Harnessing the power of forced liquids was a discovery of a Greek inventor and mathematician who lived before the first century B.C. Hydraulics, a Greek word, reflects the origins of the science that makes boom cranes capable of lifting a great weight. DEL Hydraulics has a 70-year history as a leader in truck equipment manufacturing using scientific principles to develop cranes and a range of related products.
DEL Maxilift Telescopic Mono Stiff Boom Cranes
A reputation for sturdiness, reliability and ease of handling recommends the Maxilift line of truck-mounted telescopic cranes. With capabilities that range from lifting 7,400 – 35,400 pounds and a reach of up to 22 feet, Maxilift cranes feature technological superiority and simplicity in a compact machine. Their weight to maximum load capacity provides efficiency on job sites, and a remote control system helps ensure convenience and safety.
Maxilift cranes comply with the guidelines of the German Industrial Standard (DIN), an internationally accepted formula that manufacturers use to predict the structural life of working equipment. The duty cycle and the load determine the working life of hydraulic cranes, and owners of Maxilift cranes can expect to receive 15 years of productive work. The attention to detail in the finishing process produces a surface that protects it against corrosion.
Ideal for mounting on light vehicles, the Maxilift line features a variety of versions that can meet any demand. The smallest model, the ML 110 – 11.1 offers a standard outreach from 9’2” to 12’3” and 330° slewing with a worm screw. The ML 150 – 1.5 has a standard outreach from 9’10” to 13’2” and a 330° slewing rotation with worm screw. Outreach increases incrementally through the series that includes the ML 510 that offers a standard outreach from 11’11” to 22’4” and 330° ball bearing slewing rotation.
A feature that makes a Maxilift crane a preferred choice on construction sites is the ease of installation at any point on a truck to avoid loss of payload space. The loading movements are fluid, gradual and accurate while requiring little effort from an operator. Each crane model offers a range of technologically sound safety systems.
DEL Cobra Telescopic Service Cranes
The boom system in the Cobra series of truck-mounted telescopic cranes consists of a single piece of renowned high-tensile Swedish steel that uses a single robot-created weld bead. With a capacity for lifting weights of up to 67,000-foot pounds and the ability to reach up to nearly 28 feet, the Cobra crane has superior structural integrity. The familiar hexagonal shape provides exceptional strength in the boom. Even though the Cobra’s dead weight is lower than competitors’ models, it offers an excellent crane weight to maximum load capacity ratio.
Radio remote or cable controls enhance the operation of the technologically advanced crane that features trouble free performance. Programmable overload protection with a transducer ensures load limiting, and a large LED display informs the operator of diagnostics and safety checks. The intelligent design of the Cobra features DC electric winches or planetary hydraulic winches to ensure high levels of efficiency on the job. Models 5500 through 12000 have unlimited continuous slewing that prevents wasting time on positioning and increases efficiency.
In production since 1996, Cobra cranes have a proven record of performance in extreme weather conditions. Extension cylinders within the boom system provide protection from the elements, enhancing reliable performance. The Cobra line’s safety features include winch wire ropes that do not twist. As an enhancement to durability, the polymeric wire rope sheaves do not rust.
DEL Maxistab Hydraulic Stabilizers
Supplementary outriggers can help stabilize a pickup, truck, or service vehicle when the weight of the crane and its load creates a need for equalizing. The engineering design achieves the best weight to performance ratio. Structural components of high tensile steel ensure superior performance to stabilize vehicles. DEL’s patented “K” fixing system provides maximum versatility for the adjustment of cylinders without requiring welding, and variable length cylinders offer choices for specific uses.
Side rods extend manually on small wheels that have a double safety locking system. Hydraulic side rods slide on runners that include inner cylinders and an automatic locking system. Stabilizer legs have high margins of safety and can meet radial and axial stresses.
An improvement to the manufacturing process includes sandblasting of the Maxistab’s structural parts before application of a primer coat and a final coat. Each assembled stabilizer receives a coat of bi-component polyacrylic paint in a black, half-color luster. The technologically superior coating provides a long-lasting finish that guards against chemical and environmental effects in addition to UV rays and corrosion.
