Revisions and special assessments
We have our own team of inspection technicians for dedicated lifting equipment and dedicated electrical equipment. We carry out inspections and tests not only on the equipment supplied by us, but also on lifting equipment from other manufacturers.
We also carry out special crane assessments in the scope according to ČSN ISO 12482, which must be carried out according to ČSN 27 0142 if the actual operation of the crane is close to the designed service life, while maintaining the manufacturer's prescribed load spectrum. Special assessments are also carried out on the basis of the user's request, when it is necessary to assess in detail the actual technical condition of the crane.
Scope of work:
extraordinary electrical revision, including the supply
checking the accompanying and operating documentation and comparing it with the actual condition of the crane.
visual inspection and measurement of wear parts: wear of running, guiding, friction (braking) and other crane components (wire ropes, discs, lining, wheels, rails), with measurement of their functional surfaces and material loss (wall thickness, lining, etc.)
visual and mechanical inspection of machine mechanisms
in-depth inspection of gearboxes during their partial disassembly (condition and backlash on gears, backlash in gears, shafts),
inspection of mechanical connections (pin, bolt, rivet),
visual, mechanical and ultrasonic NDT ultrasonic inspection of the main supporting parts of the steel structure of the crane and cat
inspection and functional test of restraining, securing, controlling, sensing, signalling elements (acoustic and optical signalling), functional test of the control and management system (if the crane is equipped)

overall optimization - weight reduction, dimensional adjustment, modification of profiles and cross-sections, effective increase of stiffness
verification of stability and safety, taking into account potential risks from the surrounding environment
analysis of internal forces, reactions, transformations, stresses, deformations
calculations of natural frequencies
residual life assessment based on realistic operating conditions
For static and strength calculations we use professional programs Autodesk Inventor Nastran and SCIA Engineer.
Installation and service
Scope of work:
We provide complete assembly of new cranes, crane tracks, steel structures and special handling equipment. Our work begins with technical preparation and on-site surveying and ends with the handover of the equipment to full operation, including load testing and necessary documentation.
For crane tracks, we carry out complete assembly of beams and rails - including levelling, anchoring, installation of safety systems against falling from height and load testing. Rectification of rails, replacement of clamps, adjustment of base plates and geodetic survey with protocol can also be part of the delivery.
Service
We follow up existing cranes and lifting equipment with regular and one-off servicing. We supply spare parts, repair of mechanical and electrical parts, revisions and adjustments of the control according to the current requirements of the operation.
Our service offer includes repairs and modifications of crane tracks - from condition analysis to replacement of damaged beams and rails to strengthening or modification of supporting structures, repairs of anchorages, leveling of track unevenness and underflooring with high-strength grouting. The aim is to increase safety, extend service life and keep crane downtime to a minimum.
We pay special attention to the hanging and gripping devices. We carry out overhauls and refurbishments of coil clamps, clamp and casting traverses, C-hooks, grabs, crane and slewing pulleys, electromagnets and other equipment - from diagnostics and NDT inspections through replacement of worn parts to new surface finishes and load tests including protocols.
Construction and design services
Every project starts with an understanding of the technology and operating conditions. We determine the type of loads, frequency of handling, working environment, required service life and method of operation. Based on these inputs, we design the concept of the crane, grippers, steel structures or special manipulators to safely meet the required parameters in the long term.
Our services include technical and technological projects, detailed projects and studies of possible solutions. We can compare different concepts in terms of operation, maintenance requirements and future technology development. The customer thus receives not only drawings, but above all a well thought-out solution with clear justification.
Design of new and unconventional solutions:
We often encounter situations where a standard crane or conventional gripper is not enough. In such cases, we design special equipment - for example, for handling atypical loads, working in extreme conditions or automated operation.
We rely on our own design group, experience from previous implementations and cooperation with specialist departments. We look for solutions that are technically feasible, safe, sustainable in terms of service and at the same time respect the economic possibilities of the project. We take non-traditional assignments as an engineering challenge, not as a complication.
Studies, expertise and consultations:
In addition to complete projects, we also prepare feasibility studies, alternative solution assessments and expert opinions on partial technical problems.
Our services also include consulting activities - from a one-off consultation on a specific project to long-term technical support. The aim is to ensure that the customer always has a comprehensible basis for their decisions based on calculations and practical experience.
Security and special systems
Our supplies include various safety features that we design according to the specific operation and type of handling. These include in particular:
Anti-collision systems for cranes on the same runway, to prevent cats or bridges from colliding with each other and to allow safe simultaneous operation of equipment.
Overload and weighing systems, ensuring load monitoring and timely disconnection of the stroke when the set limit is exceeded. They also allow more precise control of the loads being handled.
Systems to ensure simultaneous movement of the left and right sides of the crane, to help prevent bridge crossing, uneven loading of the structure and subsequent failures.
An important group are emergency braking systems for lifting, used mainly on foundries and other cranes with a high risk of damage. HBS special emergency disc brakes are designed as a separate brake system, working as a safety feature of the lifting unit. By monitoring the condition of the cable drum and other elements, they assess the occurrence of a dangerous situation and, if necessary, automatically brake the movement, even in the event of a power failure or loss of pressure in the hydraulics.
Monitoring, traffic monitoring and evacuation elements
In addition to providing immediate security, we also focus on long-term monitoring of the operation of mechanisms. Systems for monitoring the running time and behaviour of machinery, load movement and correct gripping enable better maintenance planning, early detection of abnormal phenomena and reduced risk of accidents.
Special systems and automation
In addition to standard security features, we have long been involved in special control and automation systems. These include:
Fully automated cranes and lifting equipment, where work cycles are controlled automatically according to technological requirements.
Synchronisation of the movements of two cranes on one track or multiple cranes on multiple tracks, including the coordination of lifts when handling long or extremely heavy loads.
Development of new solutions in the field of load handling, responding to specific customer situations - from special modes of movement to continuity with technological lines.
Integration into new and existing facilities
We integrate safety and special systems both in newly delivered cranes and as retrofitting on existing equipment.

Electrical installations and electrical renovations
The electrical equipment of cranes and handling devices has a fundamental impact on their safety, reliability, and operational efficiency. We provide design, modifications, and complete refurbishment of electrical installations for overhead, gantry, and special cranes, including material handling equipment in demanding industrial operations. For every project, we base our work on the current technical condition of the equipment, operational requirements, and applicable technical standards.
The reconstruction of electrical installations often follows the modernisation of the mechanical parts of a crane or the need to increase the safety and reliability of older equipment. Within these projects, we replace obsolete or worn-out components, modify control cabinets, cable routes, and adapt crane control to current technical standards. The scope of implementation also includes the inspection and modification of power supply systems, protective elements, and safety circuits.
Implementation procedure:
Every project begins with a technical assessment of the existing electrical installation. Based on this, we prepare a proposal for modifications or a complete refurbishment, taking into account:
Type and age of the device
Method of operation and work cycles
Operator safety and protection requirements
Integration options with existing technology
Following approval of the solution, we ensure the manufacture or modification of control cabinets, the installation of new components, the fitting of cable routes and the subsequent commissioning of the equipment, including functional tests.
Benefits of upgrading electrical installations:
Modernisation of electrical equipment brings a number of practical advantages for operation:
higher operational reliability of equipment
Increased security when handling loads
simpler diagnostics and maintenance
Device adjustment current technical and safety requirements
option integration of modern control systems
Thanks to a properly designed electrical installation, a crane or handling equipment can operate more reliably, with lower maintenance requirements and with a higher level of safety for both the operator and the surrounding technology.
