10‑Ton Mechanical Tipping Platform｜Shandong University Rock Crushing Experiment

Q: <strong>Will the rock tip or wobble during flipping due to irregular shape and off‑centre gravity?</strong><div><span style="font-weight: 600;">

Réponse : No. The dual platforms are rigidly connected via a common shaft and 20A‑2 double chains – both sides move in perfect sync. The J200×100×8 heavy‑duty frame resists bending even with extreme eccentric loads. The motor brake locks at any angle – no hydraulic creep.

Q: <strong>Why use a mechanical chain drive instead of hydraulic cylinders?</strong><div><span style="font-weight: 600;">

Réponse : Rocks are rough and create impact shocks – hydraulics leak and wear quickly under such loads. Dual‑cylinder synchronisation is also difficult with eccentric loads. Chains are rigid, impact‑resistant, and maintenance‑free (just regular lubrication). They guarantee perfect synchronisation without the complexity of hydraulics.

Q: <strong>The platform is 1500×1500mm – how do you fit rocks larger than that?</strong><p data-start="9499" data-end="9620"></p>

Réponse : Removable 200mm wing plates are bolted to each side – expanding the deck to 1700×1700mm. The plates are FEA‑verified for 10‑ton loads. They can be unbolted easily when not needed, restoring the standard size for forklift access.

Q: <strong>4. How do you get a 10‑ton rock onto the platform with a forklift?</strong><div><span style="font-weight: 600;">

Réponse : Two removable rectangular tubes are fixed under the platform as guide slots. The forklift forks slide along the tubes to place the rock securely, then back out. The tubes are bolted to the frame and can be removed after loading, leaving a flat deck. One forklift, one operator – no crane needed.

Vue d'ensemble

Type de projet : Heavy‑duty mechanical tipping platform (dual platforms, 90° tilt)
Client : Shandong University (Geotechnical & Structural Engineering Research Centre)
Secteur : Higher education research (rock mechanics, deep rock engineering)
Fonction principale : 90° tipping of 10‑ton natural rock blocks for multi‑angle breaking, sampling, CT scanning, and compressive strength testing
Paramètres clés : 10‑ton capacity, dual independent platforms (1500×1500mm each), removable wing plates (expand to 1700×1700mm), mechanical chain drive (20A‑2), 4kW motor, wireless remote control

Contexte du client et exigences en matière de recherche

Shandong University’s Geotechnical & Structural Engineering Research Centre conducts rock mechanics studies on deep tunnels and underground caverns. For expériences de concassage de roches, researchers need to flip 10‑ton irregular natural rock blocks 90° to access multiple faces for breaking, sampling, CT scanning, and strength testing.

Traditional methods (cranes or manual levers) are unsafe, imprecise, et damage samples – risking injury, compromising test repeatability, and destroying rock structure.

Le client avait besoin d'un smooth, precise, and repeatable flipping device, with forklift loading/unloading and a platform adaptable to varying rock sizes (up to 1700mm after expansion).

Défi

Extreme eccentric load and impact: Irregular natural rock blocks have large centre‑of‑gravity offsets. The impact forces generated during tilting under 10‑ton eccentric loading far exceed regular uniform loads – demanding exceptional structural rigidity.
Forklift loading/unloading: The forklift forks must slide under the platform to place the rock. A solid platform base would block access.
Size adaptability: Rocks may exceed 1500mm – the platform must be expandable without replacing the equipment.
Operational safety: Operators must stay at a safe distance during flipping to avoid injury from sudden cracking or overturning.
Urgent delivery: Ordered on December 22, required shipment by January 10 – just 20 days.

Solutions

Dual‑platform mechanical flip structure – handling eccentric load and impact

Design approach: Conventional hydraulic tippers work well for regular workpieces, but rock blocks have large centre‑of‑gravity offsets and rough surfaces. Hydraulic systems are prone to leakage and pressure loss under eccentric impact. This equipment uses deux plates-formes indépendantes + entraînement mécanique par chaîne:

Two 1500×1500mm platforms support the rock at both ends. A 4kW motor drives 20A‑2 double‑strand chains to rotate both platforms synchronously 90° around a central shaft – flipping the entire rock smoothly.

Drive: 4kW motor + 20A‑2 double‑strand chain (high safety factor, impact‑resistant)
Frame: J200×100×8 rectangular tube – rigid enough for 10‑ton eccentric loads
Platform deck: 8mm thick steel plate – wear‑resistant

Removable wing plates – flexible size expansion

Requirement: Rock dimensions may exceed 1500mm, requiring temporary platform enlargement.

Solution: Two Plaques d'aile amovibles de 200 mm de large (screw‑fixed) are added on the long and short sides of each platform. With wing plates installed, the platform size becomes 1700×1700mm. The wing plates are removed when not needed – no interference with forklift access.

Forklift guide tubes – solving the loading/unloading problem

Challenge: Forklift forks must slide under the platform to place the rock. A solid platform base blocks access.

Solution: Two tubes rectangulaires amovibles sont ajoutés à chaque plate-forme, fixés sous le pont pour former des fentes de guidage pour les dents de la fourche. Le chariot élévateur fait glisser ses fourches le long des tubes, dépose la pierre, puis recule. Les tubes sont vissés et peuvent être retirés après les expériences, laissant une surface de plate-forme plane.

Wireless remote control – ensuring operator safety

Safety requirement: Operators must stay at a safe distance during 10‑ton rock flipping.

Solution: A télécommande sans fil allows the operator to start, stop, and reset the tilt from a distance. The motor has a self‑locking brake to hold the angle when power is off.

Livraison urgente

Challenge: Ordered December 22, required shipment by January 10 – only 20 days.

Solution: Priority production scheduling; key components (motor, chains, bearings) pre‑stocked. Shipment made on January 10 as required.
