Over the last three years, Sáez Cranes has invested a huge amount of time, effort, and investment in the development of a new product for the Self-Erecting sector. Now, Sáez Cranes is introducing a new model of the telescopic self-erecting crane, the HT47.

This extraordinary crane is now Saez Crane’s top-of-the-range self-erecting crane, complete with a 47-meter boom and reaching a hook height of 40.5 meters.

The HT47 has been conceived and designed to include not only all the features of the equivalent competition but a host of innovations, which arguably make it a unique machine on the market.

The new HT47 self-erecting crane features a telescopic tower, combined with a hydraulic boom, which allows exceptional maneuverability. It helps in avoiding collision with obstacles such as nearby trees or buildings, and also with the serious problem of trespassing on neighbors’ property when set in free slewing mode.

The HT47 lifts 1,320 kg at a radius of 47 meters, and 6,000 kg behind. In terms of height, it is able to reach a maximum of 40.5 meters without reducing load curves. To make the operators’ work easier, faster, and safer, this new self-erecting telescopic crane is supplied with a 2 falls hook, avoiding the complexity of 4 falls technology.

This new model has two turning-radius options and has the capacity to work in both single-phase and three-phase, which is a unique functional and competitive advantage for our clients.

In the development process of the HT47, Sáez has taken into account that in some of the populous-areas where these cranes are going to work, the use of electric generators is not allowed (due to various regulations on noise pollution or environmental pollution). For this reason, making the crane work in a single-phase was always the goal from day one of the project.

The HT47 incorporates zoning as standard, and a remote control complete with display. There is a charger inside the electrical cabinet to make it easy for the operator to charge the crane’s batteries. The machine is also available in “version 4.0” for customers requiring remote access.

The new crane incorporates the most reliable technology on the market, which is why the engineers at Sáez Cranes have opted for Yaskawa inverters (drives), in addition to a second option with KEB inverters. In the same vein, the HT47 has the latest-generation motors, with an IP55 insulation protection rating, and a reduction ratio of 1:4, which makes the crane a truly high-performance piece of equipment.

The work done on the new hydraulic telescopic self-erecting crane from Sáez has also boosted the rest of the hydraulic self-erecting range:
– Introduction of single-phase technology as standard throughout the range.
– Incorporation of remote control with display as standard.
– Built-in prohibited zone system.
– Newly designed fiberglass electrical cabinet (CE/UL approved).
– Increased crane hook heights by an average of 2 metres.
– Increased peak and maximum capacities.
– Installation of 2 fall technology throughout the range.
– Option of working in ECO mode (reduces consumption by 30-40%).
– Various slow positioning speeds.
– Encoder-equipped hoisting, slewing and self-erecting motors.
