ULMA manufactures formwork and shoring systems for construction projects worldwide.

Its high-capacity shoring solutions include MK Heavy Duty Shoring Towers and the ALUPROP Aluminum Prop. Designed for a range of jobsite conditions, these systems are used on bridges, large civil structures, and building projects. This article examines their key specifications and applications, along with examples from completed projects.

Key ULMA Shoring Solutions

Applications for MK Heavy Duty Shoring Towers

MK Heavy Duty Shoring Towers are high-capacity falsework systems designed to support heavy structures on civil engineering projects. Their modular design uses components ranging from 0.75 to 3 meters, allowing crews to configure the system around specific jobsite requirements.

The MK-360 is designed for bridges and other large structures. The MK-150 provides low-height shoring for beams and slabs, while the MK Prop can be used as supplemental support in confined areas. A limited set of components can be combined in multiple configurations, helping streamline assembly and dismantling.

Optional guardrails and stairways can be added to support safer work at height.

Weight Available upon request
Load Capacity MK-360: Approximately 250–360 kN per prop
MK-150: Approximately 100–150 kN per prop
MK Prop: Varies by configuration
Material Steel (MK Beam)
Module Length 0.75–3 meters

ALUPROP Aluminum Prop

Applications for the ALUPROP Aluminum Prop

ALUPROP is a high-capacity aluminum prop system that complies with European standard EN 16031. Its lightweight, high-strength construction makes it suitable for applications such as slab formwork and beam support.

Freestanding towers can be assembled to heights of up to 6 meters and extended or interconnected to reach up to 12 meters. The system also features self-cleaning threads and an integrated anti-drop mechanism.

Crews can assemble the system at ground level and lift it into position by crane, reducing the amount of work performed at height and improving installation efficiency. It is well suited to projects that require shoring to be installed quickly, including building and bridge construction.

Weight 29.6 kg (ALUPROP 4.5–6.0 model)
Load Capacity 39.1 kN (in accordance with ANSI/ASSE A10.9)
Material Aluminum
Overall Length Up to 6 meters with a single prop
Up to 7 meters with a 1-meter extension

ULMA Shoring Project Examples

Comuneros II Bridge

ULMA’s MK Heavy Duty Shoring Towers were used in the construction of the Comuneros II Bridge, a 724-meter cable-stayed bridge in Peru’s Junín Region.

During construction of the bridge deck, six 15-meter-high MK towers were installed at 62-meter intervals in each span. The towers provided stable temporary support for the project’s heavy loads during construction of the composite steel-and-concrete deck.

National Police Hospital

ULMA supplied multiple formwork and shoring systems for the National Police Hospital project in Lima, Peru.

The development includes a six-story hospital and a four-level parking structure. To accommodate the project’s complex slab and beam construction, crews used a combination of ENKOFLEX beam formwork, ALUPROP towers, and BRIO shoring. The energy-efficient, seismic-resistant project required the coordinated deployment of more than 1,000 tons of equipment. Reusing the formwork systems also helped reduce the project’s environmental impact.

For Contractors and Commercial Projects

Project-Specific Engineering and Technical Support

ULMA provides engineering support to contractors using its formwork, shoring, and scaffolding systems. Its engineers develop project-specific configurations using standardized products and can prepare 2D plans, 3D models, technical studies, material lists, and recommendations for complex geometries. BIM-based planning services can also help teams analyze construction sequences, calculate component requirements, and coordinate delivery and return schedules. Plans may be reviewed and revised as jobsite conditions or project requirements change.

Sales, Rental, and Project Logistics

ULMA offers both purchase and rental options for commercial projects. Customers purchasing ULMA systems may receive engineering support, assembly training, maintenance assistance, and access to technical personnel for large-scale work. The rental service gives contractors access to a broad range of equipment without requiring an investment in permanent inventory. It may also include project-specific engineering and material planning based on the construction schedule. ULMA’s logistics teams plan phased deliveries, coordinate urgent shipments, transfer equipment between logistics centers, and manage large orders. Availability and service details vary by country and should be confirmed with the nearest ULMA representative.

On-Site Assistance and Workforce Training

ULMA can provide ongoing on-site assistance to help contractors use its systems correctly and efficiently. Field engineers, site supervisors, and sales support personnel coordinate day-to-day requirements, respond to changes in material demand, and monitor equipment use. Training covers the safe assembly, operation, maintenance, and handling of ULMA systems. The team can also review equipment turnover and help organize returns, reducing the amount of unused material left on site.

For Local Builders and DIY Customers

No Dedicated Support Program for Individual DIY Customers

ULMA’s official website does not advertise a dedicated service for individual consumers undertaking small DIY projects. Its sales, rental, engineering, logistics, and on-site support services are described in the context of construction projects, contractors, professional jobsite teams, and industrial maintenance work. The company’s inquiry form also requests a company name and allows customers to submit project drawings or technical documents.

The available information does not confirm the availability of rentals without minimum-order requirements, single-prop DIY rental programs, residential delivery, or simplified instructions for inexperienced homeowners. Individual customers should therefore contact ULMA or a local representative to confirm whether direct sales or rentals are available before planning a purchase.
