All DH Series dock levelers incorporate the use of
hydraulics to raise and lower both the platform and
lip. A single push button activates a hydraulic pump
for operating both lip and hoist cylinders. Unit con-
forms to OSHA, U.S. Department of Commerce
Standard CS-202-56 and is manufactured in com-
pliance with the American National Standard of

Devices (ANSI) MH 30.1.
The DH Series Leveler is controlled remotely from
wall mounted control panel. An array of optional

is from 12" above to 12" below dock level. Lip
keepers welded to frame members provide night-
time security and cross-traffic support. Full operating
range toe guards are provided as standard. Mainte-
nance prop with ‘Lock-out Tag-out’ capability is
provided as standard. Factory finish includes rust
inhibitive prime coat industrial grade finish. Each

The platform is constructed of ¼” thick 4-way high
tensile 50,000 minimum yield A572 steel safety tread-
plate (3/16” for 20,000 Comparative Industry Rating
(CIR)). Platform is reinforced and supported by full-
length roll formed “C” channels (20,000, 25,000 and
30,000 lb CIR), structural “C” channels (35,000 &
40,000 lb CIR), and a combination of structural “C”
channels and “I” beams (45,000, 50,000 and 60,000 lb
CIR). Front and rear header plate is of either ½” x 7”
or ½” x 8” hot rolled steel. DH Series lips are made
of 4-way safety treadplate, the 20,000 and 25,000 lb
CIR are 1/2” thick, the 30,000, 35,000 and 40,000 lb
CIR are 5/8” thick, and the 45,000 50,000 and 60,000 lb
CIR are 3/4” thick. The standard lip length is 16” on all
capacities except the 60,000 CIR which is 18”. Hinge
tubes are 1 3/4” OD x 5/16” wall, 1 7/8” x 3/8” wall,
2 1/8” x ½” wall, or 2 5/8” x 3/4” wall depending upon
CIR. All lip hinge pins are 1” M1044 steel. Steel lip
gusset are standard on 50,000 and 60,000 lb CIR
models. Steel header gussets are standard on all models
35,000 lb CIR and above. All platforms are designed
