The 1930 × 660 mm surface accommodates adult patients with a margin that reduces edge proximity during transport — a practical safety consideration on longer transfer routes through hospital corridors. The crank height adjustment mechanism offers a reliable, maintenance-friendly alternative to hydraulic systems. Operated by a hand crank at the foot end, the mechanism provides smooth, controlled elevation across the 510–850 mm range, with each turn producing a predictable and proportional height increment. This predictability is particularly useful during bed-height alignment transfers, where overshoot in either direction requires readjustment. Backrest adjustment to 70° enables the KL-PT004 to accommodate patients from fully recumbent through to a substantially elevated position that reduces aspiration risk in post-operative and respiratory patients. Foldable side rails raise and lock securely during transport, preventing patient roll-out without restricting clinical access from either end during en-route observation or intervention. The medical casters provide smooth, responsive movement with brake control that engages with a single foot pedal action. ## Key Features - **Wider 660 mm platform** — 660 mm width provides greater patient surface margin than standard 600 mm trolleys. - **0–70° adjustable backrest** — crank-operated backrest adjustment for patient positioning from flat to substantially semi-upright. - **510–850 mm height adjustment** — 340 mm range via manual crank for bed-height alignment during patient handover. - **Foldable side rails** — protective rails fold down for boarding access and lock upright during transport. - **Medical-grade casters with brake control** — smooth-rolling casters with reliable single-pedal brake engagement. - **Ergonomic design** — structured for patient safety and caregiver comfort during routine hospital transport workflows. ## Technical Specifications | Parameter | Value | |---|---| | Model | KL-PT004 | | Product type | Patient transportation trolley | | External size (L × W × H) | 1930 × 660 × (510–850) mm | | Backrest adjustment | 0–70° | | Height adjustment | 510–850 mm | | Height adjustment mechanism | Manual crank | | Side rails | Foldable | | Casters | Medical-grade with brake control | *Specifications are subject to change; dimensional tolerances may apply.

The wider platform and 340 mm height range make it particularly practical for facilities where the trolley serves multiple department types with different working heights, and where a maintenance-simple crank mechanism is preferred over hydraulic alternatives. ## Frequently Asked Questions ### What is the Keling KL-PT004 patient transportation trolley used for? The KL-PT004 is a general-purpose hospital patient transportation trolley used to move patients between wards, departments and clinical procedure areas. The 1930 × 660 mm platform, 0–70° backrest and 510–850 mm height adjustment support a broad range of patient types and clinical transfer scenarios. ### How does the height adjustment work on the KL-PT004? Height adjustment on the KL-PT004 uses a manual crank mechanism that operates from the foot end of the trolley. The crank provides controlled, proportional height change across the 510–850 mm range without hydraulic components, simplifying maintenance. ### What is the width advantage of the KL-PT004 compared with other models? The KL-PT004 has a 660 mm wide platform, wider than the 600 mm width on models such as the KL-PT001 and KL-PT003. The additional 60 mm reduces edge proximity for patients during transport and increases the effective support area for larger patients. ### Can the KL-PT004 be ordered in bulk or with customized specifications? Yes. Keling Medical accepts bulk orders from hospitals and medical distributors with customizable mattress and color options through its Shanghai export center.
