Case 521 D 10.27t 2003-2005 - Technical data

Case 521 D - Product Description

Powertrain and Design

The Case 521 D is an advanced wheel loader weighing 10.27 t, designed for heavy construction tasks. Equipped with a Case 445 TA-M 2 engine, it delivers a power output of 82 kW at 2000 rpm. The high-quality construction ensures durability and efficiency during operation. Its compact transport dimensions are 6.79 m in length, 2.47 m in width, and 3.17 m in height. This model is also characterized by optimal balance for the tasks at hand.

Undercarriage and Hydraulics

The hydraulic system in the Case 521 D provides high performance thanks to modern technological solutions. The maximum hydraulic pump output is 135 l/min at a pressure of 250 bar. With self-locking differentials on both the front and rear axles, the machine achieves maximum traction, which is crucial when working on wet or muddy surfaces. The ergonomic cabin ensures operator comfort and excellent visibility, enhancing operational efficiency.

Operating Parameters

The Case 521 D features a bucket capacity of 1.5 m³, while the maximum lift height reaches 2.71 m. The machine's operational weight is 10,278 kg, allowing stable operation under challenging conditions. The external turning radius is 5.43 m, facilitating maneuverability in tight spaces. This model achieves a maximum speed of 38.8 km/h, accelerating the transport of materials on construction sites.

Optional Equipment

The Case 521 D offers various options for additional equipment, including different buckets and work attachments. The capability for hydraulic quick couplers as well as various types of buckets, such as tooth buckets, increases the machine's versatility. Therefore, users can adapt the device for various construction tasks. However, standard equipment does not include air conditioning or hydraulic quick couplers.

Safety and Technical Data

The 521 D model meets ROPS and FOPS safety standards, providing a high level of operator protection. The materials used and cabin construction contribute to reduced noise and vibrations during operation. Key technical parameters, such as engine power (82 kW) and weight (10.27 t), attest to the machine’s robust working capabilities. The additional set of safety features, such as electric parking brake, enhances safety in challenging working conditions.
