20 ton workshop rail mounted semi gantry crane Electric hoist semi
20 ton workshop rail mounted semi gantry crane is a kind of light
type crane, commonly used in modern production. In workshops where
part utilization of shop bay is required (as in a tool room
attached to a press shop), a Semi-Goliath/Gantry Crane is used. In
such a configuration, one end-carriage of the crane will travel on
the regular gantry rail while the opposite end-carriage will travel
on a rail mounted typically on the ground or at a lower elevation.
This crane is a general purpose light crane used in workshop or
outdoors. The leg height of semi-gantry crane can be different
according to the engineering needs on the construction field.

Notes:The foregoing attached table shall only be used for reference. The
actual application shall be appropriately modified according to
1. It could be used in outdoor or indoor warehouse for loading and
unloading. Water-proof cloth is needed in out door operation.
2. Saving the investment and space, with reasonable structure,
favorable performance, easy installation, reliable traveling,and
convenient maintenance, strong ability of lateral load proof, etc.
3. It is usually used in machine shop to carry materials. The crane
has two operation modes including control on ground and remote
4. Variable speed through VVF Drive
5. Wireless Radio Remote control
Safety Protection of 20 ton Semi Gantry Crane:
1. Overload limiter;
2. Polyurethane buffer, long service life and impact resistance;
3. Crane travelling limit switch;
4. Loss pressure protection, fault phase protection;
5. Emergency stop system;
6. Lifting height limiter;
Motors: The motors are used special crane duty suitable for
frequent starting , reversing & braking in accordance with ISO
9001:2000 ISO 14001:2004. Motors are totally enclosed in dust proof
construction foot / flange mounted TESC / TEFC, Sq. cage motors
with integrated safety brakes, insulation class F, IP54 protection
for hoisting, CT & LT motions.
Electrical Panel: Modular design, ease to install and maintain,
reliable operation, fuses less circuitry, ducted wiring and compact
terminals. Motor overload protection to prevent overloading.
Brakes: Independent Hydraulic Brake makes the crane safer and
easier to control
