We can source a range of hoist and crane drives from a variety of manufacturers. Also, our engineers offer a comprehensive crane drive repair service with personalised test rigs.
We offer bespoke advice and can design an application with drive experts to support our industrial clients. Our software and hardware solutions are personalised to allow perfect integration and optimisation of the entire system.
Our AC drives provide easy speed control and total efficiency for all kinds of cranes from small hoists to large mobile cranes that can lift thousands of tons.
Our engineers have decades of experience with crane drives. Our expert teams can help you with maintenance, spare parts, technical support, and upgrades. Our service means you can prolong the life of your drive while ensuring maximum performance and trouble-free operation.
A crane hoist is a mechanical device used to lift, lower, and move heavy loads via a drum, rope, or chain system.
This is the part of a high crane made up of girders, trucks, end ties, a walkway, and the drive equipment that moves the trolley and takes it alongside the runway.
This is the unit carrying the hoisting component that moves on the bridge rails. The trolley runs on a single motor or two motors along with a shared shank.
These terms describe the horizontal beam holding up a moving hoist attached to the wall or to a column mounted on the floor.
The term describes the pointed swinging of a crane boom or crane jib in a horizontal direction. This movement is seen in cranes of a tower type.
Cranes are used across many heavy industries to move equipment or goods either in manufacturing or transportation environments. There is currently a trend to increase safety at work and to optimize efficiency in industrial operations. Cranes can make a vital contribution to these areas.
There are various types of cranes: overhead traveling cranes and gantry cranes. With these kinds of cranes a load is hung from a gripper by cables and the load behaves like a swinging pendulum. The swaying load can be a dangerous hazard. The load can also place extreme stress on the crane itself.
The way to improve crane safety is to adjust the movement of the load carefully with an AC or DC drive linked to the electric motor.
Cranes and hoists are high-performance pieces of equipment. As a result, they need four-quadrant loads. This term means they have positive speed and torque with acceleration, positive speed and negative torque with deceleration, reverse accelerating quadrant with negative speed and torque, and decelerating quadrant with negative speed and positive torque. Therefore, speed and torque can be in any direction.
DC motors are expensive to use due to high maintenance costs. As a result, they are becoming obsolete. In contrast, AC motors are robust and simple in design so they don’t need a lot of maintenance. Also, AC motors are cheap to run.
Cranes and hoists tend to use AC motors with flux vector control. However, many DC motors are still in use. When modernising an existing installation you need to consider whether to overhaul the existing DC drive or replace it with an AC motor.
