Intelligent conversion solutions for construction and utility vehicles

Due to ever higher quality and efficiency standards, requirements for construction machinery nowadays often exceed the standard equipment. As a specialist for the optimization of construction machinery, DMS develops complete conversion kits that will provide machines with additional functions. Our conversions are field-tested and used throughout Europe. They are also installed into some manufacturers’ standard models on the market.

Auxiliary control circuits and
hydraulic functionality extension

With ready-to-install hydraulic conversion kits from DMS, machines can be adapted to meet individual requirements. By using existing components or installing additional components, the operation of Powertilts, hydraulic quick couplers or complex hydraulic attachments such as grabs is made possible.

Auxiliary Hydraulic Circuits

Creation of additional hydraulic circuits by switching existing functions or installing independent circuits with the help of a secondary control valve


Hydraulic circuit with couplers installed on the arm


Hydraulic circuit for coupling systems, single-acting [e.g. Lehnhoff] or double-acting [e.g. Martin]


Hydraulic circuit for Powertilt

Intuitive control

The operation of a swinging mount grab (open/close shells) via joystick function 'open/close bucket cylinder'

Two-way control

Mechanical control (pedal) or electrical control (joystick)

Hybrid Conversion Kit for
compact and mini diggers

Certain environments require emission-free action. For this purpose, DMS, in cooperation with the manufacturer Takeuchi, has developed a hybrid excavator conversion kit. The conversion consists of an electric motor installed on the excavator in addition to the existing diesel engine. The electric operation via power cable does not restrict the range of functions or performance.
