Product Introduction

It features a powerful new National IV emission standard engine for complete fuel combustion and high efficiency; an advanced power control system fully utilizes pump and valve performance, ensuring high efficiency of actuators. The high-efficiency construction head has a fast rotation speed and high soil-throwing efficiency; the main winch has fast lifting and lowering speeds; the fully electronic control system offers fast response, sensitive operation, strong micro-motion capability, smooth composite actions, and rapid and precise control. The high-efficiency rock drilling head has high torque, and the double-ratio flexible winch prevents tilting under pressure, providing strong hard rock drilling capability and good stability. It is stable and reliable, ensuring stable rotation and parking during drilling in hard rock strata, resulting in high overall construction stability and high hole quality; the long lower carriage and wide extension contribute to a low center of gravity and more stable construction; the single-layer winding drum eliminates wear between wire ropes, extending service life and reducing operating costs; the new counterweight requires no adjustment and ensures reliable connection. The intelligent, high-definition touchscreen integrates display, control, and leisure functions, boasting a technologically advanced interface and simple operation. The intelligent drilling function allows for human-machine separation, reducing operator fatigue. The new intelligent cockpit features significantly improved air conditioning performance, with optimized airflow placement and sealing design ensuring consistently low noise and a constant temperature. A larger right-side glass area provides a wider field of vision. Convenient maintenance walkways and guardrails enhance safety during repairs; dual-side ladders ensure unobstructed access for maintenance; and a standard automatic centralized lubrication system saves time and effort.

FAQ

How to protect equipment during transportation to avoid collision, rust, or component damage?

Multi-layer protective measures need to be adopted, covering the entire process of packaging, fixing, and monitoring:

Packaging Protection: Wrap collision-prone components (e.g., cab glass, hydraulic pipeline interfaces) with bubble film and plywood boxes; spray anti-rust oil on exposed metal parts (e.g., boom connection pins, track plates) and cover them with waterproof tarpaulins; install waterproof and dustproof covers for electrical components (e.g., display screens, sensors).

Transportation Fixing: Lay anti-slip rubber pads on transportation vehicles (flatbed trucks, railway flatcars), fix the equipment in special card slots with high-strength steel wire ropes or chains, and place rubber blocks at the contact points between the steel wire ropes and the equipment (to avoid wear on the paint and metal surfaces); for crawler-type equipment, additional fixing of the track tensioning device is required to prevent track loosening during transportation.

Full-Process Monitoring: Install GPS positioning systems and temperature-humidity sensors on transportation vehicles to monitor the transportation route and the environment inside the carriage in real time (e.g., coastal transportation needs to prevent rust caused by high temperature and humidity); during long-distance transportation, arrange escorts to check the fixing status regularly and re-tighten the steel wire ropes in time if looseness is found.

After the equipment is delivered to the construction site, what key processes need to be completed for delivery acceptance?

The acceptance needs to be participated in by the manufacturer and the customer (or the construction party), with the core process including 3 steps:

Appearance and Accessory Inspection: Compare with the delivery list to check whether the equipment appearance has transportation damage (e.g., paint scratches, component deformation), and confirm whether the accompanying accessories (e.g., spare filters, tool kits, operation manuals) are complete. If there is any shortage or damage, take on-site photos for records and have both parties sign for confirmation.

Performance Testing: Conduct no-load test runs (e.g., start the engine to check the running sound, operate the working device to test the movement flexibility) and load tests (e.g., excavate loose soil with an excavator to test the digging force, lift standard counterweights with a crane to test the lifting stability). The test data must meet the requirements of the equipment technical parameter sheet.

Document Handover and Training: The manufacturer hands over the equipment technical documents (e.g., certificate of conformity, warranty card, maintenance manual) to the customer, and conducts on-site training for the operators at the same time. The training content includes equipment operation specifications, daily inspection items (e.g., oil level inspection, tire pressure detection), and emergency handling methods (e.g., emergency start for engine shutdown). After the training is completed, both parties sign the Equipment Acceptance Form to confirm the completion of delivery.

If the equipment is damaged during transportation due to force majeure (e.g., heavy rain, earthquake), how to divide the responsibility?

The responsibility division is mainly based on the transportation contract agreement and insurance clauses, usually following the following principles:

Transportation Insurance Purchased: If the manufacturer or the customer has purchased "cargo transportation insurance" for the equipment, and force majeure is within the insurance coverage, the insurance company will settle the claim according to the loss degree (e.g., repair costs, component replacement costs). After settling the claim, the insurance company may claim compensation from the third party causing the loss (e.g., the road management party failing to clear the collapsed road section in time).

No Transportation Insurance Purchased: If no insurance is purchased, check the "force majeure liability clause" in the transportation contract—if the contract stipulates that "the carrier only bears routine transportation risks, and the loss caused by force majeure shall be borne by the cargo owner", the loss shall be borne by the customer (cargo owner); if the contract stipulates that "the carrier shall fully ensure the safety of the cargo, and still bear part of the responsibility under force majeure", the carrier and the customer shall negotiate to share the loss (usually in a ratio of 3:7 or 4:6).

Special Agreements: If the equipment is a customized product and cannot be repaired after being damaged due to force majeure, or cannot meet the use requirements after repair, both parties may negotiate to re-produce (the cycle and cost need to be re-confirmed) or terminate the contract. The specific implementation shall be in accordance with the "customized product delivery breach clause" in the contract
