Magnet Spreader Beam for EOT Crane

A magnet spreader beam is a lifting spreader beam with electromagnetic lifters. It is a commonly seen lifting spreader in steel industry and manufacturing industry. This product is applied to lift and handle steel plates, sheets, billets, bars, coils, pipes, scraps, and other steel products. It usually works with overhead crane, gantry crane, or other hoists as a lifting device.

magnet spreader beam

Features:
1. Strong magnetic force with Max. force 18kg/cm, which ensure the workpiece will not move and be scratched during hoisting. Since the processing does not require power supply, the workpiece will not fall due to sudden power failure and loss of magnetism.
2. Rotary types are available, Optional types: upper rotary with hoist frame, and lower rotary with spreader beam.
3. Optional magnet: Electromagnet and Permanent magnet.




4. The electric permanent magnetic chuck does not need electric energy during the working process, and only relies on the permanent magnet suction to hold the workpiece, which avoids the danger of the electromagnetic system losing the magnetic force and the workpiece falling off due to sudden power failure and disconnection damage. Since the electro-permanent magnetic lifter only uses electric energy within 1-2 seconds of the magnetization and demagnetization process, it does not use any energy during work to generate safe, strong and efficient power, which is economical and environmentally friendly.



5. Electric permanent magnet jacks are widely used in the installation and handling of steel, mechanical parts and various molds due to their unique power-saving, energy-saving and safety performance. They are used in the lifting and handling of machinery processing, shipbuilding, engineering machinery, automobiles and other industries. The preferred lifting tool for operations, we often see this kind of products in factories, docks, warehouses, and transportation industries.



6. This magnetic lifting beam can be used with magnetic overhead crane or gantry crane to thick plates with thickness ≥5mm. Users can use multiple electro-permanent magnets for joint hoisting, with multi-stage magnetic adjustment function, and precise control of the magnetic penetration depth of the spreader, which can ensure that the next steel plate is completely non-sticky, which greatly improves the lifting efficiency of the steel plate. Different lifting tonnages Magnets can be grouped and controlled to adapt to steel plate spreaders of different lengths, which greatly improves the efficiency of steel plate lifting.



7. The magnetic block can be round disc type, square type, rectangle type, etc.

Carbon Brush Current Collector for Bridge Crane and Gantry Crane

Carbon brush current collectors for Overhead Crane can be single pole busbar collector, multi-pole busbar collector, seamless conductor rail collector, copperhead conductor rail collector, etc. Its performance, quality, material and the structural components of the material will directly affect the safe operation quality of the whole system equipment. Therefore, the current collector is one of the most important component of the entire conductor rail system. For your different requirements on current, busbar type or installation, we always offer you the right current collector and solutions.

Carbon brush current collectors

The carbon brush current collector is composed of carbon brush, stainless metal part and wear resistant plastic part. Spring can make the carbon brush maintain uniform contact. There is a traction arm for each group collector. The double collector system can be used for guiding device or higher current device.



The jointless conductor rail current collector is one of the main devices for picking up electric energy from the collecting side of the conductor system, and the electric energy is directly transmitted to the electric appliance through the sliding contact between the collecting brush and the guide rail, thereby realizing mobile power supply of cranes.



The current collector consists of a mechanical structure tension device and a collector brush that directly contacts the guide rail. The tension device of the mechanical structure determines the sliding contact pressure of the collector brush and the guide rail and the stability of the mechanism. The brush is the conductor of the sliding contact of the guide rail to pick up the electric energy.

Travel Switch for Crane Hoist

Travel switch is a travel limit and terminal protection for the crane traveling or hoisting. The travel switch can be a trolley travel switch. When the trolley approaches the limit position, the operation is stopped in one direction and can be operated in the reverse direction. The function of a crane travel switch is similar to the trolley travel switch.

Travel switch

1. Application scope: Interlock protection.
2. This travel switch is a usual master switch.
3. Its functional principle is like buttons: Switching circuits based on the routing position of traveling parts.
4. The travel switch could be widely used in many areas, like various machines and cranes.
