Skid-steer loader
The skid loader is a construction machine and belongs to the group of the wheel loader. This device is suitable for use on small sites in the gardening and landscaping or as Hoflader in agriculture, while it is characterized by its small size and light weight as well as its high maneuverability. The unit can be equipped with either a Wheel Undercarriage or with caterpillar tracks.
By using Steering Design ( skid steer ), the lateral pairs of wheels or caterpillar tracks can in the opposite direction drive (so-called Skid Steer ) what the skid steer loader enables you to turn on the spot.
The industry has developed a variety of attachments that make the machine a universal multi-purpose device. So also, for example, sweepers, augers, snow blades or grave milling can be grown alongside the usual bucket for bulk material.
Components
The skid steer loader consists of four main components:
Parameters
The power output moves in compact loaders depending on the model between 10 and 40 kW. The operating weight (net weight) is from 0.7 to 3.5 tons, the payload ( hoist load ) of 200 kg to 1500 kg and the front bucket holds up to 1.4 cubic meters. The most important feature is the compact width. Thus, the dimensions move in the range of 0.9 to 1.75 m.
Technology and equipment
The skid steer loader equipped with hydrostatic all-wheel drive. Due to the high power output of the diesel engine and the low operating weight, the machine achieves a maximum speed of up to 20 km / h The axles are designed to be rigid, the steering is accomplished via a different direction and speed of the wheel pairs on both sides. This known of tracked vehicles drive steering allows turning on the spot. The base should be secured for this purpose, since it is otherwise troubled.
As an alternative to the loaders wheew also be made with a crawler chassis. These devices will receive due to the triangular chain route the name Terrain Loaders. Delta loaders are especially designed for use on soft and slippery surfaces, since the machine's weight is distributed over a larger area and thus also improves traction.
In addition, there are special chains (eg soft greens ) exercise for highly sensitive underground even less pressure. These do not have a profile and are smooth throughout.
Further developments of the skid steer loader are now also in the charging system can be seen that normally carries out a radial movement, and recently available on the market as "Vertical lift ". This system has a higher load than is possible with Radialhubgeräten.
The control of the equipment is either mechanically, hydraulically or electro- proportional available.
To enable versatile use of the devices, many devices with an additional hydraulic connection for attachments (more than 200 different ones) are equipped, can be operated with the Hydraulic devices with up to 40 kW.
Use
Due to the small size and high maneuverability to skid steer loaders are suitable for use on smaller sites or in the garden and landscaping. A large number of attachments makes the machines used universally. The use is possible within buildings, as many skid steer loader fit through because of low width and height through doorways. Because of the many different Attachments Skid Steer Loader can be used in road construction, mining or in winter service.
Attachment tools
In addition to several different blades, special devices are available which have been specially developed for use on defined sites. There are over 200 different implements / tools.
Road construction:
- Planers
- Teerungsmaschine
- 2D/3D blade
- Compactors
- Graben-/Kabelfräse
Agriculture:
- Greiferschaufel
- Heuballengabel
Winter service:
- Snowblower
- Snow blade
General use:
- Dustpan
- Broom
- Hydraulic hammer
- Mixer
- Pallet fork
- And much more.
Many devices work just for use in road already with laser -leveling or using GPS for the preparation of flat surfaces.
Security
The statutory accident prevention regulations ( UVV short ) provide the equipment with ROPS protection device ( Rollover Protective Structure ) and FOPS with a protective device ( Falling Object Protective Structure) for earth-moving machines with an output of 15 kW.
Due to the construction, the spaces on the side or behind the skid steer loader for the device driver very difficult to see. When reversing this particular caution is required, where appropriate, a marshaller is not used.
Manufacturer
In the device class skid steer loaders, it was initially a niche product that has been manufactured by only a few manufacturers. In this context, the company Bobcat could make a name. Since the 1990s, increasingly more companies began their machine program to expand this class of equipment. These include Gehl, Komatsu, Hyundai and JCB, Caterpillar and Wacker Neuson.
