The crane-truck is a special chassis that is mounted on the car by the truck crane. It can be divided into: Dongfeng truck crane chassis, Liberation truck crane chassis, Auman truck crane chassis, Heavy-duty truck crane chassis. Chassis with the car has its own characteristics: First: The chassis is based on the characteristics of the crane, specifically for the truck crane and R & D and production. Two: In addition to carrying goods, the truck crane chassis also needs to carry the truck crane itself with a weight of 1000-5000 kg. Therefore, the chassis of the truck is overloaded. Three: The truck crane chassis is mounted on the car above the vehicle crane. So you must consider the installation space of the chassis. Especially small three-axle cars. Consider the width of the front track. Four: The chassis of the truck crane must be reinforced. General use of 280mm to 300mm beam. Before and after the bridge to increase. Before and after the spring steel plate must be thickened.
1.MT-ER Collet Chucks for Lathe CNC, also known as spring collet, is mounted on a drill \ milling machine, its function is to clamp drill cutter or knife. Er flexible collet is currently the most used. Its stable performance, high accuracy by the majority of manufacturers trust. All products are precision grinding, in line with the German DIN 6499 specifications precision manufacturing.High precision collet chuck combines advantages of DIN6499/ISO15488A standard and B standard. High speed cutting such spring collet is mainly applied to the need for good in the radial run out error.
2.proove cleanness,precsion more stable ,surface more smooth,feel more comfortable and appearance nicer. Chuck surface is coated ,the layer is evenly ,Chemical plating solution dispersion degree of almost 100%,nickel layer is thin .This special coating can reduce Spindle abnormal wear and tear.Don't influence precision .
3.We are specializing in the production of this, we can to figure to sample processing, and perfect after-sales service and technical support. Looking forward to your cooperation!
