1. Product Overview
Congratulations on your purchase of a Simpro Dumpmaster bin-tipping machine.
Dumpmaster is probably the safest and most reliable bin tipper on the market, having been
in continuous production for more than thirty years.
Dumpmaster is very versatile and can be used in numerous applications, ranging from
emptying rubbish bins into skips to pouring food ingredients into mixers. Regardless of the
application, Dumpmaster has proven to be safe, reliable, and
economical to operate, year after year.
1.1 Key features
Key features of the Dumpmaster include:
1. A unique tipping action
whereby bins are lifted
straight up, and then gently
rolled forward around the lip
of the skip or hopper being
emptied into. Benefits of this
design include a small
‘footprint’, and a wide range
of tipping heights available, from
700mm to more than six metres.
2. A standard weight capacity of 250kg.
3. A very reliable, maintenance-free design.
4. A fully hot-dip galvanised frame and cradle
as standard (with options for full or partial
stainless steel for hygiene-critical areas).
5. A standard cradle which lifts almost all
EN840 wheelie bins without clamping or
retaining.
6. A modular design which can be easily modified to suit a wide range of non-standard
bin sizes, shapes, and weights.
1.2 Construction
The Dumpmaster consists of a steel frame with vertical masts and stabilizing legs, bin cradle,
hydraulic ram, hydraulic powerpack, powerpack cover, control panel, electronic control
systems, guarding, castor wheels, and power lead or charging cable.

User Manual // Simpro Dumpmaster®
Original Instructions // English // v119.0 // October 2022 // Page 6
1.3 Mechanism
When the RAISE button is pressed, a hydraulic ram is extended, which pulls on an
arrangement of chains, causing the bin cradle to travel vertically in the masts. The cradle is
inverted at the appropriate height by an arrangement of arms, rollers, and a curved track.
The ram is supplied by a hydraulic power pack, which may have a 3-phase, 1-phase, battery,
or compressed-air motor. Electrical, hydraulic, and / or mechanical control mechanisms
allow the operator to raise or lower the bin in a controlled manner.
1.4 Safe Working Load
The Safe Lifting Capacity of the standard Dumpmaster is 250kg (550lb).
Safe Working Load (SWL) is a gross figure, referring to the weight of the bin, its contents,
and any other objects placed on the cradle.
Custom machines may be specified with different Safe Working Loads. The rating plate
should be the first point of reference to determine SWL on any given machine.
Never attempt to lift bins that are heavier than the factory-specified Safe Working Load.
1.5 Duty cycle
The duty cycle of the Dumpmaster depends on the type of power supply and powerpack
that is fitted to the machine, as well as various environmental factors and the manner in
which the machine is used. The figures given below are estimates only.

1.7 Noise emissions
The noise emissions of the Dumpmaster do not typically exceed ~60 dB(A) at the operator’s
ear. Hearing protection is recommended if operating the machine for extended periods.
ISO standards for machinery safety specify that noise emissions are to be measured in A-
weighted decibels (dB(A)), a unit of volume which is adjusted to reflect the sensitivity of
human hearing. The measurements are taken at a point 1.6 metres above the ground at
the operator’s working position.
1.8 Environmental restrictions
The Dumpmaster may be used indoors or outdoors. However, the following restrictions apply:
1. Minimum floor area 2 square metres, with a clear passage to exits;
2. Height above sea level not more than 1000m;
3. Ambient temperature not higher than +40℃and not lower than -10℃;
4. At ambient temperatures above 35℃, the relative humidity should not exceed 50%; at
lower temperatures, higher relative humidity is permitted;
Never operate the Dumpmaster in explosive, corrosive, acidic or alkaline environments.

2.2.2 Type-E Cradle
2.2.2.1 Emplacing bins
Open the door and place the wheelie bin onto the cradle. For
full-size 240L bins, both wheels should be positioned into a catch
(on either side of the cradle). For smaller bins such as 60L, 80L,
120L and 140L, only the left-hand wheel needs be positioned into
a catch. Once the bin is correctly emplaced, close the door.
The wheel catches are designed to work with standard EN840
wheelie bins from leading brands such as Europlast, Sulo, ESE,
Weber, Craemer, OnePlastics and Trident.
Some smaller bin manufacturers use axles of different lengths. If the distance between
the wheels is slightly too large or small, the wheels may jam against the catches,
preventing a secure emplacement. Should this occur, simply unbolt and remove the
right-hand wheel catch. All bins can be securely retained using the left-hand catch only.
Some smaller bin manufacturers use tyres which are too wide to fit inside the wheel
catches. Should this issue occur, simply insert additional packers (flat washers) onto the
wheel catch mounting bolts, to increase the spacing as needed.
2.2.2.2 Removing bins
Open the door and, using the grab-handle provided, remove the
wheelie bin from the cradle.
2.2.3 Type-C Cradle
2.2.3.1 Emplacing bins
Open the door and place the wheelie bin into the machine, positioned
centrally against the cradle backplate. Take care that the lifting teeth
are properly hooked into the bin combing; smaller bins such as 60L
and 80L may need to be tilted or lifted slightly to ensure a proper
‘catch’. Once the bin is correctly emplaced, close the door.
2.2.3.2 Removing bins
Open the door and, using the grab-handle provided, remove the wheelie bin from the
cradle. The bin may need to be tilted slightly to disengage the comb from the cradle ‘teeth’.
2.2.4 Type-A Cradle
2.2.4.1 Emplacing bins
Open the door and place the trash cart into the machine, positioned
centrally against the cradle backplate. Take care that the lifting
catches are properly hooked into the front of the cart; some carts may
need to be tilted or shaken slightly to ensure a proper ‘catch’. Once
the cart is correctly emplaced, close the door.
2.2.4.2 Removing bins
Open the door and, using the grab-handles provided, remove the
trash cart from the cradle. Some carts may need to be tilted or shaken
slightly to detach them from the lifting catches.
