Electric Trolley

Features

• It consists of hook and pulley. The hook material is DG34CrMo. The pulley material is Q235 hot-rolling. It adopts anti-friction roller bearing, the hook can be a 360degree rotation. It is equipped with spring-pressed safety lock, preventing from slipping off. All pulleys use a maintenance-free bearing, the design can efficiently prevent abrasion between steel rope and pulley shell. It has delicate overall structure and volume as well as nice appearance.

• Use safe, reliable transmission performance coupling to connect the various agencies of transmission components, torque transmission at the same time compensate for certain installation errors caused by the angle and radially offset to improve the dynamic characteristics of the transmission.
• Brake wheel coupling includes brake wheel and braking unit.
• The transmission shaft adopts 45# steel material, which is strictly calculated by strength (static strength and fatigue strength).Ensure its strength and reliability, and smooth the transmission torque.

• Characteristics of wire rope: fiber core wire rope soft, good bending performance. The fiber core can have buffer function when the wire rope is subjected to collision and shock load during work. It has the characteristics of toughness, water absorption, acid resistance, alkali resistance, corrosion resistance, and extrusion, etc. The steel wire rope is not easy to deform in the use of dynamic load, and the diameter is uniform and stable

• It is of cam rotary type, 4 steps adjusting, up and down limitation, auto-resetting, safe and reliable. The lifting pre-limitation can reduce the impact; extreme limitation can avoid the hook from over-lifting.

• Adopt YWZ series hydraulic brake, this series brake uses pusher as the actuator of the brake. Electric hydraulic booster is a kind of integrated motor, centrifugal pump, oil cylinder, and very compact drive control device. Installation size conforms to JB/ZQ 438-1997 standard. It is mainly used for mechanical braking of mechanical driving devices such as lifting transportation, metallurgy, mining, port, and building.

• All speed reducers in our company have installed an oil receiving device to avoid the oil stain caused by an oil change. The soft tooth surface reducer is the most advanced common structure design, with the steel plate welding, the gear is high-quality low carbon alloy steel, it's widely used.

• Motor adopts YZR series crane special use winding rotor three-phase asynchronous motor. YZR series motor is suitable for driving various kinds of hoisting machinery and metallurgy auxiliary equipment, with high overload capacity and mechanical strength, especially for short-term or intermittent operation, frequent start-up, braking and significant vibration and impact of equipment. This motor has a good seal, its protection grade is IP54, insulation grade is F class.

• Trolley is installed JHQ polyurethane buffers, it has the good performance of absorbing the moving mechanism energy and reducing the impact, and its ability to withstand collision meet GB/T 3811-2008 in clause 4.4.6

• It is of IP65 protection class, air plug, and fast-easy installation; Schneider/Siemens/CHINT electrical kits, etc.
