First Cranes’ Control Panel and Electric Components Connection
Introducing First Cranes' Control panel and electric components connection. As a crane manufacturer and supplier, First Cranes will provide you with all types of crane parts. The crane control panel and related electric components are of high quality. Crane control panels help you control your overhead crane and gantry crane. There are many different types of crane control panels at your selection such as crane cabinets. The crane control panel system keeps your crane under control. At First Cranes, we provide our customers with the crane control panel/cabinet, electric switchgear and a complete set of electric control panels. We also help you with site installations and commissioning services. We can also redesign or remanufacture nonstandard electric crane control panel received from our customers.
Advantages of the crane control panel system:
The crane control panel system is custom-designed to meet various needs.
Compact breaker design of crane control panel system is safe and easy to use.
The innovative drawer design complies with ergonomic requirements.
Compact breaker design offers safe and convenient operation.
Pull-out drawer design complies with the ergonomics requirements.

Mains can enter the enclosure either from the top or behind.
Limit Switch
First Cranes offers different types of limit switches that control crane safety and crane movement. The limit switch is a critical component of overhead crane safety. Limit switches are electromechanical devices that regulate everything from household appliances to industrial machinery. For an overhead crane, they provide solid, established points of reference for maintaining efficiency, reliability and safety standards.
Limit switches have practically limitless applications in regulating crane operation to prevent potential incidents. For instance when ropes come out of the groove or in preventing two trolleys from impacting on the same bridge structure. It also keeps a crane from lifting loads above-rated capacity. There are types of limit switches that prevent a hoist from reaching the upper block and rope drum, other types help in protecting motors from overheating. Limit switches help ensure safety and keep the potential harm in a low-to-average level. Each limit switch should be inspected and maintained regularly. Limit switches wear out over time, as they open or close electrical circuits.
They should be checked daily before a crane is used to monitor faults and replace switches before they fail. Knowing how a limit switch works is important for understanding how the crane works and how these established set points keep the crane operating safely and efficiently. In some cases, there may be multiple limit switches associated with a crane operation such as crane travel or hoist motion. The first switch will signal that the end of the safe travel limit is approaching and slows the crane motion. A subsequent switch will indicate that the end of the safe travel distance has been reached, and stops the motion. Hoisting motions may be served by several limit switches, which provide setpoints for safety and reliability. An initial limit switch will slow the hoist before it reaches the stop limitation. Slowing the hoist before reaching the limit decreases mechanical wear, as the hoist is travelling below maximum speed when the brakes set. The “up” stop-limit switch provides a safe position for the hoist to stop motion for safe travel motions and standby positions.
An additional limit beyond the stop limit—typically called the “ultimate limit”—prevents the hoist block from impacting the drum. The ultimate limit acts as a safeguard in the event the stop limit fails or is set improperly. This extra limit prevents two-blocking—that is, when the hook block contacts the drum hoisting machinery. Two-blocking is one of the most dangerous incidents involving cranes, as it can snap wire ropes and cause dropped loads and other catastrophic accidents. After being tripped, the ultimate limit may require a manual reset. This involves resetting a wedge component or lever so that an inspection can be carried out to determine why the crane reached this position and did not stop at the up stop-limit position. Limit switches can also be used for travel motions, providing consistent and predictable motion limitations without impact at end stops.
In automated environments, lasers or encoders track positions of crane movements. Limit switches provide consistent calibration points to ensure values being used are accurate for safety and reliable production. First Cranes uses limit switches to calibrate Sway Control height and other critical measures of repeated accuracy to control real-world position.
First Crane controls have your crane under control efficiently and safety. First Cranes emerged in the industry as a manufacturer and supplier, we are engaged in offering Crane Controls such as pendant controls and pendant push-buttons. We supply and install various types of crane Control Systems to all kinds of electric hoists and Overhead Cranes. We supply a wide range of excellent quality remote crane controls and receiver kits that are easily integrated into the existing crane controls.
Crane controls enable full operation of all motions and speeds including emergency stop features. First Cranes control systems comprise a handheld radio remote crane control (two with some brands), a charger and a receiver. The radio remote transmits the signal and command that you have selected which is instantly received and transferred into the controls of the crane or hoist by the receiver to carry out the task instantly.
Features of Crane controls
First Cranes' radio remote crane control system is wireless, ergonomic, and aesthetically designed. It enables the crane operator to remotely operate the crane or hoist, allowing him to gain a safe distance from the load therefore, take a better point of view when operating. Our offered products are designed and developed using optimum-grade raw materials and allied components that are obtained from the trusted vendors of the industry. We store these products at our spacious warehouse.
