tracked vehicle

Abstract

Tracked vehicle (1) comprising a carrier vehicle (2) with two interconnected track drives (3) and a superstructure (4) mounted on the carrier vehicle, wherein the superstructure has a base frame (5) with a loading platform (6) and two telescopic extension boom arms (7) are arranged laterally on the base frame, by means of which a load can be loaded onto the loading platform.

Description

The present invention relates to a tracked vehicle. Various tracked vehicles for off-road use are known in the prior art. These known tracked vehicles can transport loads or operate attachments. However, they are limited in terms of load capacity and the attachments that can be used simultaneously. The present invention therefore aims to provide a tracked vehicle that overcomes the aforementioned disadvantages. The problem is solved by a tracked vehicle according to claim 1. Preferred embodiments are each the subject of a dependent claim. According to the invention, a tracked vehicle is provided which comprises a carrier vehicle with two interconnected track systems and a superstructure mounted on the carrier vehicle, wherein the superstructure has a base frame with a loading platform and two telescopic extension boom arms are arranged laterally on the base frame, by means of which a load can be loaded onto the loading platform. The base frame is made, for example, from I-beams, preferably with dimensions of approximately 10 cm × 10 cm. The superstructure is mounted onto the carrier vehicle via an adapter plate welded to the underside of the base frame. The carrier vehicle has, for example, a payload capacity of approximately 2.3 t. The loading area corresponds, for example, to the size of a Euro pallet. Using the outrigger arms, loads of up to approximately 1.8 tons can be loaded onto the loading platform. The advantage is that even heavy loads can be picked up, loaded, and transported in rough terrain without the need for an external lifting device. In a preferred embodiment, pivoting support arms are arranged at the corners of the base frame. This increases the stability of the tracked vehicle and prevents tipping even under heavy loads. Advantageously, wheels are provided at the ends of the support arms. These wheels allow the tracked vehicle to be operated safely even on slopes. Furthermore, it is advantageous if the boom arms can each be raised and lowered by means of a hydraulic cylinder. This allows the boom arms to be adjusted with minimal operator effort and high lifting force. In a further advantageous design, the boom arms are secured with bolts at the rear of the tracked vehicle. This reliably fixes the boom arms in their respective installed positions. In another preferred embodiment, the boom arms include a cross brace with attachment points. Loads can be distributed symmetrically between the two boom arms via the cross brace. Preferably, a lifting device, in particular a chain, a rope or a sling, is provided at the attachment points. This allows the lifting device to be adapted to the load to be lifted. In a further advantageous embodiment, anchor points for securing a load are arranged at one edge of the loading platform. For example, four anchor points are provided to which the load can be secured using tension straps or ropes. Furthermore, foldable extensions, operated by hydraulic cylinders, can be provided at the edge of the loading platform, for example at its front, rear, and side edges, to prevent the load from slipping. In a further advantageous embodiment, the base frame features mounting points for attachments, with these points located at the front, rear, both sides, and / or on the loading platform. This allows the tracked vehicle to be equipped with a wide variety of attachments, enabling the simultaneous operation of multiple attachments. Examples include a winch, a three-point hitch, or a double-knife cutter bar. Bayonet couplings can also be provided on the boom arms, allowing, for example, the attachment of robotic arms. The attachments can be controlled, for instance, via cable, remote control, or autonomously. It is also advantageous if the tracked vehicle has an electric motor-hydraulic pump unit as its drive system, for example, with a power output of approximately 30 kW. Such a drive unit is low-emission and low-noise. Power is supplied, for example, by sodium-ion batteries distributed within the base frame, which can be combined with supercapacitors to cover peak loads. A hydraulic control unit can be switched by means of an electrical control unit. Furthermore, electrical sockets for operating electrical devices can be provided on the tracked vehicle. Finally, it is advantageous if the tracked vehicle has an onboard computer for autonomous control. This allows work processes to be carried out automatically without constant operator intervention. Training data for the autonomous control system can be uploaded, for example, via USB stick or SD card. Alternatively or additionally, the tracked vehicle can be operated via a wired or wireless remote control. Further advantages of the invention are described in the following exemplary embodiment. Figure 1 shows a schematic side view of a tracked vehicle according to the invention. As shown in Fig. 1, the tracked vehicle 1 comprises a carrier vehicle 2 with two interconnected track units 3, one of which is visible in Fig. 1. A superstructure 4 is mounted on the carrier vehicle 2. The superstructure 4 has a base frame 5 with a loading platform 6. Two telescopic extension arms 7 are arranged laterally on the base frame 5, one of which is visible in Fig. 1. A load can be loaded onto the loading platform 6 by means of the extension arms 7. The extension arms 7 can each be raised and lowered by means of a hydraulic cylinder 8, one of which is visible in Fig. 1. A lifting device 9 is provided on the extension arms 7, which is shown by way of example as a hook in Fig. 1.
