As an important developing country in West Africa, Ghana has been investing more and more in the public health system in recent years, and a number of hospital construction projects are being promoted nationwide. We recently finalized a contract with a prominent local pharmaceutical company in Ghana for a complete equipment package—comprising a YHZM35 mobile batching plant and two DHBT40 concrete pumps—perfectly suited to meet the concrete production and pouring requirements for the facility’s office building and infrastructure projects.
The customer’s infrastructure project mainly includes the construction of factory office buildings and the construction of park roads. The construction scope is scattered and the operation site is not concentrated. Two core rigid requirements for the comprehensive performance of concrete equipment are put forward: on the one hand, stable and efficient mixing equipment is needed to continuously supply concrete required for construction; on the other hand, it needs to be equipped with The set of pumping equipment meets the construction needs of high-rise pouring of office buildings and long-distance road pouring.
At the same time, there are two core pain points at the customer’s site, which are also the key difficulties in this equipment selection
1. The site is scattered and the transfer demand is frequent: the project is divided into multiple construction sites, and the operation points need to be switched at different stages. The traditional fixed mixing station is cumbersome to disassemble and install, and the foundation needs to be pre-buried. The transfer cost is high and time-consuming, and it is completely impossible to adapt to the dynamic construction needs of the project.
2.Zero practical experience, low entry threshold requirements: for the customer to purchase and use the complete set of equipment of the mixing station for the first time, the team has no experience in equipment operation, debugging and installation, and urgently needs to install intelligent equipment that is simple, convenient to operate and does not require complex debugging, so as to reduce the cost of manual learning and the construction error rate.
According to the customer’s project scenario, construction pain points and practical shortcomings, our technical team combined with the overseas construction environment to tailor a complete set of YHZM35 mobile batching plant + 3 warehouse batching machine + 2 DHBT40 concrete pumps integrated solutions, taking into account the flexibility of the transfer, simplicity of operation and high efficiency of construction. It matches the needs of the project in an all-round way.
The YHZM35 mobile mixing station matched this time is designed with a low unloading height, which can directly connect to the DHBT40 concrete pump. The mixed concrete can be directly entered into the pump without the need for secondary transshipment and unloading, which greatly reduces material loss. At the same time, it perfectly adapts to the high-rise concrete pouring of the office building and the long-distance pumping construction scene of the park road. The pouring efficiency is greatly improved, and the multi-scene pouring operation needs of the project are fully met.
In response to the core needs of customers’ multi-site frequent transfer, the YHZM35 mobile mixing station adopts a modular compact integrated design of the whole machine, integrating ingredients, mixing, weighing and conveying systems. There is no need to pour a special foundation in advance, and it can be put into production after entering the site. The whole equipment can be transshipped as a whole. There is no need to disassemble the fuselage or reassemble it during the transfer process. It completely solves the problems of cumbersome transfer process, delayed construction period and high manpower cost of traditional mixing station, perfectly adapts to the customer’s decentralized construction scenario, and greatly improves construction flexibility.
The equipment adopts the integrated design of the control cabinet and the whole machine, and the line and control system are all built-in and integrated, and the commissioning is completed at the factory. When the customer’s on-site transfer and site operation, there is no need to re-wire, wiring and debugging, which eliminates the complicated circuit debugging process and greatly reduces the transfer preparation workload. Zero-base personnel can also quickly complete the site switching and put into production, adapting to the simple construction conditions of overseas sites.
Considering that the customer team has no experience in equipment operation, the whole set of equipment is equipped with a manual + automatic dual-mode intelligent control system, which can freely switch modes according to the on-site production rhythm and construction volume. The fully automatic mode can realize the automated operation of the whole process of material mixing, mixing and material discharge without manual intervention; the manual mode is suitable for small batches and refined construction scenarios. At the same time, it is equipped with a wireless remote control device as standard, which supports long-distance remote control operation. The operation interface is simple and intuitive, and the process is simple. No professional practical experience is required. The staff can get started quickly with simple training, which completely solves the customer’s operation shortcomings.
YHZM35 portable concrete batching plant is a star integrated equipment independently developed and mass-produced by EPDAS. It is specially designed for overseas infrastructure projects with limited sites, tight construction periods, frequent transfers, and small and medium-sized projects.
Integrated design
The whole machine adopts an integral frame structure, which is pre-installed and integrated at the factory. It comes with its own walking tire chassis, and the towing vehicle can be quickly transferred.
Intelligent and accurate measurement
Equipped with a fully automatic intelligent central control system and a high-precision digital measurement sensor, sand and gravel, cement, water, added agent and other raw materials can be weighed and measured independently, and the ratio error is controlled within a very small range in the industry.
Compulsory high-efficiency stirring
Equipped with a high-performance double-axis forced mixing host, with large mixing torque and fast mixing speed, excellent mixing effect for high-standard, anti-seepage and special ratio concrete, and the discharge is uniform and no separation.
Anti-corrosion and wear-resistant fuselage
The whole machine adopts sandblasting and rust removal + multi-layer anti-corrosion spraying process, and the steel structure is anti-rust, anti-corrosion and anti-aging as a whole; the material contact area is equipped with a thickened wear-resistant lining plate to resist long-term washing and wear of sand and stone.
