Service brake YWZ-200/25 YWZ-300/45

The lifting and lowering speed of heavy objects during driving should be stable and uniform, and sudden braking is not allowed; The left and right rotation should be balanced, and no reverse action should be taken before the rotation has stopped steadily; When lifting at or near full load, it is strictly prohibited to lower the arm or perform two actions simultaneously. When lifting objects, the rope should be pulled and the speed should be uniform. Sudden braking and changing direction are prohibited; When operating the controller, do not directly change the direction of operation. When the crane needs to travel with a load, the load should not exceed 70% of the allowable lifting capacity, the walking road should be solid and flat, the weight should be in the front direction of the crane, the weight should not be more than 500mm from the ground, and the pulling rope should be tied and the crane should travel slowly; Long distance driving with load is strictly prohibited. The ground of the crane is uneven, and it is prohibited to perform two actions simultaneously when lifting the service brake. When using two or more cranes to lift the same heavy object, the steel wire rope should be kept vertical; The lifting and operation of each crane should be synchronized; The load borne by each crane shall not exceed the rated lifting capacity of each location. There are various models of electric hydraulic thrusters, but their working principles are similar. After being powered on, the motor inside the hydraulic brake drives the centrifugal oil pump inside the hydraulic brake head, increasing the hydraulic oil pressure. Hydraulic oil transfers pressure to the piston in the oil cylinder, and the hydraulic push rod moves upwards driven by the piston to open the brake shoe. JELITA, electric hydraulic thrusters are used for driving devices of various block brakes and disc brakes. Do you know the working principle of electric hydraulic thrusters? Let the editor of Jintou explain it to you. There are various models of electric hydraulic thrusters, but the working principle is similar, and the structure is shown in the following figure. Working principle of electric hydraulic thruster Working principle of electric hydraulic thruster: technical data of hydraulic holding brake (taking the technical data of MYTI-90 electric hydraulic thruster as an example): thrust 900N, stroke 80mm, rising time 0.8S, Fall time 0.5S, power 0.25kW. Equipped with No. 20 engine oil, with a weight of 720 operations per hour. The matching brake model is (the combination of the thruster and brake can form a hydraulic brake). YWZB Standard Drawing

Working principle of crane brake:

Although the crane brakes are different according to different types of operation requirements, they play the same function in Gantry crane, mainly by controlling the rotation and inertia movement of the motor, so that the control equipment can be stopped, accelerated or decelerated in a certain motion state. Due to the operational function of the crane, brake failure is absolutely not allowed during the lifting of heavy objects. If the brake failure causes inertia control to fail, it can damage the equipment or threaten the health and safety of surrounding personnel. Therefore, the brake plays a very important role in the safe and stable operation of the crane equipment.

The crane brake mainly includes lifting mechanism, running mechanism, luffing mechanism, slewing mechanism, and metal structure. The lifting mechanism is the basic working mechanism of a crane, mostly composed of a suspension system and a winch, and there are also hydraulic systems for lifting and lowering heavy objects. The operating mechanism is used to vertically and horizontally transport heavy objects or adjust the working position of the crane, generally consisting of an electric motor, reducer, brake, and wheels. The luffing mechanism is only equipped on boom type cranes. When the boom is raised, the amplitude decreases, and when it is lowered, the amplitude increases. There are two types of luffing: balanced and unbalanced. The slewing mechanism is used to rotate the arm frame, which is composed of a driving device and a slewing support device. The metal structure is the skeleton of a crane, and the main load-bearing components such as the bridge, boom, and gantry can be box or truss structures, or web structures. Some can use steel sections as support beams

Some working characteristics of lifting equipment are intermittent movements, that is, the corresponding mechanisms for picking up, transporting, unloading, and other actions in a working cycle work alternately. The development and use of cranes in the market are becoming increasingly widespread. Due to the lack of support legs for lifting and frequent accidents during lifting, the traveling speed is also faster than that of crawler cranes (crawler cranes); Stable operation, large lifting capacity, capable of lifting and walking within a specific range, but must ensure that the road is flat and solid, the tire pressure meets the requirements, and the lifting distance from the ground must not exceed 50CM; Prohibit long-distance walking with load

The company mainly produces all kinds of brakes and electric hoists for single and double beam bridge cranes and Gantry crane. Suitable for workplaces such as mines, freight yards, docks, etc. The product is best-selling in more than 20 provinces and cities across the country. Having the production capacity and rich experience in contracting the manufacturing, installation, and maintenance of special, large, and special lifting machinery equipment, able to meet the product standards and requirements of various customers.
