Mechanical construction TZ Lift Trolleys
Mechanical construction
EdmoLift TZ Lifting Trolleys comprise a single scissor mechanism, with a vertical double scissor mechanism for TZD.
The lifting force is achieved from a single acting cylinder, connected between the chassis and the centre crossbeam in
the scissor mechanism.
The scissor mechanism is located in a chassis with two fixed and two swivelling wheels. The swivelling wheels have a
parking brake and a rotation-locking device. Ensure the parking brakes on the rear wheels are applied when the Lifting
Trolley is left unattended on sloping ground, and when loading or unloading, to avoid unintentional movement. The
push handle is used to manoeuvre the Trolley.
The hydraulic system is powered by a foot-operated pump or by a battery powered hydraulic power unit, located at the
handle end.

Foot pump
Raising is by means of pumping with the foot pedal. A relief valve, set on delivery, limits the lifting force. This valve
must not be adjusted without EdmoLift's agreement. Lowering is by means of pressing the lowering handle, of hold-to-
run type, whereby a wire or a rod will open the lowering valve. A flow control valve limits the lowering speed to approx.
100 mm/s at full load.
Battery operation
Raising is controlled by means of a push button, which operates the electric motor. The lifting motion will continue as
long as the button is pressed, or until the top position has been reached.
Lowering is achieved by pressing the lowering handle, of hold-to-run type, whereby a wire or a rod will open the
lowering valve. A flow control valve limits the lowering speed to approx. 100 mm/s at full load. Maintenance-free
batteries, 12 V DC, 28 Ah, and an on board battery charger 4 A, for connection to 1-phase, 220 - 240 V, 50 Hz mains
outlet, is included.
