اسم المشروع: Pit‑less Through‑Floor Reciprocating Lift with C‑Shaped Access (2 Units for Factory Renovation)

العلامة التجارية المتعاونة: SEW, SIEMENS, SCHNEIDER, SICK, NSK

موقع التنفيذ: East Asia

وقت التعاون: Order Date:2026.02.08 | Shipment Date:2026.03.08

The client is a professional general contractor specializing in factory renovation and industrial finishing, undertaking an old factory reconstruction project in East Asia. The project repurposes original underground garage as the load-bearing foundation for vertical lifting equipment, requiring two identical reciprocating lifts to realize three-level cross-floor material circulation. Confined by fixed building beam structure, intact floor slab and strict 30-day delivery deadline, pit excavation is completely unavailable and non-standard C-shaped loading & unloading path is required. We completed customized structural design, compact space layout optimization and full equipment fabrication within the agreed schedule; after field installation and commissioning, both lifts are fully put into regular factory logistics operation.

التحدي والحل

تحديات العميل

The factory renovation project encountered multiple tough engineering obstacles from fixed building structure, special cargo flow design and tight production lead time.

Downward Extended Column & Pit-Free Anchoring Restriction: Vertical height from basement to ground floor reaches 4.65m with pit excavation prohibited; lift upright columns must penetrate cut floor slab and extend full 4.65m downward to anchor onto basement concrete, bringing big challenges on suspended frame stability and vertical alignment.

Ultra-Narrow Shaft Spatial Constraint: On-site structural beam spacing is only 2.65m × 2.65m square, forming extremely limited shaft envelope and restricting overall frame and component layout space.

Non-Standard C-Shaped Access Demand: Cabin dimension 1600×1600mm requires C-type feeding design along 1600mm side: goods enter from one side, shift direction inside cabin and discharge from adjacent 90° side, different from conventional straight-through or standard right-angle access.

Long Travel & Fixed Load Specification: Full lifting travel hits 16.4m with rated 500kg payload across 3 independent floor docking stops, demanding powerful drive and stable anti-deflection frame structure.

Urgent Short Production Schedule: Only 30 days available from order confirmation to finished shipment, requiring rapid customized engineering response and accelerated production arrangement for on-site variable conditions.

الحل المخصص لـ GRADIN

To overcome multiple structural and schedule limits of the East Asia renovation project, our engineering team developed customized two identical VRC-C-PLF reciprocating lifts, adopting pitless through-floor anchored frame, compact internal component arrangement, exclusive C-shaped cabin access and high-power redundant safety configuration.

1. بنية حركية ثنائية الحركة

The structural foundation adopts F120 main frame matched with J100×50×4mm connecting sectional tubes, with cabin frame fabricated from 100×50×4mm rectangular tube plus 3mm solid flat panel. All upright columns extend full 4.65m downwards through reserved slab opening and anchor firmly on basement floor; extra cross braces and diagonal reinforcing supports are added on suspended lower section to strengthen integral rigidity under 16.4m ultra-high travel height. The whole unit is directly installed on basement garage ground without any foundation pit construction, perfectly matching existing building civil condition.

2. Synchronized Drive and Load Torque Management

Each lift is equipped with 9.2kW original SEW brake motor supporting 0~40m/min variable frequency speed regulation, providing surplus power reserve for frequent start-stop and transient load fluctuation far exceeding regular 500kg specification. Adopting Grade 16A industrial lifting chain as core transmission part, constant torque output effectively offsets dynamic eccentric load impact during long-stroke ascending and descending; VFD closed-loop control realizes soft start and buffer stop to eliminate platform shaking and inertial offset in full travel range.

3. Integrated C‑Shaped Compact Access Layout

With inner cabin dimension fixed at W1600×D1600×H2700mm, the equipment adopts exclusive C-shaped access along the 1600mm cabin side. Materials load into cabin from one lateral opening, complete in-car position conversion then exit from adjacent 90° side opening. Under limited 2.65m×2.65m beam clearance, cabin, T90 car guide rails, TK5A counterweight guide rails, counterweight block and drive unit are densely and reasonably arranged inside the shaft to maximize limited available inner space and adapt narrow on-site aisle layout perfectly.

4. التكامل الكهربائي والسلامة

The whole electric system matches local East Asia industrial power standard with full IP54 sealed electrical configuration to adapt complex on-site renovation environment.

Electronic Limit Switches: Realize accurate interlock positioning and automatic stop at 3 independent floor levels to prevent over-travel running.

Dual Independent Fall Arrest Safety Gear: Two sets of separate mechanical safety gears installed symmetrically on both sides of carriage to form full redundant anti-fall protection cooperating with solid polyurethane bottom buffer.

Top Maintenance Structure: Equipped with perimeter safety guardrails and dedicated maintenance ladder on upper frame for convenient daily inspection and component servicing.

تنفيذ المشروع وإنجازاته

تفاصيل التنفيذ

التنفيذ والإنجازات

For the factory renovation general contractor in East Asia, we supplied two sets of customized pitless through-floor reciprocating lifts with exclusive C-shaped access. This compact optimized lifting solution replaces temporary manual cargo hauling and makeshift hoisting, fully resolving old plant structural transformation restrictions, narrow space bottleneck and irregular C-type material transfer difficulties.

1. تحسين العمليات المتكاملة الكل في واحد المتكامل

Original renovation site relied on trolley and manual cross-layer handling with multiple transfer links and repeated position correction. The integrated C-shaped access VRC completes one-stop loading, in-cabin steering and side unloading automatically after accurate floor docking, eliminating intermediate auxiliary handling steps and simplifying whole factory inter-floor logistics workflow.

2. تحسين كفاءة الإنتاج بشكل كبير

Tight building structure previously caused low turnover frequency and material stacking between floors. SEW high-power VFD drive realizes adjustable running speed and rapid three-level stop positioning, lifting overall cross-layer handling efficiency by over 75% and accelerating whole factory renovation progress schedule.

3. Stable Operation & Zero Cargo Damage

Manual irregular transfer easily triggers cargo collision and scratch loss; compact rigid frame structure and dual redundant safety gear keep cabin stable without shaking during full-stroke lifting. Standardized C-type fixed feeding path avoids artificial handling error, realizing near-zero damage rate for in-transit workshop materials.

4. Remarkable Civil Construction & Labor Cost Reduction

Pitless through-floor anchored design cancels expensive ground chiseling and foundation pit civil engineering, greatly cutting client’s on-site renovation construction expense. Automated vertical transportation reduces 2~3 full-time transfer operators, effectively lowering long-term daily labor expenditure.

5. Customized Adaptation for Old Factory Renovation Conditions

Tailored for narrow 2.65m×2.65m beam space, 4.65m downward suspended frame and unique C-shaped cargo flow requirement; RAL7035 anti-corrosion finish plus top maintenance ladder design fully adapt long-term dusty, variable-temperature renovation workshop continuous working demands.

الفوائد الإجمالية للمشروع

After formal installation and commissioning, the renovation project achieved over 75% logistics efficiency improvement, saved large amounts of civil modification cost and daily handling labor cost. The pitless customized reciprocating lift realizes standardized automatic cross-floor material turnover, accelerating the factory reconstruction completion progress and lifting the client’s whole renovation project economic benefit.
