construction, electrical work, permits, inspections, service, replacement parts, energy, and downtime costs. | Lifecycle cost depends on usage, access conditions, local labor, replacement intervals, and required compliance work. | The lowest initial price may result in higher structural, service, energy, or downtime costs later. | Evaluate a multi-year ownership budget and include service response time, spare-parts availability, and training. |
